Michiko Osada (長田 道子 Osada Michiko) was the younger half-sister of Yuka Osada who she bullied terribly with the other girls in her school's girl's basketball team. She was favored by their parents. The extreme emotional stress Yuka suffered from caused her to fall down the snow covered stairs, killing her and thus being reborn as the Crane Orphnoch. Though she attempted to use her power to help, it backfired when Michiko used her as a scapegoat for her injury and had Yuka kicked out of the family as a result. But when the mistreatment got worse after the school basketball team teased her for the last time, Yuka finally "snapped" and single-handedly slaughtered the entire girl's basketball team, including her half-sister.
