Lilith Asami

 is the Trinity Seven of the Luxuria Archive and teacher at the Royal Biblia Academy. During an investigation mission, she discovered the existence of the Demon Lord Candidate Arata Kasuga before introducing him to the world of magic.

Personality
Lilith has a very mature and responsible presence compared to most others, often playing the straight man in many situations. As a teacher, she tends to act strict and formal, believing in working hard to reach one's goals, giving her a bit of a reputation as an Ice Queen. However, in spite of her firm attitude, Lilith is also very kind and compassionate, caring deeply for her student and friends. Often times she tends to watch over others and provides guidance to support them. Feeling a sense of sympathy for Arata Kasuga's plight, she becomes willing to demonstrate her magic for him despite previously stating that magic wasn't something one should show off to others. Furthermore, during a battle, she becomes serious and prioritizes other people's safety over her own. When she was captured by her father, Abyss Trinity, in Sky Library, she was much more concerned with Arata's well being.

Lilith is also rather prudish, disliking actions or words of a sexual nature or implication. Usually, she becomes very embarrassed and uncomfortable whenever anything venereal happens. As a result, her research Thema lies within the Luxuria (Lust) archive and people often delight in teasing her, particularly about her body. However, she can get angry if pushed too much, chastising and even becoming violent depending on the situation. Additionally, because of her serious nature, she is often shocked and sometimes disheartened by many of her peer's nonchalant attitudes, occasionally having to force them to become focused. Nevertheless, Lilith enjoys being with her friends, becoming happy when they are all together. She has a deep trust in them, working with each other as a team effectively.

Notably, others have noted that prior to meeting Arata, Lilith was quite cold towards others but has since become friendlier.

Appearance
Lilith is a young woman with long red hair that reaches down her waist, styled normally with a single strand of her bangs braided, as well as the sides of her hair pulled back and held together with a small basic clip. She is also particularly known for having a very well developed and curvaceous figure. Furthermore, Lilith is rarely never seen without her dark beret, with a few exceptions depending on the situation. Her attire, despite being a teacher, is the school female uniform, almost the same as her students, consisting of a white collared blouse, black jacket, plaid skirt, black thigh-high socks, and penny loafers. However, she wears a necktie instead, and leaves her shirt untucked, with shirttails sticking out below the blazer. When acting as a teacher, she will also wear round glasses as well. Arata has once stated that she is rather stylish.

Magus Mode: In Magus mode, her outfit includes a white, sleeveless collar blouse left untucked, a black tie and elbow length gloves. She also wears a dark short skirt and thigh-high socks, as well as penny loafers. Sometimes, she will also wear her glasses which acts as a targeting system. She also carries a sniper with her along with this mode.

Aeshma: The manifested form of the Luxuria Archive, Lilith's wear simply includes a dark cape with a long collar that barely covers her chest, black elbow-length gloves, and a simple white panty with straps to dark thigh length boots with white cuffs and tips. She can also perform a partial transformation which only summons the cape.

History
Seventeen years ago, in an alternate ruined world, Lilith was sent by Abyss Trinity (Lilith's father) as an infant to the current world as an experiment to see if he could transfer a Magic King element to different dimensions.

As her memories were modified when she crossed between worlds and time, Lilith would not remember her true origins. Nevertheless, Lilith would live and study at an orphanage until she was scouted by Master Biblia due to her magical abilities. Eventually, she would become the youngest person ever to join the Trinity Seven, as well as join the staff of the Royal Biblia Academy as a teacher.

Outer Alchemic
Lillith's Thema's are Abies, Fall and Vanitas from the Luxuria Archive and her branch of magic is '''Outer Alchemic. '''Using the theory of equivalent exchange as her basis, Lilith's magic has the ability to transmute materials into different forms. So far, she has only used this to create weapons such as different types of guns. Additionally, her creations cannot be used by anyone but herself. Because Outer Alchemic requires a significant amount of scientific knowledge, Lilith's high intelligence allows her to master the magic, understanding all of the basic history and fundamental concepts from previous researchers. Furthermore, she has also stated that her magic is one of many different versions of alchemy. Outer Alchemic, in particular, requires her to activate a macro consisting of three stages to activate her spells. These stages, each that can be considered it's own separate magic, are: However, despite the unlimited possibilities of her magic, Outer Alchemic also comes with a few risks. Namely, because alchemy is bound the theory of equivalent exchange, she uses her magic and soul as a cost to process her magic. If she uses too much, she risks turning into a monster. Nevertheless, Lilith has quite a large amount of magic, able to summon a large number of guns mid-air and fire them at will.
 * 1) Comprehension - Understanding the composition of every material
 * 2) Deconstruction - Breaking the material into smaller components. Mastering this with Comprehension creates a small field of destructive magic in a much larger realm.
 * 3) Reconstruction - The final stage which allows her to perform alchemy.

Outside of her magic, Lilith is also quite athletic, being able to wield a large anti-tank rifle with relative ease. She has also demonstrated high proficiency in gunmanship, being a very adept marksman with a variety of guns. Furthermore, Lilith is a skilled tactician, able to develop a counter plan against an opponent's abilities even in the most pressing situations. During her team battle against Levi and Akio, she was able to quickly devise a solution against Levi's Sorcerer Mode using light and crystals to force the ninja out of the shadows.

Notably, Lilith is capable of transferring her magic to Arata through Lilim, which allows him to temporarily become a Paladin.

Due to her lineage from her father, Lilith possesses powerful magical power. As a result, she can easily become immortal and attain eternal youth.

Aeshma
The manifested form of the Luxuria archive, Lilith is the last key that connects this world together with all other worlds. Being a Magic King Candidate and coming from another dimension, she has the power to open holes between dimensions. Doing this allows her to draw out and maximize the power of a Demon Lord or Demon Lord Candidate.

In this form, Lilith becomes capable of materializing floating laser blasters that can eliminate a Demon Lord Knight's attack.

Royal Biblia Academy
Arata Kasuga - Lilith first discovered Arata while investigating a Breakdown Phenomenon site. As a member of Trinity Seven, Lilith was one of his first supporters, introducing him to magic and bringing him to her school, the Royal Biblia Academy. Although Lilith tends to be strict with him as his teacher, she enjoys being with him and interacts with him the most. However, she is sometimes surprised and even frustrated by his nonchalant attitude, often having to be the voice of reason. Even more troubling to her is his perverted behavior, usually becoming very embarrassed, and even angry at times, whenever he teases or does anything mischievous. Despite this, both of them care very deeply for each other's well being, willing to support and fight for one another. Whenever either of them is in danger, they have often worried about the other's safety over their own. Notably, Lilith's personality was originally described more of an "ice queen" prior to Arata's arrival. Over the time she spends together with him, she falls in love with him and becoming jealous whenever he shows interest in other girls. Likewise, Arata finds her very attractive, although whether or not he has romantic feelings for her is uncertain. Nonetheless, the two of them overall have developed a close friendship, even going on a date on one occasion.

Trinity Seven
Arin Kannazuki  - As members of Trinity Seven, Arin and Lilith are good friends, normally getting along with each other. However, Lilith is often times astonished by Arin's lack of common sense, usually having to correct and chide Arin for her behavior and actions. Despite this, Arin does not mind Lilith's strictness, although she does sometimes find it a bit troublesome. During battles, they are able to work together effectively as a team, trusting and caring for one another deeply. In spite of them both being close to Arata, this has not stopped them from remaining friendly with each other. Rarely, do they get jealous of each other and they continue to support one another.

Mira Yamana  - Mira and Lilith are two of the more serious characters amongst their peers, often having to be the voice of reason in many situations. Normally, they get along well with each other, holding respect for one another's abilities and accomplishments. Before Mira joined Grimoire Security, she was mostly shy and distant from others. As a teacher, Lilith would watch over her and try to help despite Mira's resistance. Now, although Mira's position as head of Grimoire security occasionally puts them on opposite sides, rarely do let this cause them to hold a grudge against each other or hinder their friendship. During skirmishes, the two are able to fight and support each other, caring for one another's safety when the other is hurt. Furthermore, though they both may have feelings for Arata, they still remain good friends.

Levi Kazama  - Lilith seems to be excellent friends with Levi. Like Arata, Levi tends to do many perverted things, such as touching and groping Lilith's breasts from time to time. It is shown just like the rest of the Trinity Seven they have romantic feelings for Arata.

Akio Fudo  - It's shown that Lilith and Akio get along with one another, even to the point of going to Akio's job to get food with Arata while on their date, implying a professional relationship of sorts.

Family
Abyss Trinity  - Abyss Trinity is Lilith's biological father who is originating from an alternate world. Upon destroying his own world, Abyss used Lilith as an experiment to see if he could transport a magical element from his world to another. While successful, Lilith would lose her memories of her father and true origins, while Abyss would eventually be summoned by the spriggins in Sky Library. They would not meet again until Lilith and her friends were sent on a mission to Sky Library, where he would abduct her and reveal her true nature. Despite being family, Lilith continues to view him as an enemy, resisting and escaping from him temporarily. While on the other hand, Abyss simply views her as a tool to retrieve his lost power from their original world. Eventually, Arata would save her and together she would help defeat him. This has changed, however. Since being defeated with the aid of Akio's mother's magic, Abyss Trinity's feelings towards his daughter have changed to a more fatherly direction, which embarrasses Lilith.

Hermes Apocrypha (Lilim) - As the master, Lilith normally utilizes Hermes Apocrypha to invoke Outer Alchemich, normally transforming the grimoire into her desired weapon. However, after Lilim becomes sentient, the teacher would eventually accept the child as her daughter despite being initially shocked by the sudden event, forming a close bond regardless of the relatively short duration of their relationship. Unfortunately, Lilim would willingly allow herself to return to her original state in order to protect her parents.
