Biography — The representative for class 2-C has two personalities; the usual polite yet demure honor student, and the churlish Valkyrie that flares up to smack troublemakers into line. This grants Futaba ample respect, despite only peripheral awareness of her condition. She plays violin in the school orchestra. She came from Kofu, Yamanashi Prefecture and now lives in the school dormitory.
