One of Shido's classmates, and his (self-proclaimed?) lover.
A talented girl who is recognized for her high intellect and athleticism (and for her mysterious beauty), she also serves as
part of the Ground Defense Force’s Anti-Spirit Troop (a.k.a. AST).
In the past, her parents were lost to a Spirit attack, and she has sworn revenge within her heart. Her displays of affection towards Shido, opposite to her calm exterior, are quite aggressive.
