Ranma 1 2

This is not an artist. Please update your tags. The assorted theme songs are composed by a slew of cutesy J-pop bands. Most notable is Doco, a play on the original band Coco. They’re usually drawn as the main girlie characters of Ranma: Shampoo, Akane, Girlie Ranma, and sometimes the other Tendou sisters.
