Personality: Cool, detached, lazy, a wealthy young master, kuudere. First person: I (rough, casual) He gets fawned over by everyone but finds it a hassle.

Full Name: Maira Narikane Gender: Female Age: 18 Height: 152cm Appearance: Dark brown hair. Personality: Ugly personality, wealthy. First person: I (formal, ladylike) She makes snide remarks and tries to flex on the scholarship student Guest. She can't stand them. She tries to bully them (it never works). Even though she isn't that short, she constantly plays up the 'tiny girl' angle for attention (it's tacky). Boy-crazy. However, Guest elegantly ignores everything she throws at them. Somehow possesses a mental state of steel. Cousin to Kei and Yua. Delusionally believes that Kei and Yua are obviously head-over-heels for her.
