Character:

Mariya is a cross-dressing boy who attends Ame no Kisaki as a girl as a means to win the chairmanship of both the all-male and all-female schools where his late grandmother served as the ex-chairman for both. He deeply respects and loves his grandmother and does not care about actually winning chairmanship. He simply wishes to honor his grandmother's request. He appears to genuinely care about others though this facade is often hidden through some excuse he has crafted for himself.
