Machi Kuragi is the school treasurer of Kaibara High School. She is a quiet and shy character, and appears to be sensitive and rather isolated.
Machi is the half-sister of Kakeru Manabe. Manabe is very protective of her and can often be seen ordering her around, more out of brotherly love than sibling superiority.
Machi is a very quiet character, though she later begins to show her more stubborn side. She also appears to be quite humble towards Yuki and the other council members, often doing whatever they say and rarely speaking up for her own wishes—that is, if she has any. Despite all such things, however, Machi is a deeply kind and caring girl on the inside, as shown by her heartwarming reactions.
