Undead Unluck

Undead Unluck follows Fuuko Izumo, a girl whose touch brings lethal bad luck, and Andy, an immortal man who desperately wants to die.

Together they get dragged into a secret global organization of superpowered “negators” who fight monstrous beings called UMA and the gods who toy with humanity.

The manga ran in Weekly Shonen Jump from issue 8, 2020 to issue 9, 2025 and totals 27 volumes / 239 chapters.

It won the 2020 “Next Manga Award” (Comics category) and reached over 1.8 million copies in circulation by 2022.

The TV anime aired from October 2023 to March 2024 in a 24‑episode, two‑cour run produced by david production.

A 1‑hour special, Undead Unluck: Winter Arc, produced by E&H production, is scheduled to air on nationwide TBS network affiliates in late 2025.

The series is often nicknamed “Undead Unluck” or by its Japanese fandom abbreviation “UndeRa.”

It is known for tight plotting, an evolving power system around “negating” rules, and a surprisingly emotional time‑loop meta‑story.

Fuuko Izumo has spent ten years shut in after her “Unluck” ability caused a plane crash that killed over 200 people, including her parents.

Her power makes anyone who touches her skin suffer random disasters whose severity scales with intimacy and time of contact.

After finishing her favorite long‑running romance manga, Fuuko decides to commit suicide.

Before she can, she is interrupted by Andy, a scarred, muscular man who instantly regenerates from any injury and proudly calls himself “Undead.”

Andy cannot die no matter what he does, and he is sick of his endless life.

He decides Fuuko’s Unluck is the ultimate weapon to finally give him a “best death,” so he latches onto her—literally and figuratively.

Their chaos draws the attention of Union, a secret organization of negators who manage UMA and other negators for the sake of ordinary people.

Union hunts them at first, but after a series of clashes they offer Andy and Fuuko a place on their elite team if they help clear deadly “quests.”

The quests are dictated by Apocalypse, a sentient stone book that relays challenges and penalties from the sun‑god Sun.

Failing quests adds new “rules” to the world as powerful UMA, and if too many rules accumulate, the world faces a terminal event called Ragnarok.

Fuuko and Andy join Union’s round‑table team, confront rival negator group Under, uncover the truth about time‑loops, and work toward killing Sun itself.

Along the way they relive tragedies, rewrite fates in a new loop, and gradually turn Fuuko’s cursed Unluck into a hope for everyone’s happy ending.

Negators and “Un‑” Abilities

Negators are people whose very existence denies a specific “rule” of the world.

Each power is named Un‑Something (for example Unluck, Undead, Untruth).

Negator abilities fall roughly into two categories:

Self‑targeting (the user negates a rule as it applies to themselves, like Undead or Unstoppable).

Other‑targeting (the user negates something in others or the environment, like Untruth or Unchange).

Some powers activate automatically whenever conditions are met, while others are volitional but have strict trigger rules.

Crucially, those rules can evolve as the user’s understanding or emotional state changes, allowing abilities to “grow.”

When a negator dies, their “Un‑” concept transfers to a new host somewhere in the world.

Tragedy at the moment of awakening is common—many characters’ origin stories center on accidental mass casualties or loss.

UMA (Unidentified Mysterious Animals)

UMA are monstrous beings representing added “rules” or concepts in the world, such as Fire, Galaxy, Seasons, or Disease.

When a core UMA dies, its concept is erased or drastically altered worldwide, causing radical changes in reality.

Some UMA are concept‑type, controlling big abstract rules like seasons or language.

Others are phenomenon‑type, embodying more tangible forces like rust, gravity, insects, or magma.

Each major UMA contains a core that must be destroyed or captured to resolve the threat.

Defeating or capturing them often triggers quest rewards or penalties, including new rules, artifacts, or information.

UMA can also produce Junior offshoots, smaller creatures or transformed humans that carry derivative rules.

Once a human has become a Junior, there is currently no way to return them to normal.

Gods, Rules, and Loops

The universe is run by two deities: Sun and Luna.

Sun created UMA and most of the added rules, treating the world as a board game between UMA and humanity.

Luna, manifesting as the Moon, created artifacts and occasionally supports humanity, but mostly as an amused spectator.

Only when pushed—usually by Union’s leader—does Luna take active steps, like enabling time‑loops.

The world began without many familiar rules: no disease, no races, no language diversity, no galaxy.

Over countless cycles, Sun adds rules through UMA as punishments or “game mechanics”; some become Master Rules that never disappear between loops.

When too many rules (up to the 100th) pile up, Ragnarok begins.

Sun descends, smashes the planet, and everything ends—unless certain conditions allow a Loop, sending selected beings into the next world.

Union

Union, formally the “Unidentified Phenomenon Control Organization,” is a secret global group.

Its mission is to safeguard ordinary people by controlling or eliminating UMA and handling negator incidents.

Union is structured around a Round Table of up to eleven negators, each assigned a numbered seat.

Only seated members can join Apocalypse quests and earn points, which are required to qualify for time‑loop travel.

Round Table members receive matching suits, translation‑tie devices that bypass language barriers, and badges needed to enter quests.

Seat numbers reflect accumulated achievements; seats shift when people die or out‑perform each other.

Union’s methods can be ruthless toward negators and UMA, but the principle is always “protect innocent lives first.”

Behind the scenes, their true long‑term goal—led by Juiz d’Arc—is to build enough power to kill the god Sun and end the loops.

Under

Under is a negator organization that opposes Union.

Its members share a common theme: they have been broken by the world’s rules and see destruction or god‑killing as their only path.

Outwardly, Under seeks global conquest and is willing to sacrifice civilians freely.

In reality, its leader Billy Alfred prioritizes killing Sun, even if that means using and betraying everyone, himself included.

Many Under members formerly belonged to Union or were targeted by Union quests.

Under’s insignia is an inverted “Un” mark, mirroring Union’s.

Apocalypse and Quests

Apocalypse is a sentient stone book and one of the oldest artifacts.

When all Round Table seats are filled, it awakens and presents a list of quests with deadlines.

Quests typically involve:

Capturing or killing specific UMA.

Capturing or killing specific negators.

Reaching designated locations or conditions.

Completing a quest grants rewards like:

Locations of UMA, negators, or artifacts.

Rule alterations (for example, unifying world languages).

Added information about gods, loops, or artifacts.

Failure triggers penalties, usually the addition of dangerous UMA or new global rules that make survival harder.

Quests can be skipped, but time jumps a full year in the outside world, costing preparation time.

Fuuko Izumo (Unluck)

Fuuko Izumo is one of the two main protagonists and the emotional core of the series.

She is an 18‑year‑old girl in a knit cap who once lived as a shut‑in after her touch killed over 200 people in a plane crash.

Her ability Unluck (Unluck) denies “good fortune” for anything she touches directly with bare skin.

Mishaps can range from small “something falls on your head” accidents to massive disasters like car pileups, building collapses, and even meteor strikes.

The longer and more intimate the physical contact, and the stronger Fuuko’s feelings for the target, the worse the resulting bad luck.

Because of this, she wears gloves and covers up as much as possible, tortured by the idea she can never hug anyone safely.

Meeting Andy drags her back into the world.

He convinces her to weaponize Unluck, not just to kill him, but to save others and win the impossible battles ahead.

Over time Fuuko’s control and interpretation of Unluck evolve.

She learns to tailor bad luck to an enemy’s nature, harm UMA directly, and even embed Unluck into beloved objects as weapons.

After a vast chain of events and betrayals, Fuuko eventually assumes Seat 1 at the Round Table.

She becomes the “boss” of Union and the one who triggers the 101st loop, carrying everyone’s hopes into a radically prepared new world.

In the new loop, Fuuko spends over 170 years quietly preparing and intervening earlier in potential tragedies.

She becomes more proactive, sharper in combat, and much more confident, but remains deeply kind and emotionally vulnerable.

Andy (Undead)

Andy is the other main protagonist, a rough‑edged immortal with a surprisingly straightforward heart.

He has wild hair, a massive frame, and a strange card‑like artifact stabbed into his forehead that seals away another persona.

His ability Undead (Undead) is a self‑targeting denial of death.

Any lethal injury triggers explosive regeneration; he can re‑grow lost limbs, reassemble from chunks, and remain conscious through dismemberment.

Because his body will always push away death, non‑fatal injuries like bruises and dislocations may linger unless healed normally.

If his head is sealed in a container that prevents the body from “reaching” it, regeneration is temporarily halted.

Andy has lived at least 200 years and has experienced many professions: soldier, mercenary, swordsman, even hairdresser.

He is foul‑mouthed, impulsive, and often shamelessly naked (because his clothes do not regenerate), yet he is honest, loyal, and quick to apologize when wrong.

In combat he weaponizes his regeneration in flashy ways:

He ejects limbs as flesh bullets, uses explosive regrowth for propulsion, and wields an unbreakable katana called Kurikara, forged by the negator Unbreakable.

The card in his head is the artifact Remember, which can either carry memories across loops or erase them.

Removing it lets the original persona Victor surface, dramatically boosting combat prowess but altering his personality.

In the new loop Andy operates separately from Fuuko for a time.

He travels the world building power to kill Sun, while Fuuko quietly arranges people’s fates from the shadows.

Victor (Undead – Original Persona)

Victor is the original owner of the Undead ability who surfaces when Remember is removed.

He is colder, more ruthless, and anciently battle‑hardened, with a deep bond and complicated romantic tension with Juiz d’Arc.

Victor has fought through many previous loops and is infamous as the “God of Victory” in many battlefields.

Rather than just regenerate, he uses his blood and body in sophisticated, weapon‑like ways, far surpassing Andy’s early control.

Despite his harsh demeanor, Victor cares deeply about humanity and especially about Juiz.

He is willing to sacrifice his own happiness to give others a chance at breaking the loop.

Juiz d’Arc (Unjustice)

Juiz d’Arc is Union’s founder and long‑time boss, usually holding Seat 1 until Fuuko takes over.

She wears military‑style clothing and a mask that covers the top half of her face, hiding a long history of battle and sorrow.

Her ability Unjustice (Unjustice) denies an opponent’s sense of justice and flips their intended goal to its opposite.

By exposing her face and invoking the power, she can force enemies to act contrary to what they see as “right.”

Unjustice targets purpose, whereas Untruth (Untruth) targets method.

This makes her one of the few negators capable of tangling seriously with the strongest UMA.

Juiz has looped countless times using Ark, carrying forward memory and strategy while gathering negators in each world.

To her, protecting Earth and its innocent people is the only justice worth pursuing, even if it means endless suffering.

Shen Xiang (Untruth)

Shen Xiang is a muscular, cheerful Chinese martial artist and Round Table Seat 2.

He fights using “True Bajiquan,” a high‑impact style, and wields the artifact Ruyi Jingu Bang, a staff that can extend to absurd lengths, plus the flying cloud Kinto‑un.

His ability Untruth (Untruth) denies the truth of an action.

By sincerely “liking” someone and keeping them in his line of sight, he can force them to do the opposite of what they intend (attack becomes defend, flee becomes charge, etc.).

Shen is a thrill‑seeking battle maniac, but he carries deep trauma over his younger sister Mei.

An earlier tragedy orchestrated by his master Feng Kowloon drove his hunger for strength and revenge.

Because Untruth requires genuine affection to target someone, Shen constantly manages his feelings and line of sight to prevent accidental triggers.

In everyday life he even averts his gaze from people he cares about, like Fuuko, Andy, and Mui.

Later, Shen dies protecting Mui and is resurrected as a jiangshi (a hopping corpse) through an artifact.

His negator power transfers to Mui at that point.

In the new loop, because the original tragic trigger is averted, Mei survives and Shen’s relationships are healthier.

He eventually awakens as a negator again and joins Union under very different emotional circumstances.

Billy Alfred (Unfair / “Fake” Unbelievable)

Billy Alfred is initially introduced as Union’s Seat 3, a relaxed ex‑mercenary with a gentle smile and dark glasses.

He takes care of Tatiana and claims his power is Unbelievable—a gun‑based “impossible shot” ability.

In truth, Billy is the secret leader of Under.

His real negator ability is Unfair (Unfair), which denies the “fairness” that each negator only has one ability.

Unfair lets him copy other negators’ powers, as long as they see him as an enemy.

He can store multiple abilities and even combine them (for example, using Undead to heal the damage from Unstoppable).

After years of pretending to be Union’s ally, Billy betrays the Round Table during a critical quest and steals the table and Apocalypse.

He does it not for personal gain but to grab every advantage possible in killing Sun, even if everyone despises him.

Once he genuinely stops seeing Fuuko as an enemy and shifts his view of Juiz, he loses access to Unluck and Unjustice.

In the new loop, the conditions of his copying power rewrite themselves based on his self‑image: it now keys off admiration of strength instead of hostility.

Tatiana (Untouchable)

Tatiana is a Russian child negator and Round Table Seat 5.

She lives permanently inside a large spherical mech suit called the “Sphere,” both as armor and life support.

Her ability Untouchable (Untouchable) is a self‑targeting field that annihilates anything that comes into contact with her body.

Normally this field extends only a few meters, but emotional spikes can expand it enough to obliterate buildings or even cities.

Because the field sits directly on her skin and hair, she cannot wear clothes or be physically touched.

She eats through an opening that temporarily suspends the field around her mouth, and the Sphere works by tightly controlling the field’s boundary.

Tatiana accidentally killed her family and neighbors when her power manifested on her fifth birthday.

Rescued and mentored by Billy and inspired by Gina Chamber, she clings to Union as her found family.

Fuuko becomes her first female friend, challenging Tatiana’s self‑image as a living weapon.

Tatiana’s battles are some of the series’ most visually spectacular, combining Untouchable shockwaves with the Sphere’s mech arms and beam cannons.

Nico Vorgeil (Unforgettable)

Nico Vorgeil is Union’s mad‑scientist genius and Round Table Seat 8.

He runs the Union lab, designing weapons, support gear, and outrageous gadgets for negators.

His power Unforgettable (Unforgettable) denies forgetting.

From the moment it awakened, Nico has been unable to erase any new experiences from his memory.

This is a curse as much as a gift.

He remembers his wife Ichiko’s painful death during childbirth with perfect clarity, while earlier happy memories with her fade naturally.

Unforgettable makes him uniquely suited to interface with dangerous artifacts that bombard users with ancient loop memories.

He also uses remote‑controlled black spheres called Psycho Pod Berries for ranged attacks and mobility.

In the pre‑Fuuko loop, Nico is driven to betrayal and death through a tragic deal with the UMA Ghost, then redeems himself in a final act.

In the new loop, he has not yet awakened his power and instead supports the team with pure science, showing how capable he is even without being a negator.

Top Bull Sparx (Unstoppable)

Top Bull Sparx is a hot‑headed, dark‑skinned teen sprinter from Brazilian favelas and Round Table Seat 7.

He is brash, impatient, and determined to literally kick the face of God.

His ability Unstoppable (Unstoppable) denies stopping once he exceeds a certain speed and attempts to slow down.

Instead, a huge external force kicks in and accelerates him further, turning him into a human projectile.

To stop, Top must break his own bones or otherwise radically disrupt his physical state to “reset” the speed condition.

To maximize this, he wears a powered suit called Un‑ST Tachyorizer, which channels and stabilizes his insane momentum.

Top’s power first manifested during an athletics trial, leading to the death of a friend he tried to let win.

Crushed by guilt, he was recruited by Juiz and has since resolved to use Unstoppable only to protect others and fight Sun.

Chikara Shigeno (Unmove)

Chikara Shigeno is a timid Japanese high schooler who becomes Round Table Seat 11.

He feels intense guilt over his parents’ deaths, which were caused indirectly by his power awakening.

His ability Unmove (Unmove) denies motion within his field of view while his own limbs remain motionless.

When active, anything he sees—bullets, falling debris, enemies—freezes in place until he moves his arms or legs.

At first, Chikara triggers Unmove accidentally through fear and trembling, making it unreliable.

Nico later equips him with special goggles that let him select targets and floating pods so he can move using mental commands while keeping his limbs still.

Chikara’s growth arc revolves around learning to act despite fear, turning panic paralysis into a conscious tactical choice.

He provides critical battlefield control in many later missions, freezing threats so others can strike safely.

Void Volks (Unavoidable)

Void Volks is a hulking ex‑heavyweight boxing world champion who once held a Round Table seat before Andy arrived.

He wears a special combat suit and lives with deep regret.

His ability Unavoidable (Unavoidable) denies an opponent’s ability to dodge his attack once he takes a certain stance.

This manifests as a “you cannot avoid this punch” rule in local reality.

During his last title defense match, Unavoidable awoke and killed or maimed his opponent.

Banned from boxing, drowning in guilt and alcohol, he was scouted into Union as a hunter of negators.

Void dies in his fight against Andy and passes his spot to the newcomer.

In the new loop, Fuuko intervenes earlier in his life, triggering his power safely and helping him retire peacefully; he then joins Union as Seat 3 with a brighter personality.

Gina Chamber (Unchange)

Gina Chamber is a Soviet‑born former Round Table member, visually a teen but in reality an elderly woman supported by anti‑aging tech and clever makeup.

She is one of the earliest negators Fuuko and Andy face.

Her ability Unchange (Unchange) denies change in the shape of anything she touches with bare hands or feet.

She can freeze air into invisible barriers or create giant “hands” of hard air for offense or defense.

Decades ago she unconsciously locked the air in a vast region, suffocating 40,000 civilians.

Her guilt drove her into Union’s arms, where she found a twisted kind of purpose.

Gina has loved Andy for over 50 years after meeting him during his imprisonment, clinging to that crush to survive emotionally.

In their duel, Fuuko and Andy manage to outplay Unchange, and Gina dies content, finally released from her self‑imposed stasis.

Fuuko later inherits Gina’s special protective suit.

In the next loop, thanks to Fuuko’s interference, Gina awakens and dies under altered circumstances, and in another branch she even becomes an active ally earlier.

Mui

Mui is Shen Xiang’s loyal subordinate, a serious, capable young woman who wears Chinese‑style clothing.

Her parents were killed by a UMA, and Shen took her in, becoming her savior and martial arts instructor.

Mui is not a negator at first but is extremely skilled in hand‑to‑hand combat and support operations.

She is deeply frustrated by her inability to sit at the Round Table despite her dedication.

During the brutal conflict with Feng Kowloon and the UMA Summer, Mui uses the artifact Death Game to resurrect Shen as a jiangshi.

This costs Shen his negator status and transfers Untruth to Mui herself.

In the new loop, Mui is even more formidable due to extended training, but her emotional dynamic with Shen softens because Mei survives.

She remains one of the most competent non‑Round‑Table allies and later as a negator is downright terrifying in battle.

Nico Lab Team

Nico’s lab is staffed by a small crew of energetic specialists, informally called the Nico Lab Members.

Key faces include Nico’s daughter Miko Vorgeil and technicians named Bow, Zack, Bau, Lang, and Pochcho.

They assist in developing weapons, armor, and various monitoring systems.

When global rules are altered, they use a memory‑sharing device to help Nico and other negators quickly grasp what has changed.

They are not front‑line fighters, but without them Union’s tech and intelligence backbone would crumble.

Their presence also humanizes Nico, showing him as a dad and boss, not just a grim memory hoarder.

Under as an Organization

Under is a loose coalition of negators assembled around Billy Alfred.

Unlike Union’s mission‑driven cohesion, Under is held together by personal motives and mutual benefit.

Several Under members have given up on the idea of “saving the world” and focus instead on the Ark, a time‑travel artifact.

If they cannot fix this loop, they at least want to rewrite the next one for their own lost loved ones.

Under is more combat‑oriented on average than Union.

Its members often wield both lethal negator abilities and numerous artifacts.

Creed Deckard (Undecrease)

Creed Deckard is a towering, scarred soldier with a military demeanor and Under Seat 3.

He mainly uses heavy firearms and later a Gatling gun built into a prosthetic arm.

His power Undecrease (Undecrease) denies the depletion of anything he classifies as a weapon once he has fully expended it.

If he empties a clip or uses the last grenade, that item is restored from nothing, effectively granting infinite ammo.

The catch is that an item must be fully used; if a bomb fails to detonate and is taken away, Undecrease does not activate.

This leads Creed to fight with a deliberate, methodical tempo focused on consuming his entire arsenal in cycles.

In the new loop, his power manifests during a conflict called the Brozha War.

Misunderstood by his superiors, he and his men are abandoned, driving him toward nihilism until Fuuko and company save his unit and redirect his path.

Rip Tristan (Unrepair)

Rip Tristan is a blond surgeon with an eyepatch and Under Seat 4.

He was once a brilliant doctor devoted to saving a single patient: his childhood friend and fiancée, Leila Mirah.

His ability Unrepair (Unrepair) denies healing for any wound he personally inflicts.

Those injuries cannot recover naturally or be treated, and attempts to “heal” them by defeating him are also blocked.

Rip fights with scalpels and kicks powered by the leg‑blade artifact Blade Runner, letting him launch cutting shockwaves and run on air.

He blinded himself in one eye with his own ability as a symbol of his resolve.

In the past, Unrepair awoke in the middle of Leila’s heart surgery, dooming her and crushing Rip and Latla Mirah’s faith.

They turn to Under and the Ark, seeking to resurrect Leila in another world rather than fix this one.

Rip temporarily dies in his clash with Andy and revives as a child via the aging artifact Life Is Strange, later regaining his adult body.

By the end of Ragnarok he loses to Andy over who will use the Ark, entrusting the protection of Latla and Leila’s future to him.

Latla Mirah (Untrust)

Latla Mirah is a poised, beautiful woman and Under Seat 10, Leila Mirah’s elder twin sister and Rip’s childhood friend.

An accomplished fortune‑teller, she once believed completely in her divinations.

Her power Untrust (Untrust) ensures that any prediction she voices will fail, essentially inverting her fortunes.

This lets her paradoxically “predict” the future by stating the opposite of what she wants to happen.

Untrust can also bend the path of attacks she has mentally registered, steering incoming strikes off target.

It makes her an excellent battlefield coordinator and Rip’s tactical anchor.

Latla buries her own romantic feelings for Rip under loyalty to Leila’s memory.

Her arc is about accepting that she deserves her own life as well, not just acting as a supporting character in Rip and Leila’s tragedy.

Feng Kowloon (Unfade)

Feng Kowloon is an ancient Chinese martial arts master and Under Seat 6.

He was once Shen and Mei’s mentor, training them in True Bajiquan.

His ability Unfade (Unfade) denies the progression of aging from the moment it awakened.

Unfortunately for Feng, that moment was when he was already seventy; he remains forever old unless he uses external means to rejuvenate.

He obsesses over strength and despairs that his frail body cannot match his will.

To remedy this, he hoards artifacts, including the rejuvenating Life Is Strange and the counterpart to Ruyi Jingu Bang, Zuixin Tekkan.

In previous loops, Feng orchestrates the lethal confrontation between Shen and Mei to mold a “strongest under heaven” disciple.

He later joins Under on the condition that they help him find youth.

After Life Is Strange de‑ages him to a handsome young form, he becomes even more lethal and flamboyant.

In later arcs, he is captured, and in the new loop he appears younger earlier and clashes repeatedly with Fuuko, ultimately being roped into training Shen properly.

Yusai (Undraw)

Yusai is an older woman swordsman with a regional accent and Under Seat 5.

She once taught Andy swordsmanship and harbored romantic feelings for him.

Her ability Undraw (Undraw) prevents others from drawing whatever she targets—a blade, for instance, cannot be unsheathed.

In major battles she even uses it to keep cherry blossoms from falling, aiding against the UMA Spring.

In the new loop, Yusai appears in her youth as a formidable fighter before taking up negator abilities.

Rescued by Fuuko from a losing fight with a UMA, she joins Union, forced to adapt her strong iaido style to an ability that ironically forbids drawing swords.

Sean Datz (Unseen)

Sean Datz is a former gangster and Under irregular member.

He initially appears as a quest target for Union.

His power Unseen (Unseen) is self‑targeting: when he closes both eyes, his body and all items he considers his property become invisible and intangible to others.

He later implants a third eye in his forehead to bypass this downside.

In the “original” timeline he murders Fuuko during the Autumn operation.

In the altered timeline, thanks to intervention from Un Anno (see below), that assassination fails and Andy kills Sean instead.

In the new loop, Fuuko captures Sean before he plunges fully into crime.

He wanted to be an actor like his father, but Unseen caused him to vanish on camera whenever he blinked, pushing him into despair and gangs—something Fuuko helps redirect by giving him a true supporting role in their story.

Over time he learns creative expansions:

He can make trusted allies vanish with him when holding hands; he can even “erase” his own weight for movement tricks.

Backs (Unback)

Backs is a small person in a bunny costume and Under Seat 9, often referred to as “Bunny” by her comrades.

She speaks in a childish tone and adores Rip and Latla, later befriending Fuuko as well.

Her ability Unback (Unback) locks anything she covers with her costume in a state where it cannot emerge or escape.

Anything fully inside the bunny suit is effectively trapped.

Due to this power, Backs herself can never take off the suit, living a permanently costumed life.

She uses Unback as a team‑friendly capture tool, an unusual support skill among Under’s otherwise lethal roster.

Terror (Untell)

Terror is a former military communications officer and one of Billy’s earliest comrades, Under Seat 2.

He wears equipment on his back and uses an external speaker device to communicate.

His power Untell (Untell) denies all forms of communication using his own body.

He cannot speak, send Morse, walk a message to someone, or even gesture meaningfully without his body locking up.

To circumvent this, he relies on mechanical intermediaries like speakers, and he weaponizes disruptive sound and signals in battle.

In the new loop, Untell awakens in the middle of a war, nearly dooming his unit until Fuuko’s group steps in; he then joins Union alongside Billy and Creed.

Un Anno / Akira Kunou (Unknown)

Un Anno is the pen name of the mangaka hand‑drawing the in‑universe series “Reach You,” Fuuko’s favorite romance.

The real person is Akira Kunou, a man whose life is defined by invisibility.

His power Unknown (Unknown) denies recognition of his existence and actions by other beings.

People cannot perceive him, and even the side effects of his actions are subtly erased from awareness.

Akira picked up the artifact G‑Liner, a drawing pen that can manifest what it sketches.

G‑Liner was later upgraded by Apocalypse’s “Information” UMA quest reward to contain vast knowledge of past and future loops.

As a child, Akira discovered that only things created under the identity “Un Anno” could be noticed by others.

So he became a popular but mysterious mangaka, embedding future hints into his work to nudge the negators’ fate.

He survives by petty theft and slipping through society unseen, clinging to the stories of Andy and Fuuko he learns through G‑Liner.

Ultimately, his interventions around the Autumn UMA massively alter key events and save multiple lives.

Phil Hawkins (Unfeel)

Phil Hawkins is a young, androgynous boy with cybernetic limbs and Round Table Seat 4.

He is always expressionless and often sucks on his fingers like a small child.

His ability Unfeel (Unfeel) denies his own sensations and emotional responses.

This lets him handle mind‑warping artifacts safely but at the cost of a blunted or absent emotional life.

In the new loop, Phil is born on an orbiting space station as part of a shady human experiment project.

After falling ill, his brain is moved into a mechanical body, causing further distancing from his humanity.

When Unfeel awakens, it wipes away his emotions under crushing isolation, leaving only a strong desire to protect his mother.

Fuuko’s group rescues him from alien attack, returns him to Earth, and helps him join Union—where he can slowly rebuild a sense of self and belonging.

Lucy (Unhealthy)

Lucy is a frail young girl Andy encounters while searching for Fuuko.

She has never enjoyed normal outdoor life due to constant minor illnesses.

Her ability Unhealthy (Unhealthy) denies her own physical well‑being.

While she does not suffer from specific dramatic diseases, she is perpetually prone to colds, breathing issues, and general frailty.

When the UMA Ghost introduces the concept of spirits, Lucy’s strong childhood imagination—always dreaming of flying outside like Peter Pan—lets her naturally perform astral projection.

Her ghostly form becomes a vital tool against Ghost itself, tipping the scales in a metaphysical battle.

Eleven‑th Generation Yamaoka Isshin (Unbreakable)

The Eleventh Yamaoka Isshin is the grandfather of Unbreakable negator Haruka Yamaoka.

He carries the same family title and ability.

His power Unbreakable (Unbreakable) lets him forge objects that cannot be destroyed as long as his resolve and craftsmanship are sufficient.

Armor projects, however, are emotionally harder for him due to past trauma.

In the new loop, Fuuko warns him of the grim fate awaiting his granddaughter.

Determined to change that future, he joins Union earlier and becomes a key artisan ally.

Kenji Yoketsu (Unavoidable, Successor)

Kenji Yoketsu is a 98‑year‑old man living in Saitama Prefecture in the new loop.

He uses Unavoidable for petty fun, like guaranteeing himself the grand prize at lottery drawings.

Upon his death, the mantle of Unavoidable passes to Void Volks.

This transfer explains how the ability changes hosts between loops while the concept persists.

Below are some of the more important UMA referenced in the story.

Each represents a rule or phenomenon and often has multiple “phases” of power.

Move

Move is a Union‑controlled UMA resembling a cube‑faced being.

It can open warp holes and teleport people and things, functioning as Union’s intercontinental transport system.

Move is capricious but generally cooperative once captured.

Its precise rule is tied to motion, allowing for creative repositioning during operations.

Clothes

Clothes is a clothing UMA that possesses humans and transforms into the outfit they most deeply desire.

Once the host is satisfied, Clothes can seize control of their body.

Initially it escapes Union custody but is later persuaded by Andy to fuse with him instead.

It becomes his dream outfit: regenerating, durable clothes that survive the carnage of Undead battles and spare everyone from constant nudity.

Fuuko affectionately calls this UMA “Clo‑chan.”

It loves lint and fuzz, adding a strange, cute quirk to its presence.

Spoil

Spoil is the UMA of corrosion and rotting.

It imposes a countdown on anyone who enters its domain; when the timer hits zero, victims turn into zombies.

In its second phase it emits beams that disintegrate both organic and inorganic material and radiates decay in a wide area.

Spoil overran a rural American town, turning its residents before Union captured it.

Under Union’s threat, Spoil begrudgingly cooperates with Juiz’s plans in some later operations.

It is a good example of how UMA can be repurposed rather than strictly destroyed.

Galaxy

Galaxy is the UMA representing the galaxy itself.

It appears as a star‑speckled humanoid titan and arrived as a penalty for failing a quest.

The addition of Galaxy retroactively created stars, constellations, mythologies, weekdays, and even hostile aliens.

After an alien incursion that Juiz repelled, extraterrestrial contact abruptly ceased, suggesting deeper manipulation.

Galaxy’s presence underscores how dramatically a single UMA can rewrite the setting’s cosmology.

It also ties into future Master Rules and later time challenges.

Burn

Burn is the UMA of burning and fire, a giant humanoid entirely wreathed in flames.

It was originally captured by Union but later freed and courted by Under.

Burn cooperates with Under because it longs to meet its creator, Sun.

In the Winter Arc epoch, Burn becomes critical in dealing with the UMA Winter by melting catastrophic cold on a global scale.

Thirst, Insect, Gravity, Slice, Magma

These four UMA show up together in the dense UMA forest Andy explores.

Thirst desiccates everything, embodying dehydration.

Insect is a composite bug monster controlling swarms.

Gravity manipulates gravitational forces to crush or fling.

Slice imposes cutting planes; Magma spews molten rock.

Andy destroys several of them in one go, angering Sun enough to trigger a “regulation” response.

This reckless spree showcases both Andy’s raw power and the risks of nuking rules without a plan.

Seal

Seal is the UMA of sealing, a bandage‑wrapped humanoid with talismans and the self‑proclaimed “king of UMA.”

Like Ruin, he is a Regulator dispatched directly by Sun to restore balance.

Seal can extend his talismans to engulf negators and UMA, absorbing them to use their abilities himself.

He has consumed other UMA like Jewel, Splash, and Bomb.

He fails to secure Andy’s soul during the Ghost incident and is later apparently destroyed by Feng Kowloon in a single panel during Ragnarok.

Seal’s existence hints that some UMA serve as enforcement tools rather than pure “rules.”

Heat

Heat attacked Gina’s home village, burning everything to please Sun.

In the 101st loop, Fuuko uses a highly charged “Unluck shot” aged 44 years to obliterate Heat, saving the village.

Ghost

Ghost is the UMA of spirits and souls.

Its addition introduces the concept of a separable soul, altering the definition of death.

Ghost looks like a massive stitched‑together specter.

It joins forces with Ruin, kidnapping Fuuko’s disembodied soul, and sparking a spiritual rescue mission.

Thanks to Lucy’s astral projection and Andy’s desperate resistance, Ghost’s plans are foiled.

The presence of souls also allows for constructs like jiangshi and certain artifacts to work in new ways.

Information

Information is a rare quest‑target UMA caught decades in the past.

Capturing it granted the reward of embedding past and future data into any chosen artifact.

Union used this on G‑Liner, the pen Akira Kunou picked up.

This made G‑Liner a timeline recorder, seeding the story of Undead Unluck itself into Un Anno’s hands.

Seasonal UMA: Spring, Summer, Autumn, Winter

The four Season UMA are some of the most central concept‑type entities in the story.

They are tied to a massive overarching quest, with three marked for execution and one for capture.

Spring

Spring is the UMA of spring, a demon‑like figure in a kimono carrying an umbrella, speaking entirely in 5‑7‑5 verse.

It stands atop a Tokyo tower and loves traditional games and gambling.

Within its territory, anyone who touches cherry blossoms or lingers too long turns into a cherry tree.

These trees can then be weaponized to overgrow structures.

Spring’s backstory shows it once longed to befriend humans, learning games and language but being feared instead.

An encounter with the first Yamaoka Isshin and a swordsman named Tesshu inspired it to wait for a “truly cool human” to play for keeps with.

During the grand Spring quest, Spring is partially hijacked by Sun and driven berserk.

Union and Under join forces; after a brutal battle and a final Unluck‑driven dice gamble using an artifact, Fuuko wins, and Spring dies peacefully, satisfied.

Summer

Summer is the UMA of summer, initially appearing as many small insect‑like entities discovered in Taiwan.

Given enough gunpowder to consume, they merge into a colossal dragon form.

In Phase 2, Summer’s belly scales each act as cores, all of which must be destroyed at once or they regenerate.

In previous loops, no team ever fully defeated Summer.

Killing Summer erases the concept of summer’s warmth, throwing the world into an extreme winter.

In the 101st loop, Union manages to unlock new teamwork, neutralize Feng’s interference, and finally slay Summer.

Autumn

Autumn is the UMA of autumn, a giant spider that roams Stanley Park in Canada.

It slashes victims with its claws, transforming their bodies into books that chronicle their life.

Autumn delights in reading those life‑books and then devouring the people afterwards.

Even Andy’s brute force does nothing against its durable shell.

Autumn can fuse with its brood of little spiders to reach Phase 2, changing into a woman‑like figure with a seductive voice.

This form is key in a huge multi‑chapter battle that also involves Un Anno’s precognition and Under’s temporary cooperation.

In the pre‑Fuuko loop, Autumn is captured, not killed, so its concept persists.

In the changed loop, Gina Chamber manages to destroy it before full evolution, altering later events.

Winter

Winter is the UMA of winter, manifested as a gigantic ice mass atop Mount Ararat.

Billy monitors it because its activation would mean doom.

When Summer is finally slain, global seasonal balance is wrecked.

Winter surges, freezing the world and hastening an extinction‑level ice age.

As part of a desperate deal with Under, Fuuko arranges for Burn to destroy Winter.

This solves one problem but exacerbates another: the world’s orbital stability and time flow spiral out of control.

Some UMA have become Master Rules—absolute, permanent concepts that persist across loops.

Among these, ten are singled out as the Top Ten Rules, each with human‑like forms and seats at a celestial round table inside the Sun, called the Master Room.

These ten include:

Soul (Seat 1): youthful man controlling souls, firing a colossal “Soul Road” beam.

Death (Seat 2): nun‑like reaper wielding a massive scythe, whose juniors kill by touch.

Change (Seat 3): spiral‑haired woman altering objects, short‑tempered and foul‑mouthed.

Luck (Seat 4): haloed boy embodying fortune itself.

Justice (Seat 5): armored knight; fully countering this one requires Juiz’s Unjustice.

War (Seat 6): burned, hulking general summoning “Genocide Weapons” from every era.

Time (Seat 7): elderly gentleman with time‑manipulation techniques like Time Defense, whose Phase 3 form appears younger.

Language (Seat 8): girl in a Babel‑like hat, obsessed with rematching Nico after being solo‑killed in a prior loop.

Beast (Seat 9): pelt‑wearing man chaining and controlling beasts, copying their powers and giving copied abilities to enslaved creatures.

Sickness (Seat 10): refined young man fond of classical music, spreading diseases with black note‑shaped projectiles.

These Master Rules cannot be erased by killing them in a single loop.

They form the upper echelon Sun relies on to enforce and experiment with reality.

Artifacts are powerful relics created by Luna to arm humanity against Sun.

Each has unique, sometimes brutal side effects on users and often stores memories from prior loops.

Ark

Ark is the ultimate artifact, actually identical to Union’s Round Table itself.

It allows its chosen occupant to ride through Ragnarok into the next loop.

Activation requirements include:

Ragnarok must have begun.

Enough points must be held by the negator in Seat 1.

A lengthy “charging” period proportional to points gathered.

Using Ark stops the traveler’s aging, but each use pushes their starting era further into the future of the next world.

For negators like Juiz, this means gradually starting closer and closer to modern times rather than prehistoric eras.

Apocalypse (Artifact Aspect)

As an artifact, Apocalypse holds the most comprehensive memory library of previous loops.

It can display those memories as visions to selected viewers.

Unlike smaller artifacts, Apocalypse stores so much trajectory data that unprotected minds can be overwhelmed.

It is also literally tethered to Sun’s rule system via the hundred‑hole stone slab that fills one hole for each punishment enactment.

G‑Liner

G‑Liner is a pen that manifests whatever the user draws in midair.

Only one of each drawn object can exist at a time; drawing another replaces the prior one.

After receiving the Information UMA reward, G‑Liner also holds future and past data.

Akira Kunou uses it both to survive and to script the meta‑story that guides Fuuko and Andy.

Remember

Remember is the card artifact embedded in Andy’s forehead.

It has two faces: one preserves memories across a loop, the other erases them.

Each loop, only one face can be used; the choice determines whether Andy or Victor keeps continuity.

This tradeoff lies at the heart of their identity struggle.

Entruster

Entruster is a set of limb‑like artifacts worn by Phil Hawkins.

They transform emotional residue collected from prior users into raw power.

In exchange, Entruster devours the wearer’s feelings, turning them into a functional but emotionally hollow shell.

Only someone with Unfeel can use Entruster without being mind‑broken.

Death Game

Death Game is a string of beads that can convert corpses into jiangshi bodyguards.

These undead retain their memories and personalities but must always protect and obey the artifact’s owner.

It allows reuse of fallen heroes at the cost of profound ethical questions.

Feng first wields it; it later passes to Mui when she resurrects Shen.

Life Is Strange

Life Is Strange manipulates age.

When used on someone else, it ages or de‑ages them by N years while the user experiences a tenfold age change in the opposite direction.

Rip uses it to resurrect himself and to rejuvenate Feng.

Its brutal exchange rate ensures that every use warps someone’s lifespan dramatically.

Disc

Disc is a massive UFO‑like craft discovered by Union.

It can fly freely, cloak itself, and fire devastating beams.

In the 101st loop, Disc becomes a geopolitical flashpoint as nations fight for control.

Union tries to keep it out of Sun’s hands while also leveraging its firepower.

Kinto‑un and Black Cloud

Kinto‑un is a golden cloud mount that responds only to those with a “pure heart.”

It provides rapid aerial mobility and is Shen’s primary transport.

Black Cloud is a similar artifact owned by Feng.

Together they create some of the flashiest mid‑air battles in the series.

Kurikara (Unbreakable Sword)

Kurikara is one of the masterpieces forged by the Unbreakable clan.

It is a katana that cannot break as long as its creator’s fear does not compromise the forging process.

Andy uses Kurikara as his signature weapon, channeling Undead’s regenerative blasts through it.

It symbolizes the bond between him and the timid but resolute blacksmith Haruka Yamaoka.

Three Supreme Artifacts

Luna forged three Superior Artifacts capable of reaching or resisting Sun directly, collectively called the Three Heart Treasures.

Rebellion: possessed by the UMA Past as a reward clue, it forms a vengeful weapon fueled by the user’s hatred and drains their life in exchange.

Aegis: a shield that previously blocked Sun’s attacks for thousands of years; unreachable unless the world survives to at least 2020.

Jihart: the third, never found by Juiz in earlier loops; Fuuko hypothesizes it can only be reached in the 101st loop and beyond.

Aegis is eventually unearthed and used extensively during Ragnarok, tanking repeated assaults before finally shattering.

The search for Jihart becomes one of Fuuko’s long‑term strategic goals.

Ragnarok

Ragnarok is the 101st and final penalty engraved on the stone slab linked to Apocalypse.

When triggered, it heralds Sun’s personal arrival to destroy Earth.

During Ragnarok, Sun descends from the sky, assaults Ark, and unleashes type after type of catastrophic attack.

Negators and UMA alike become pawns or collateral in this last, brutal “round.”

To loop successfully, Union must protect the Round Table long enough to charge Ark and launch.

This often means sacrificing countless allies and confronting top‑tier Master Rules directly.

Loops as Time Warps

Technically, a loop is a forward‑only time warp to the next reconstructed Earth after it is shattered and reformed.

Negators who ride Ark or possess Undead survive the interim void and early volcanic ages.

Each loop begins at a later point in planetary history for Ark riders.

Early on, Juiz started in the dinosaur era; by the 101st loop, she emerges in the 1800s.

Most people are not “reincarnated” one‑to‑one but are reborn as similar individuals with variations.

Memories generally do not persist, but artifacts and certain UMA store echoes of past cycles.

Points

Points are an invisible currency earned by completing quests and defeating UMA.

Mortals cannot sense them, but they accumulate on each negator.

A minimum point threshold is required to ride Ark.

Points can be transferred between negators, and they can be spent to request limited favors from Luna and Sun.

At the climax of one loop, Victor transfers his entire point balance to Fuuko, promoting her to Seat 1 and granting her the right to lead the next loop.

This single choice reshapes the strategy of the subsequent world.

2025 Winter Special: Undead Unluck – Winter Arc

A new animated installment, Undead Unluck: Winter Arc, was announced for winter 2025.

It is a one‑hour TV special focusing on the Winter UMA storyline and later conflict beats.

The special is produced by E&H production with development cooperation from david production.

Notably, it is directed, storyboarded, and episode‑directed by Sung‑ho Park, known for dynamic action direction.

Core staff:

Director: Sung‑ho Park

Script: Takeshi Aoshima

Character designs: Hideyuki Morioka and Shunichi Ishimoto

Music: Kenichiro Suehiro

Animation production: E&H production

Queen Bee returns to perform both the special’s opening song “01” and a new ending theme “02.”

The special will air across the full TBS network, followed by satellite rebroadcast and streaming on major platforms.

Undead Unluck received strong early praise for its inventive premise, brisk pacing, and emotional payoffs.

It captured first place in the Next Manga Award 2020 (Comics Division) and ranked in the 5th TSUTAYA Comic Awards in 2021.

Influential creators like Kinoko Nasu and various illustrators, as well as comedian Sunshine Ikezaki, provided endorsement blurbs on volume wraps.

By late 2022 the series surpassed 1.8 million copies in circulation, with further growth during and after the anime broadcast.

The franchise has branched into light novels under Jump j Books, exploring Union’s daily life, romantic side stories, and even alternate high school AU scenarios.

Promotional collaborations have included tie‑ins with major chains such as a sushi restaurant campaign featuring Fuuko’s in‑store announcements and themed merch.

Undead Unluck’s charm lies in how it balances absurd humor, gore‑slapstick, and heavy tragedies within a tightly interlocking rule system.

At its heart, though, it is always the story of a girl who thought she could never touch anyone, and the undead idiot who insisted that made her the one person who could save the world.
