Lilith has a striking figure with a very voluptuous bust and an overall excellent style that is frequently commented on by other characters.

She has long red hair, styled with a single braid on the right side, and often wears a beret that emphasizes her intellectual look.

Her beauty and proportions are described as “unreasonable” or “too much” by Arata Kasuga, who is endlessly flustered by her chest.

Despite her revealing curves, she is personally rather innocent about such matters, which makes her easy to tease.

She typically dresses in outfits that mix a scholarly, teacher-like look with a combat-ready style suitable for a mage.

Her underwear is often noted to be striped panties, a recurring comedic element in the story.

Lilith is fundamentally serious, responsible, and level-headed, often acting as the “straight man” and voice of common sense among the cast.

As a teacher at a young age, she takes her duties and rules seriously and tries to maintain a strict and professional demeanor.

In daily life she speaks politely and uses formal, respectful language with others, reinforcing her strict-teacher image.

However, when it comes to Arata Kasuga, her composure easily crumbles, especially when situations turn lewd or embarrassing.

She is easily flustered by sexual jokes, skinship, and teasing about her body or romantic feelings.

Because of this, she often ends up not only as the one correcting others but also as a frequent target for teasing and light-hearted harassment.

Underneath her strict exterior, Lilith is kind, caring, and capable of quiet warmth.

Her reactions, embarrassment, and hidden tenderness make her one of the more emotionally expressive and relatable members of Trinity Seven.

Magical Discipline and Archive

Lilith is one of the Trinity Seven and a mage of exceptional caliber.

Her specialized magic discipline is Alchemy (Outer Alchemic).

Her Magic Archive is Lust (Luxuria), and within this archive her main themes are:

Life (Abies)

Erasure (Fall)

Void (Vanitas)

She possesses the grimoire Hermes Apocrypha, a powerful magic book that serves as the core of her techniques and transformations.

This combination of archive, themes, and grimoire allows her to manipulate existence at a deep, conceptual level.

Lilith has vast theoretical knowledge, the ability to create almost any “substance,” and the magical power to maintain those creations stably.

Because of this, she is regarded as a “genius” even among powerful mages.

Combat Style

In battle, Lilith uses alchemy to transform her grimoire into a variety of weapons and tools.

Her primary combat style centers on ranged combat using magically generated firearms.

Her main incantation is “Realize” (Recognition Manifestation), used to manifest her grimoire into over twenty different types of guns.

Beyond guns, she can also reshape the grimoire into many other forms, adapting to the needs of each situation.

At first, Lilith often serves as long-range support, providing covering fire and tactical backup for her allies.

As the story progresses, especially after the Divine Song Gate arc, she increasingly takes on a more offensive role.

After mastering her Demon Lord factor as the Demon Lord’s Daughter, she gains access to heavily destructive magic.

She becomes capable of fighting alone and completely annihilating her enemies, shifting from support to a direct, overwhelming attacker.

Secret Techniques and Demon Lord Factor

Lilith’s signature secret technique is Infinite Absolute Barrier (Aeshma Deva).

In advanced developments, this ties into her role as a weaponized embodiment of a Demon Lord-related armament.

Her Demon Lord factor was revealed during the investigation in the Sky Library.

When she is struck by attacks from a controlled Lugh, it becomes clear that she, like Arata Kasuga and Hijiri Kasuga, carries a Demon Lord factor.

Shortly after, Abyss Trinity appears and addresses her as “My daughter, Lilith Azazel,” before taking her captive.

Under Abyss Trinity’s hand, she is manifested as the “Last Key” in the form of “Aeshama”, a powerful Demon Lord weapon-form.

She is ultimately freed from this enforced manifestation through Arata’s “Domination Field”, which breaks Abyss’s hold on her.

From episode 54 onward, Lilith gains the ability to don or embody “Aeshama” by her own will, turning that power from a curse into a chosen weapon.

Through training and confrontation with her heritage, Lilith eventually fully acquires Void (Vanitas) as a theme.

By connecting, through Kaina, to her already-destroyed home world, she completes her understanding of emptiness and nothingness and adds that to her arsenal.

Arata Kasuga

Lilith clearly develops romantic feelings for Arata Kasuga, though she rarely admits them outright.

While the series never has her openly state “I love you,” her behavior and reactions make her affection unmistakable.

When she once misunderstands a situation and thinks Arata is about to kiss her, she blushes heavily but still prepares herself to accept it.

After the Sky Library incident and her rescue from Abyss Trinity, she finds herself unconsciously staring at Arata and being drawn to him.

Other members of Trinity Seven regularly tease her about her feelings, often combining this with remarks about her impressive figure.

These situations frequently leave her flustered, shouting, and unable to maintain her usual strict composure.

Despite the embarrassment, Lilith is deeply supportive of Arata’s goals and growth.

She stands by him in major battles and emotional turning points, balancing between teacher, comrade, and potential love interest.

Abyss Trinity and Family

Lilith’s true origin is one of the most unusual and significant in the series.

She is the daughter of Abyss Trinity, a Demon Lord who awakened in another timeline, and Arul Asami, a fallen angel who once served as a Judge and became his partner.

Both of her parents are beings who have perfected the magic of Lust, to the point that the concept of “lust” no longer exists for them at a normal level.

Despite this conceptual absence of lust, a daughter—Lilith—was born between them, making her existence uniquely special.

Because of this metaphysical peculiarity, Lilith is said to be the key to defeating the absolute god known as the “Goddess of Deep Darkness,” who will eventually revive.

Her existence stands outside normal cycles and concepts, making her a pivotal element in the fate of the world.

When Abyss Trinity becomes both a Demon Lord weapon and a doting father, Lilith has trouble figuring out how to interact with him.

She is somewhat awkward and distant at first, but she does recognize him as her real father.

Over time, she shows him small kindnesses and allows a fragile but genuine connection to grow.

During a flashback set before the Divine Song Gate arc, she seeks Abyss’s help to gain greater power for the coming battle against a Great Demon Lord.

Through Abyss and the medium Kaina, she connects to her destroyed home world and fully masters the theme of Void.

Later, when the battle against the Goddess approaches, Abyss reveals to her the truth of her birth and her parents’ past.

At that moment, Lilith receives a gift from her mother: the grimoire “Apocalypse of Expiation” (Expiation Apocalypse).

Overwhelmed, she sheds tears as she accepts this legacy, feeling both the weight and love of her heritage.

Trinity Seven and Others

As one of the Trinity Seven, Lilith is a core member of the main magical elite group in the series.

She works closely with other members such as Lieselotte Sherlock, Levi Kazama, Mira Yamana, Yui Kurata, Arin Kannazuki, and Akio Fudou.

Among them, Lilith is often seen as the “responsible older sister” or teacher figure.

However, the others frequently turn her into the butt of jokes, especially regarding her body and her feelings for Arata.

She has professional and academic ties to figures like Master Akasha, Master Liber, and the Headmaster of the academy.

Through her investigations and battles, she also encounters beings like Lilim, Lugh, Last Trinity, Ilia, Selina Sherlock, Anastasia-L, and others drawn into the orbit of Arata’s journey.

Lilith is one of the first Trinity Seven members introduced and serves as a gateway character into the world’s magic systems.

She teaches Arata at Royal Biblia Academy, explaining grimoires, archives, and disciplines while also pulling him into high-stakes conflicts.

In early arcs, she functions as an instructor, tactical supporter, and commentator, helping the audience understand complex magical concepts.

She engages in combat mainly through ranged support, using her alchemical firearms and analytical skills.

As the story advances, Lilith moves from a supporting role to a central heroic figure.

The revelation of her Demon Lord factor, her kidnapping by Abyss Trinity, and her transformation into Aeshama raise her narrative importance dramatically.

Her identity as the Demon Lord’s Daughter and the daughter of Abyss Trinity and Arul Asami makes her key to the overarching threat of the Goddess of Deep Darkness.

She becomes both a literal weapon and a symbolic hope against absolute godhood and annihilation.

The Sky Library incident marks a turning point where she shifts from being primarily Arata’s teacher to also being his equal in destiny.

With the ability to willingly don Aeshama, mastery over Void, and the inheritance of Expiation Apocalypse, she stands on the front line of the final conflicts.

Lilith is fundamentally an existence outside the ordinary cycle of life and death.

As a being from another world whose origin lies in a broken timeline and conceptual anomalies, she is not bound by normal reincarnation.

Her body stops aging once she reaches a certain physical age, effectively freezing her in youthful form.

Because of this, she is destined to live for an eternity, carrying her power and responsibilities across endless time.

This immortality underscores her role in resisting gods and absolute beings, while also posing emotional dilemmas about love, loss, and time.

She must navigate her eternal existence while tied to mortals like Arata and to transcendent entities like her parents and the Goddess of Deep Darkness.

Despite being only 17, Lilith serves as a teacher at Royal Biblia Academy.

This position reflects both her exceptional talent and the academy’s acknowledgment of her genius-level understanding of magic.

She educates students in magical theory and practice, especially in the field of alchemy and grimoire usage.

Her lectures and guidance are highly competent and thorough, even if her class sometimes devolves into chaos thanks to Arata.

Her dual role as both a student-age girl and a professional teacher creates many comedic and dramatic scenarios.

She strives to maintain authority, but her flustered reactions and personal entanglements often undermine that strict image in charming ways.
