Change 123 (ちぇんじ123, Chenji Hi-Fu-Mi) is a manga series written by Iku Sakaguchi and illustrated by Shiuri Iwasawa. This action-comedy follows Motoko Gettou, a normal female high school student, with a not so normal secret. When she was a child she was trained by her three martial artist fathers. Subjected to excessive physical and mental training, Motoko developed three distinct split-personalities known as Hibiki, Fujiko, and Mikiri. Collectively they refer to themselves as HiFuMi. Each individually skilled gained a mastery in combat skills learned from each of her fathers. As Motoko tries to live a normal high-school life she only seems to find herself in the most awkward situations, courtesy of HiFuMi.
