Lilith Asami

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.
