Mira Yamana

Personality
Mira is a serious and driven individual, having a very passionate belief in justice. Dedicated to her role as the head of Grimoire Security, she can be quite cold and ruthless sometimes. In order to stop or prevent a Breakdown Phenomenon, she will not hesitate to take a life in order to complete her mission. Because of her strong sense of responsibility, she normally has a no-nonsense attitude, appearing unfriendly and strict most of the time. Furthermore, Mira greatly dislikes anything or anyone she considers impure, becoming agitated or even greatly embarrassed in some situations. However, she has shown some concern about her role as Grimoire Security, feeling conflicted about the dark nature of her job. Despite this, she remains determined to fight against impure existences. Mira has also been shown to be a very capable leader and fighter, usually remaining calm and collected during dangerous conditions. This allows her to act and think intelligently, planning her moves ahead to avoid trouble.

However, underneath her stern exterior, Mira can be a very kind and caring girl. Notably, before becoming the head of Grimoire Security, she was initially someone who could not express and assert herself, being very shy and distant with everyone. As a result, she became very isolated from the school until she met Akio who inspired her to change. While she rarely shows this side of her anymore, since meeting with Arata, she has become more mellow and honest with others. Additionally, Mira is quite pure, becoming very unnerved when anything perverted happens, sometimes even reacting violently. As such, this has been exploited as a weakness many times. However, since interacting with Arata, Mira has become more accustomed to perverse situations. Particularly, when she loses her clothes, she reverts back to her original personality, becoming very meek. Although Mira is often considered a genius, she herself has never thought of herself as one. However, she nevertheless has pride in her magic and strength. Overall, Mira cares deeply for her friends, willing to fight and protect them. Although she is usually surprised or distressed by many of their antics, she continues to enjoy their friendship.
