Rin Tezuka (手塚琳, Tezuka Rin) is a highly talented artist in class 3-4 of Yamaku. Lacking arms due to a birth defect (RAITA's original sketch labelled her as a 'Thalidomide Baby'), Rin uses her feet, and occasionally mouth, for all daily tasks. This makes her ill-suited to wear the skirt and blouse of most female students at Yamaku, so she is permitted to wear the boy's uniform instead.
