Change 123 is a high-energy martial arts action manga centered on Motoko Tani, a shy and gentle girl suffering from extreme dissociative identity disorder caused by intense childhood training. When threatened, her personality switches into one of three hyper-lethal combat personas — each specializing in different martial arts and battle instincts. Balancing school life, comedy and brutal close-quarters combat, the story blends psychological themes with exaggerated action as Motoko struggles to live a normal life while her alternate selves dominate the battlefield. Known for its fast pacing, over-the-top fights, split-personality gimmick and mix of humor and violence, Change 123 attracts readers searching for martial arts manga, multiple personality protagonists, action comedy, school battle stories and unconventional fighting heroines. Often compared to History’s Strongest Disciple Kenichi, Tenjou Tenge, Freezing and Girls of the Wild’s, it stands out as a chaotic blend of ecchi humor and intense hand-to-hand combat.
