Hime-chan no Ribbon Colorful

A girl named Himeko enjoys athletic activities and spending time with boys, yet feels a desire to embody a more delicate and graceful persona, as suggested by her name. After facing discouragement, she receives a magical hair ribbon from someone she knows, which allows her to resemble any person in the human world. In exchange, she must serve as a subject for observation in a magical study. The story is a reimagining of a 1990s shoujo manga and anime created by Mizusawa Megumi.
