Ryuu is introduced in the main story as a quiet, strict waitress working and living at the tavern Hostess of Fertility, hiding her past as the famed adventurer “Gale of Astraea.”

She once belonged to the Astraea Familia, gaining a fearsome reputation as a level 4 adventurer who fought through Orario’s “Dark Age,” and later performs the unprecedented feat of ranking up from level 4 to level 6 in one jump before the Faction War.

Even after her “retirement,” her combat power barely declines, so Hermes frequently drags her into incidents as a temporary helper tied to the Hestia Familia and Hermes Familia.

After the conclusion of the Faction War against the Freya Familia, she formally joins the Hestia Familia and returns to active adventuring.

Within the series Ryuu is one of the most popular characters and effectively functions as a third main heroine alongside Ais Wallenstein and Hestia.

She is also the main protagonist of the spinoffs Astraea Record (set seven years before the main story) and Familia Chronicle: episode Ryuu.

Appearance

Ryuu has a classic elf beauty: fine, well‐sculpted features, sky‐blue eyes, and a slender, athletic body.

At the start of the main story she wears her light green short bob; this color is actually dyed to hide her identity, while in the Astraea Familia era her natural hair was long blonde.

She is flat and slender enough that she lacks confidence in her figure, especially compared to more voluptuous heroines.

As time passes and her “stopped” life begins to move again, she lets her hair grow, eventually dyeing it back to its original blonde and tying it in a ponytail reminiscent of her late captain Alise.

Personality

Ryuu is stern, upright, and almost overly serious.

Her speech is formal and often harsh, but she softens slightly around people she trusts.

On the surface she is calm and largely expressionless, speaking only when needed.

Underneath, she is an intense emotional type who shows no mercy to enemies and is driven by a strong sense of justice.

Her kindness and justice are genuine: she often throws herself into trouble for the sake of others, at obvious cost to herself.

However, she is extremely clumsy outside combat—her cooking becomes charcoal, and during morning training she tends to beat Bell Cranel until he passes out, only realizing later that she overdid it.

Ryuu herself admits, “I always go too far,” and this combination of seriousness and clumsiness frequently leads to “broken” behavior that makes others call her a “clumsy elf.”

She also struggles with her own internalized elf prejudices; despite hating her homeland’s elitist racism, she sometimes catches herself thinking similarly and despises herself as a “vile elf no different from them.”

Culturally, elves avoid skin contact with those they have not accepted, and Ryuu is no exception: if someone unfamiliar suddenly tries to touch her, she reflexively slaps their hand away.

The only people who could take her hand on first meeting were Alise, Syr Flover, and Bell Cranel—each of whom ended up giving her a “home.”

Notably, unlike most elves, Ryuu does not harbor hatred toward the Crozzo magic swords, weapons that once burned many elf forests; she is unusually flexible for her race.

Romantic View

Ryuu’s notions of romance are extreme and somewhat deranged in their purity.

She seriously believes that when a man and woman start dating, they should first go alone into a silent forest at night and swear their eternal love to the moon.

In her mind, lovers must not even hold hands until a marriage promise is made and vows are exchanged in the elf fairy forest.

Even other elves consider this absurd; Alfia and Alicia in other media note that Ryuu’s values are rare and frankly frightening even by elf standards.

Ironically, despite these strict ideals, in the story she ends up warming Bell naked in the deep floors to stave off hypothermia and confessing to him in the middle of a life‐and‐death battle broadcast across Orario.

Her actions routinely betray her own “chaste” doctrine.

After the deep floor incident, Ryuu becomes so aware of Bell that she can barely look him in the face.

She struggles to understand these new feelings, but during the Faction War she finally articulates them and confesses her affection.

Childhood and Leaving the Forest

Ryuu was born in the Forest of Lymirua, into a family of “Guardians of the Great Sacred Tree,” elite warriors raised from childhood to defend the forest.

She spent her early years training and even joining adults in combat when enemies attacked.

Lymirua’s elves were extremely proud, even by elf standards, and especially contemptuous of other races.

Watching their constant elitism, Ryuu began to suspect that elves might be the truly ugly ones, and the disgust she felt for her own people grew with age.

At around 11 years old, unable to endure the hypocrisy and racism around her, Ryuu fled her home.

She set off for Orario, the “Center of the World,” hoping to find companions who could respect each other regardless of race.

Arrival in Orario and Joining Astraea Familia

Arriving in the outside world for the first time, Ryuu was overwhelmed.

Her elf instinct to reject touch made integration difficult; she reflexively knocked away anyone who approached, leaving her isolated.

This left her vulnerable in Orario’s Dark Age, when crime and human trafficking were rampant.

She was targeted by Jura and his cohorts, nearly being sold into the pleasure district, but was saved at the last moment by Alise.

As they talked, Ryuu warmed to Alise’s bright, positive personality.

When Alise invited her to join the Astraea Familia, Ryuu accepted, finally gaining the mutually respectful comrades she had longed for.

Ryuu’s talent blossomed quickly.

Even considering that the anti–Evilus war generated abundant “achievement” experience, she still climbed to level 4 within just three years, earning the nickname “Gale Ryuu Lion.”

The Dark Age, Juggernaut, and Revenge

For a time Ryuu enjoyed peaceful days with Astraea Familia.

Five years before the main story, however, the Evilus faction Rudra Familia triggered a large‐scale dungeon collapse, summoning the catastrophe known as Juggernaut.

Juggernaut slaughtered Ryuu’s comrades one after another.

Alise, Kaguya, and Lyra died protecting her, leaving Ryuu as the sole survivor.

Blaming Evilus and herself, Ryuu swore revenge.

Knowing the path she chose would destroy her, she nevertheless pushed her goddess Astraea to leave Orario, begging her to depart so that Ryuu could stain herself with blood without tainting Astraea.

She then went on a brutal vendetta.

Out of control, she slaughtered not only Evilus members but anyone even tangentially connected—merchants, corrupt guild officers, anyone who cooperated with them.

Her rampage ironically helped end the Dark Age, as Evilus was annihilated.

But the means were too extreme: Ryuu was branded a wanted criminal by the Guild, stripped of her adventurer status, and placed on the blacklist with a bounty on her head.

Collapse and Rescue by Syr and Mia

After her revenge, Ryuu felt no satisfaction, only emptiness.

Exhausted and bleeding out in a back alley, she lay waiting for death.

There, Syr Flover happened to pass by and offered her hand.

Syr and the tavern owner Mia Grand nursed her back from the brink.

Ryuu, having lost the will to live, was openly nihilistic.

Syr and Mia refused to let her die; Mia forcibly “hired” her at the Hostess of Fertility and essentially conscripted her into work, backing this up with the fact that Mia was physically stronger and Ryuu could not win.

To further conceal her identity from pursuers and the public, Syr dyed Ryuu’s long blonde hair light green.

At first, Ryuu’s ineptitude caused constant accidents in the tavern, drawing harsh scolding from Mia, yet these busy days gradually kept her from drowning in grief.

The Guild, including its god Uranus, knew where she was but turned a blind eye because Astraea Familia had greatly contributed to Orario’s safety.

Under the condition that no one reveal information about Juggernaut, they decided not to prosecute Ryuu, though her blacklist status remained on record.

Syr eventually thanked Ryuu for ending the Dark Age, giving meaning to her actions and offering “a reason to live.”

In response, Ryuu resolved to watch over Orario in place of her fallen comrades, and to repay Syr’s kindness by working at the tavern.

Meeting Bell Cranel

Ryuu first interacts with Bell Cranel when he starts frequenting the Hostess of Fertility.

Because Bell is Syr’s crush, Ryuu begins to keep an eye on him and even arbitrarily “decides” that Bell will be Syr’s future partner, silently rooting for Syr.

Seeing Bell as a greenhorn, she scolds him often but also advises him on adventuring basics, drawing on her experience.

She respects Bell enough to call him “a human worthy of admiration,” a rare compliment from her.

The Middle Floor Search and Goliath

When Bell and his allies vanish in the middle floors after being used in a “Monster Parade” by the Takemikazuchi Familia, Hermes requests Ryuu’s help for the rescue team.

She helps escort Hestia and Hermes down toward the 18th floor “Under Resort,” casually destroying middle‐floor monsters along the way.

They find Bell’s group in the safe area, but to avoid revealing her identity, Ryuu withdraws and acts alone in the forest.

While bathing in a secluded river, she is accidentally seen by a passing Bell; once she confirms it was an accident, she forgives him.

She then leads Bell to the Astraea Familia’s makeshift grave in the 18th floor forest and shares her past, revealing the truth behind her “retirement.”

Later that night she joins the battle against the massive variant Black Goliath.

Ryuu’s level 4 combat ability is top tier; she outperforms nearly everyone on the field.

She buys time for Bell to fully charge his skill Argo Vesta and, according to Liliruca Arde, would have claimed almost all the experience for the kill if the system allowed.

War Game Against Apollo Familia

Soon after returning to the surface, Hestia Familia is forced into a War Game with the Apollo Familia.

Because of the difference in numbers, the gods grant the special rule that the Hestia side can recruit one external helper.

Hermes again asks Ryuu to join, and though she laments being treated as a convenient handyman, she accepts due in part to Syr’s pleading and her own inability to abandon Bell.

During the assault on Apollo’s fortress, she wields a Crozzo magic sword crafted by Welf Crozzo, devastating enemy forces.

Even when over half of Apollo Familia’s troops concentrate on her, she dismantles them with ease, defeating squad leaders such as Lissos and paving the way for Bell’s victory.

Xenobos (“Xenos”) Incident

When Hestia Familia returns to the 19th floor to investigate where they met Wiene, Ryuu escorts them as far as the 18th floor.

She notices Bell’s confusion about monsters after meeting Wiene and offers to listen whenever he is troubled.

Later, when the abused intelligent monsters known as Xenos revolt in the city, Ryuu joins forces with Aisha Belka, Asfi Al Andromeda, and others to help contain the chaos and support Bell.

She attempts to convince Bell to return to safety, but respects his decision when he chooses to chase after the Xenos.

At the 18th floor, she confronts Asterius, the strongest Xenos.

Despite her strength, she is utterly overpowered and defeated, showing the terrifying gap between them.

Days later, Asfi informs her of the Xenos and the existence of the manmade labyrinth Knossos, and requests her cooperation in exchange for information on Evilus.

Concerned for Bell and eager to end the lingering threat of Evilus remnants, Ryuu agrees to help.

During the infiltration of Knossos, she fights Ais Wallenstein to buy time, boosted to level 5 by Haruhime Sanjouno’s level boost magic.

Even with superb technique and terrain use, the gap in level and experience proves too much; she holds Ais back for only about three minutes.

Second Encounter with Jura and Juggernaut’s Return

During the first Knossos assault, Ryuu spots her old enemy Jura and chases him into the dungeon, separating from the main force and entering the lower floors.

In the dungeon’s watery labyrinth, she discovers that Jura intends to summon Juggernaut again.

Determined to prevent the catastrophe at any cost, she brutally defeats the pursuit team that came after her and corners Jura.

There she meets Bell, who has been following to clear her of a murder accusation Jura engineered in Rivira.

Ryuu tries to drive Bell away to protect him, but Bell insists on helping, believing in her innocence.

Grateful yet ashamed, she apologizes and fights alongside him against Jura’s tamed monster, the Worm Whale.

They defeat the Worm Whale, but Jura’s allies trigger large explosions, forcing Juggernaut to be reborn.

Sensing its presence, Ryuu trembles in terror, desperately attempting to get Bell to flee, but Juggernaut appears before them and begins a new massacre.

Bell is gravely injured trying to stop it, and Ryuu uses her healing magic to stabilize him.

She then tries to hold Juggernaut off alone to save the last survivor, Bors, only to be quickly maimed, her leg broken.

At the last moment, Bell drinks the healing Mermaid’s Blood provided by Marie, recovering fully.

He reengages Juggernaut, exploiting what he learned in their first encounter and managing to destroy its right arm with Argo Vesta.

Jura temporarily gains control of Juggernaut with a magic tool, but the monster rejects being controlled and instead kills Jura.

Before Ryuu and Bell can process this, the dying Worm Whale hears Jura’s last command to “kill Ryuu and Bell” and swallows both, dragging them into the deep floors.

Survival in the Deep Floors

Bell cuts them out of the Worm Whale, only to discover they’ve fallen into the 37th floor, infamous as one of the dungeon’s most lethal zones.

Both are badly wounded, with no supplies, but Ryuu uses her earlier exploration experience as a guide.

They aim for a route to higher floors but must cross the Colosseum, a place where monsters continuously spawn.

Ryuu decides to sacrifice herself to give Bell a chance: she ejects him from the arena with her magic and seals off her retreat, choosing to fight alone to the end.

Overwhelmed and moments from death, she is saved when Bell returns instead of fleeing.

Using a large cache of flame stones amplified by Argo Vesta, Bell detonates the Colosseum, destroying the horde and miraculously surviving by shielding Ryuu.

The explosion reveals an uncharted area that turns out to be a rare deep‐floor safe zone.

They rest, recover slightly, and continue upwards, but Juggernaut ambushes them again, now obsessively hunting them.

Exhausted and terrified, Ryuu collapses unconscious during the battle.

In her dreams she meets the spirits of her Astraea Familia comrades, who encourage her to live and carry on their justice.

Awakening with renewed resolve, she fights alongside Bell in a final showdown.

She uses her Luminous Wind magic in innovative ways, using its recoil to perform aerial maneuvers, high‐speed jumps, and complex trajectories, eventually delivering a finishing technique “Starflower” (directly striking Juggernaut with a light orb) that allows them to defeat it.

Both collapse afterward, but are rescued by the Xenos and later returned to the surface.

Bors, feeling indebted to Ryuu for saving him, tells the Guild that she died in Jura’s incident, giving her a clean slate on paper.

This deep‐floor ordeal is also where Ryuu’s feelings for Bell crystallize into clear romantic love.

From then on she becomes a “lovestruck clumsy elf,” much more easily flustered where he is concerned.

Orgia Saga and the “Orgias” War

A short time after returning, the city faces the final showdown with the “Destroyer of the City,” Enyo, in the Orgia Saga.

Ryuu joins the battle at Hermes Familia’s request.

Guided by Lulune she reaches the front lines where Bete Loga and Lefiya Viridis are fighting.

With Haruhime’s level boost, she teams up with Aisha and Asfi to battle the monstrous Ain, a level 7 equivalent foe.

The battle is grueling, but through combined effort and sacrifice they eventually manage to defeat Ain.

Goddess Festival and Freya’s Breakdown

During Orario’s autumn Goddess Festival, Syr decides to invite Bell on a date.

Ryuu, now secretly in love with Bell herself, inwardly hates the idea but chooses to prioritize Syr’s happiness and supports her.

On the day itself, she ends up tailing the couple with colleagues Anya, Chloe, and Runoa.

When they follow Bell and Syr onto a ship restaurant, they disguise themselves as staff, but the date is interrupted when Freya Familia members storm the ship to retrieve Bell.

Ryuu joins the fight to protect Syr, but loses track of the pair amid the chaos.

Bell later reveals that he rejected Syr’s confession, saying he loves someone else, and that the “Syr” attacked later by Freya Familia was a fake.

Unable to reconcile her feelings yet unwilling to blame Bell, Ryuu decides to help find the missing Syr.

However, Syr—revealed to be Freya all along—snaps from Bell’s rejection, loses her restraint, and overwrites Orario’s memories, altering reality so that everyone believes Bell has always been a member of Freya Familia.

Ryuu and Bell are knocked out by Ottar, but Asfi manages to carry Ryuu out of Orario.

Because she awakens outside the influence of Freya’s charm, Ryuu remains one of the few who remember the truth.

She and Asfi infiltrate the transformed Orario and confront Syr/Freya.

Syr coldly reveals that all their time together at the Hostess was “just play” and her identity as Freya, then offers to share Bell with Ryuu, fully indulging in lustful, twisted behavior.

To Ryuu, this is not the Syr she loves but a monstrous presence wearing her face, and she slaps her hand away.

Immediately, Ryuu is subdued and imprisoned in the Freya Familia stronghold Folkvangr, with cursed shackles that weaken her stats and seal her magic.

After a week of captivity, Horn secretly visits Ryuu and offers to help her escape, on the condition that Ryuu cause a distraction on the fortress’s east side.

Sensing Syr’s presence in Horn, Ryuu decides to trust her and complies.

She escapes her cell and fights through Freya’s forces even in her weakened state, but once again is cornered by Hegni.

Just as he is about to defeat her, Hestia uses her divine authority to purge Freya’s charm from the city, and Ais storms Folkvangr to rescue Bell; Ais arrives and saves Ryuu from Hegni.

Faction War and Joining Hestia Familia

With Freya’s control broken, she demands a War Game with Hestia Familia, staking Bell’s conversion as the prize.

This escalates into the massive Faction War, a clash between the Freya Familia and an alliance led by the Hestia Familia.

To help Bell and stop Syr’s madness, Ryuu decides to join the war.

She travels to the Sword‐Making City Zoringhen to reunite with her goddess Astraea and receive a status update.

In the inn “Rest of the Stars,” she meets Astraea for the first time in five years and is warmly welcomed, the goddess sensing that Ryuu’s “journey has ended.”

Her updated status shows that she has reached level 5, with the new skill Justice Succession manifesting at her level 5 rank up.

Astraea then reveals that if she fully unlocks Ryuu’s accumulated excelia, she can actually boost Ryuu directly from level 4 to level 6, but that doing so at once would risk severe damage and months of adjustment.

Instead, they choose a staged approach: first unlock to level 5, train, then unlock to level 6 once Ryuu’s body and mind are sufficiently aligned.

Ryuu trains in Zoringhen with her juniors of the second Astraea Familia and with the mid‐class spirit Yufie in the local forest.

She also acts as a senior mentor, passing down experience and advice.

After receiving word of the Faction War schedule from Hermes, she has Astraea perform a final update, unlocking the remaining excelia and raising her to level 6 while granting her the Astraea Record magic, which lets her inherit and cast the magic of her ten fallen comrades.

As proof that her time has started moving again, she has her hair dyed back to blonde and ties it in a high ponytail resembling Alise’s.

Equipped with the new battle dress “Spirit Raiment” and the star blade “Alvs Justitia” forged by her successor Cecil Blackliza, Ryuu heads for the ruined city of Orza, where the Faction War is held.

On the journey, Astraea gently suggests that Ryuu leave her side and find a new place to belong; remembering Alise’s and Alfia’s words, Ryuu accepts that it is time to move on.

Battle with Hegni

Arriving late to the Faction War, Ryuu intercepts Hegni as he crushes the alliance forces.

Now on equal footing as fellow level 6 fighters, she fights him to a standstill.

When Freya Familia troops encircle them, Ryuu activates Astraea Record and calls forth Alise’s flame enchantment magic “Agaris Alvesins”, donning a burning armor that amplifies her offense and mobility.

She blasts through the encirclement, wiping out the soldiers.

Through “Divine Mirrors” broadcasting the war, Orario’s citizens witness Ryuu’s heroics.

Recognizing the return of Astraea Familia’s justice, they cheer in the streets.

Ryuu then duels Hegni again.

Heavily worn down from fighting the alliance earlier, he cannot withstand her relentless assault, and she finishes him with “Flameflower,” detonating the flame armor to defeat him.

Final Battle with Ottar

After defeating Hegni, Ryuu rushes to the battlefield where Bell is facing Ottar alone, thanks to Hedin Selland’s secret betrayal on their behalf.

She apologizes for her late arrival and heals Bell, who is badly wounded.

Even as a new level 6, Ryuu can see that Ottar, the “Strongest Adventurer in the City,” is beyond her.

At that moment, Mia Grand arrives and joins the fight to stop her old comrade.

While Mia holds Ottar off, Ryuu finishes healing Bell.

Knowing Syr confessed to Bell, Ryuu decides she cannot remain silent and confesses her own feelings to him before entering the fray—this confession is broadcast live across Orario via the Divine Mirrors.

Together, Ryuu, Bell, Mia, and later Hedin face Ottar.

Even boosted by Haruhime’s level up magic, they struggle, especially after Ottar uses “Beastification” to reach level 8–equivalent power.

In a climactic sequence, Bell finally succeeds in disrupting Ottar’s stance, creating an opening.

Ryuu’s Luminous Wind, Mia’s brutal punches, and Bell’s fully charged Argo Vesta strike home in succession, finally toppling Ottar and securing victory for the alliance.

Saving Syr and Aftermath

Freya Familia loses; the gods decree Freya’s familia disbanded and Freya exiled from Orario.

Hestia, however, offers mercy: Freya cannot remain as a goddess, but as Syr, a “daughter,” she may stay.

Freya, ashamed, is ready to leave anyway.

Before she can, Ryuu, the Hostess girls, and Bell confront her.

Seeing Syr in tears apologizing, Ryuu slaps her hard and shouts that apologizing is not enough, that she will never forgive her—but that Syr must stay with them forever, forcing their bond to continue instead of running away.

Bell pledges to remain Syr’s “knight,” watching over her so she never strays again.

Overwhelmed, Syr drops her pretense and cries out her true wish: “I want to quit being a goddess and stay by everyone’s side as Syr.”

She chooses to remain at the Hostess of Fertility as a mortal girl, and Ryuu’s words help redeem her.

After escorting Astraea and the second Astraea Familia back to Zoringhen, Ryuu formally severs her contract with Astraea, as they discussed on the road.

She chooses to start anew and, upon returning to Orario, asks Bell and Hestia to join the Hestia Familia.

Hestia happily accepts, though she becomes far warier of Ryuu’s undisguised affection for Bell.

The Guild restores Ryuu’s adventurer registration—motivated both by her role in ending the Dark Age and by not wanting to waste such a valuable level 6—but under a new adventurer name since “Ryuu Lion” is officially listed as dead.

Ryuu proposes “Ryuu Cranel,” borrowing Bell’s surname, but Hestia vehemently vetoes it.

They settle on “Ryuu Astraea,” labeling her a suspicious “newcomer” level 6 adventurer with a paper‐thin cover identity.

Although supposedly trying to hide, neither Ryuu nor anyone else really expects this to fool enemies, and indeed people who bear grudges against her appear from time to time.

However, by Hestia’s orders, former Freya Familia elites (now under Hestia’s banner as subordinates through Syr’s “subordinate god” status) serve as bodyguards and annihilate any would‐be avengers.

Ryuu still loves the Hostess of Fertility, so whenever the Hestia Familia is not exploring, she continues to help at the tavern as a part‐time waitress.

Her morning sparring with Bell now faces competition from Hedin, whom Bell also asked for training; Ryuu is dismayed at first, but they ultimately share the role while constantly bickering over training methods.

Meeting the Xenos and the Reborn Juggernaut

Not long after joining Hestia Familia, Ryuu and Bell receive a letter from Fels, Uranus’s agent, asking them to come to the uncharted area they discovered on the 37th floor.

Hestia Familia alone is still under‐leveled for deep floors, but Syr arranges for Hedin, Hegni, and the Gulliver Brothers to accompany them as an “adventurer commission.”

Even on a return trip to the site of their near‐death, Ryuu retains her strict training methods, pushing Bell hard.

Hedin demands, as payment for his escort, a sacred book from Ryuu’s homeland Lymirua, causing her to scowl but ultimately agree.

Reaching the uncharted area, they meet Wiene and the other Xenos face to face.

Despite being monsters, the Xenos display clear intellect and emotion, and Ryuu feels none of the usual elf revulsion toward them.

She learns from Fels that the Juggernaut they defeated in the deep floors has been reborn as a Xenos.

Fels summoned them to discuss what to do with such a powerful and intrinsically violent creature.

Ryuu’s feelings are complex; Juggernaut destroyed her family once and nearly killed her again.

Yet when Bell insists on trying to find a path other than mutual slaughter, she respects his wish and agrees to spare the reborn Juggernaut, choosing to watch and see what kind of “justice” its second life will bring.

Orariopiade and the Rescue of Loki Familia

When the traveling educational institution “Academy” returns to Orario, a dispute breaks out after the Guild forcibly seizes orichalcum from the students.

Angered, they stage a “student struggle,” souring relations between Orario and the Academy.

To settle this, the gods organize the Orariopiade, a representative tournament between Orario and the Academy.

With Loki Familia off on an expedition and the disbanded Freya Familia barred from participating, Ryuu is effectively the only available level 6 on Orario’s side and is inevitably dragged in.

In the three‐person water battle of the fourth round, Ryuu teams with Asfi and Aisha.

They annihilate the Academy teacher team in about a minute, leaving the spectators stunned at the overwhelming gap in power.

Later, when Loki Familia members such as Ais go missing around the 60th floor, a rescue mission is organized.

Ryuu, Bell, and Haruhime form the core of one rescue group, receiving a “Sword” command card to act as the main offensive team.

On the 28th floor, Cassandra Illion begs Ryuu to accept a “white cloth long object” for Bell’s sake; though confused by Cassandra’s prophetic but cryptic explanation, Ryuu accepts because Bell also urges it.

This item turns out to be a white silver longsword with the unbreakable property Durandal, vital in later battles.

On the 51st floor, a “floor skip” bombardment separates Bell from the main party, and Ryuu regrets hesitating to chase him after Lefiya left first.

Following Hedin’s instructions to split the group to reduce risk, she joins Raul Nord and “Leon” (a fellow supporter) on a detour.

On the 54th floor she and Leon save Xenos warriors Fear and Rett from a demi‐spirit hydra.

Ryuu easily crushes the creature, demonstrating that she is now powerful enough to swat aside foes that would terrify lower‐level adventurers.

On the 58th floor, a massive bombardment from a hydra‐type demi‐spirit tears the dungeon apart and summons yet another Juggernaut.

When Hayes attempts to capitalize on it, Ryuu uses Cassandra’s white longsword—now revealed as an unbreakable Durandal—to defend against the monster’s attacks and then borrows Bell’s Goliath Scarf as a shield.

Despite being a deep‐floor Juggernaut—far stronger than the previous ones—Ryuu, now level 6 and intimately familiar with its attack patterns, manages to defeat it solo, though at the cost of heavy physical and mental exhaustion, including broken bones beneath the scarf.

Later, at the 60th floor’s deepest point, Ryuu and the others arrive to find Bell’s group nearly annihilated by the Corrupted Spirit and the Spirit Dragon.

She uses Astraea Record to call forth the magic of her comrade Ryana Reets, a magical flame that reduces the opponent’s magic power, weakening the Spirit Dragon enough that their allies can at least survive hits.

Even weakened, the Spirit Dragon maintains overwhelming strength, and the combined forces struggle desperately.

Finally, reinforcements arrive—Leon and Ottar—and through a final all‐out effort, Bell slays the Corrupted Spirit and rescues Ais, bringing the crisis to an end.

When they return to the surface, a comedic scene unfolds as Horn tackles and pins Bell in joy, only to provoke a jealous outburst from Liliruca and Ryuu.

Bell Cranel

Bell is Ryuu’s love interest and, in many ways, her emotional savior.

Alise once teased that “if a man ever manages to hold your hand, that’s your destined one—never let him go,” and Bell indeed becomes that man.

Initially Ryuu notices Bell because of Syr’s crush and labels him a worthy human.

After the deep floor ordeal—where Bell repeatedly risks his life to protect her and help her confront Juggernaut—her feelings deepen into clear romantic love.

She mentors him in combat, often brutally, and becomes one of his main trainers alongside Ais and Hedin.

In contrast to Ais (who leads him from ahead) and Hestia (who supports him from behind), Ryuu is often described as the partner who walks at his side, sharing joys and hardships.

In the “branch history” Fairy Branch Story, an if‐route where they become a couple in the deep floors, Bell’s story shifts from a tale of one‐sided admiration to one of mutual love and adult growth.

In the main timeline, however, their relationship remains unresolved but heavily hinted as a true heroine route, especially after Ryuu’s public confession in the Faction War.

Syr Flover

Syr is Ryuu’s savior, benefactor, and closest friend, as well as secretly the goddess Freya.

She is the second person ever to hold Ryuu’s hand and the one who gave her a new life after her suicidal revenge.

Ryuu chooses to work at the Hostess to repay Syr’s kindness, calling her a dear friend even after learning her true identity as Freya.

Their bond is strong enough that Ryuu refuses to abandon her, even after the goddess’s catastrophic mistakes.

In the aftermath of the Faction War, Ryuu’s refusal to “forgive” Syr is actually a demand that Syr stay with them and atone by living together, symbolizing a deeper forgiveness than words.

Syr, for her part, admits that she both loves Bell and loves Ryuu, and in the branch history she blesses the couple, vowing to take Bell’s side only after Ryuu is gone.

Astraea

Astraea is Ryuu’s beloved first goddess and the embodiment of justice in her life.

Ryuu drove Astraea away before starting her revenge, a decision that haunted her for years.

Their reunion in Zoringhen is gentle and healing: Astraea welcomes Ryuu as someone who has finally “finished her journey.”

She updates Ryuu’s status, guides her emotionally, and ultimately encourages her to leave the nest and join the Hestia Familia.

Even after Ryuu’s formal “conversion,” their trust does not disappear; they promise to keep in touch, and Ryuu’s new adventurer surname “Astraea” testifies that she will always be Astraea’s child in spirit.

Alise Lovell

Alise is the first person ever to hold Ryuu’s hand and the captain of Astraea Familia.

She rescues Ryuu in Orario, invites her into Astraea Familia, and becomes the “sun” that leads her forward.

Alise’s leadership and optimism deeply shape Ryuu’s concept of justice and heroism.

Many of Ryuu’s inherited techniques and magic through Astraea Record, such as her flame armor, come directly from Alise.

Kaguya and Lyra

Kaguya is a ruthless realist within Astraea Familia and Ryuu’s sparring rival.

Their philosophies clash, leading to frequent fights, but their compatibility in battle allows them to learn each other’s techniques.

Lyra is the intelligencer of Astraea Familia and the sharpest thinker in the group.

Ryuu often relied on Lyra’s teachings, particularly her advice: “Change knowledge into wisdom,” a maxim Ryuu later passes to Bell.

Both die protecting Ryuu from Juggernaut, and their magic and skills live on through Astraea Record.

Ardi Varma and Shakti Varma

Ardi Varma, from another faction, is a close friend of Ryuu and dies in the Dark Age conflict.

Her words “Justice revolves” inspire the name and effect of Ryuu’s skill Justice Succession, which echoes Ardi’s own skill Justice Cycle.

Ardi’s sister Shakti Varma is a commander of the city’s guards and a comrade from the Dark Age.

Ryuu respects her as a rational, strongly principled warrior, and Shakti still calls her by her old surname “Lion.”

Mia Grand

Mia is the dwarf owner of the Hostess of Fertility, effectively Ryuu’s “Mom Mia.”

Despite traditional elf–dwarf incompatibility, Mia’s strength and big heart earn Ryuu’s respect and affection.

She forcibly keeps Ryuu alive by making her work in the tavern and constantly scolding her.

In the Faction War she reveals her own legendary past and fights Ottar herself to defend Syr, showing that Ryuu’s “mother” is one of the world’s strongest.

Asfi Al Andromeda

Asfi is Hermes Familia’s commander and one of Ryuu’s oldest friends.

They met during the Dark Age, sharing the common burden of being serious people dragged around by troublesome deities.

They frequently cooperate on covert missions and share a mutual trust that allows Asfi to risk her life removing Ryuu from Freya’s charm field.

Asfi still calls her “Lion,” reflecting their long history.

Aisha Belka

Aisha is an Amazoness warrior with whom Ryuu has a “bad but good” relationship.

Ryuu’s prudish seriousness contrasts sharply with Aisha’s unabashed lust, leading to frequent verbal clashes.

However, they respect each other’s battle prowess and often fight side by side in major crises.

Both also act as rough older‐sister figures to Bell, though in very different ways.

Hedin Selland

Hedin is another elf who trains Bell, about fifty years older than Ryuu.

After the Faction War he joins Bell’s morning training rotation, igniting a rivalry with Ryuu over who gets to be Bell’s main mentor.

They clash constantly over training philosophies and methods, but their combined guidance pushes Bell to ever higher heights.

Their dynamic is often comedic—two elite elves arguing over their favorite human pupil.

Ais Wallenstein

Ais shares many parallels with Ryuu and is both rival and ally.

Both specialize in speed and burst power, wield wind‐element magic, and have stats focused on Dexterity, Agility, and Magic.

They are also both prodigies with extremely rapid level ups, hot tempers when angered, and awkwardness outside battle, with mother‐figure mentors of near world‐class strength.

Both reach the threshold for level 6 advancement after the 37th floor deep‐floor adventure, and both begin healing from their trauma through Bell’s influence.

They first cross paths during the Dark Age due to a misunderstanding, but their duel is cut short by Riveria Ljos Alf’s intervention.

They fight again during the Xenos incident, where Ais’s greater level and experience give her victory; the author jokingly calls this showdown a “legal wife war.”

Once Ryuu no longer needs to hide her identity, she openly talks with Ais about their journeys.

For the first time, they converse peacefully outside battle, and both claim the title of Bell’s “master” while sparking a friendly rivalry.

Overall Style

Ryuu fights as a magic swordsman, combining high‐speed melee with parallel casting of long‐chant magic.

She typically wields a wooden blade or twin kodachi in melee, using her speed to dance through enemy lines while functioning as a mobile artillery platform.

Her parallel casting is so refined that some consider it on par with or surpassing even Riveria Ljos Alf, Orario’s greatest mage.

She also uses healing magic, making her a true all‐rounder capable of offense, defense, and support.

Her stats emphasize Dexterity, Agility, and Magic, which she can push into the S rank range.

In raw talent, the author has compared Ryuu and Ais as “SSSR” tier in a gacha game metaphor—essentially the highest class of prodigy.

At level 6 with Astraea Record, Ryuu can deploy buff, attack, healing, and defense magic from ten different casters, giving her unparalleled versatility.

Her skill Justice Succession further amplifies the power of any ally sharing the same god‐blood, making her a moving power multiplier for her entire familia.

Skills

Fairy Serenade

A skill that amplifies the effects of Ryuu’s magic.

Its buff is even stronger at night.

Mind Load

A skill that boosts Strength when Ryuu consumes her Mind while attacking.

She can control whether it activates and how much Mind it burns.

Aero Mana

A skill that increases attack power in proportion to Ryuu’s running speed.

The faster she moves, the harder she hits.

Justice Succession

A level 5–onward skill that strengthens the skills and magic of all allies within range who share the same divine blood as Ryuu (that is, fellow Astraea or, after her conversion, fellow Hestia Familia members via her goddess link).

It increases their Magic and Mind, grants medium resistance to mental interference, and also applies to Ryuu herself; its magnitude and radius scale with her level.

This skill mirrors her late friend Ardi Varma’s Justice Cycle in both name and effect, symbolizing that Ardi’s justice lives on through her.

Development Abilities

Hunter

Boosts Ryuu’s stats against monsters she has fought and gained excelia from before.

This makes her progressively more lethal against familiar foes like Juggernaut.

Abnormal Resistance

Provides resistance to status ailments and abnormal conditions.

Magic Defense

Though not detailed in the text, the name implies increased resistance to magical attacks.

Magecraft

Allows Ryuu to deploy magic circles that enhance magic: higher power, wider range, and better Mind efficiency.

This formalizes her role as a true magic swordsman.

Concurrent Attacks

Increases damage output when she strings together continuous attacks.

This synergizes strongly with her agile, combo‐heavy fighting style.

Magic

Luminous Wind

Attribute: Wind and light

Chant: A long poem invoking distant forest skies, the stars, wandering winds, and the light of the cosmos.

Ryuu creates countless glowing light spheres surrounded by green wind and unleashes them over a wide area, functioning as a powerful area‐of‐effect bombardment.

She also uses the recoil from casting to perform aerial maneuvers and high‐speed mobility tricks.

Noah Heal

Attribute: Healing

Chant: A short verse invoking the faraway song of the forest and the melody of life’s comfort.

Ryuu’s healing magic restores stamina and gradually closes wounds.

It has terrain synergy, growing much stronger when cast in forested areas, but lacks instantaneous potion‐like speed and consumes Mind inefficiently.

Astraea Record

Attribute: Multi‐magic inheritance

Chant: A hymn about fulfilled missions, balanced scales, the fortress of order, the crown of purity, and the revolving justice under Astraea’s name.

This magic is Ryuu’s unique miracle at level 6 and embodies “Justice Inheritance.”

When she begins chanting, glowing hieroglyphic characters manifest within a 5 m radius around her, forming a protective “Stellar Domain” barrier.

This barrier is so tough that level 6 Hegni struggles to break it.

The spell lets Ryuu inherit and use the magic of the ten members of Astraea Familia who fought with her.

These include enchantments like Alise’s flame armor, debuff magic like Ryana’s magic‐power‐lowering flames, healing spells, and more.

The spell requires Astraea’s divine blood as a medium and Ryuu’s emotional bond with her comrades.

If Ryuu ever loses their voices in her heart, the inheritance effect weakens dramatically; the spell’s output is tightly linked to her mental state.

While conceptually similar to Lefiya Viridis’s Elf Ring, which “summons” other elves’ magic, Astraea Record is about permanent inheritance.

In theory, Elf Ring could attempt to call Astraea Record, but without Astraea’s blood and the bonds, the attempt would “whiff,” producing no inherited magic or barrier.

Alvs Lumina

A wooden sword made from a branch of Lymirua’s great sacred tree, passed from Ardi through Shakti to Ryuu.

Forged by the Goibniu Familia, it was extremely durable and enhanced magic, serving as Ryuu’s longtime signature weapon until Juggernaut destroyed it.

Futaba (“Twin Leaves”)

A pair of kodachi classified as outstanding second‐grade weapons.

They once belonged to Kaguya and are kept as her memento; at Kaguya’s request, Ryuu uses them in battle rather than burying them.

Alvs Justitia

A superior “star sword” named “Fairy of Star Justice,” commissioned by Astraea and crafted by Cecil Blackliza for the day Ryuu would return.

It amplifies its wielder’s magic, especially synergizing with elf magic, and incorporates fragments of Alvs Lumina and other rare materials, giving it a raw material value exceeding 1.2 billion valis.

Spirit Raiment

Originally a prototype combat outfit meant for Yufie, this was refitted by Cecil as Ryuu’s exclusive armor.

It emphasizes agility while layering “spirit cloth” to grant high resistance to all magics, particularly elemental spells.

White Silver Longsword (Durandal)

A white longsword with the unbreakable (Durandal) property, delivered by Cassandra as a cryptic gift.

Ryuu uses it to shield against Juggernaut’s devastating attacks during the Loki Familia rescue, though the strain still breaks the bones in her arm beneath the Goliath Scarf.

The Blu‐ray limited bonus for Is It Wrong to Try to Pick Up Girls in a Dungeon? IV Part 2 includes an IF story called “Fairy Branch Story.”

It is a continuation of the earlier web novel Ideal Homeland and represents a parallel world to the GA Bunko mainline.

In this branch, Ryuu becomes Bell’s combat instructor earlier, prior to the Minotaur fight.

She drills him mercilessly, a reflection of the insane training she endured in Astraea Familia—hence the nicknames “rag,” “punching bag,” and other abuse metaphors for Bell.

The deep‐floor arc diverges significantly: Bell and Ryuu hold hands during the “shore of light” scene, Bell confesses mid‐battle, and they declare “Let’s settle this” together against Juggernaut.

They end up forming an official couple, with both the Hostess and Hestia Familia acknowledging their relationship.

Later, a level 5 Bell and Ryuu visit Astraea together to update their status and, at a gentler pace, Ryuu reaches level 6.

On the way back they visit the fairy garden, where Bell reassures Ryuu that he has no regrets, loves her more than anything, and pledges eternal love.

The story ends noting that the future is unwritten: an apocalyptic threat rises, and the two may be separated, but “the hero Ryuu and the Bell who must become a hero will reunite in the branch beyond.”

In this worldline, Bell’s “single‐minded admiration” skill is effectively retired; he has chosen a concrete, mutual love, moving from boyhood idolization to adult affection.

Ryuu’s popularity skyrocketed after volume 14, to the point that she has topped every related character poll across the franchise.

Her “heroine power” is arguably the highest in the series—she consistently gets classic heroine events, from dramatic rescues and shared bath scenes to battlefield confessions and unique IF routes.

The author even admits, in the afterword of volume 14, feeling tempted to “go straight into the fairy heroine’s true ending route.”

Fans often see her as the “third main heroine” alongside Ais and Hestia.

The author and readers also note striking parallels between Ryuu and Ais, such as wind magic, combat focus, trauma history, type of mentor, and even their voice actress’s given name (Saori for Ryuu; Saori for Ais’s voice actress).

Both also serve as Bell’s sparring partners, and there is a running gag of them competing for the title of “Bell’s true master.”

Outside the main series, Ryuu appears in the mobile/PC game Counterside via collaboration as a limited character.

She is classified as a Counter‐type Supporter with buffs particularly effective for Strikers, fittingly synergizing with Bell and Ais’s roles there.

Finally, in the anime’s web previews, Ryuu often performs the title call.

Starting from the second time she does it, she intentionally misreads the episode titles and even repeats incorrect attributions twice in a row, creating a running joke as she deadpan‐delivers increasingly absurd “wrong” titles while the correct subtitles appear on screen.
