Chihiro Amano

The character line's name is a play on the Japanese word "bosa bosa," which means both dishevelled hair, and to while away the time. The characters are animals who live the way they are. The anime will focus on the everyday life of bunny Sakura, the cat Kathy, and the hamster Ran.

At 14-years-old, Izuna On discovers he and his brother Motoi are both descendents of Tengu (flying goblin-like creatures of Japan folklore). Motoi has wings, which is somewhat rare among Tengu descendants, while On has the ability to communicate with animals. Due to their heritage, the two brothers live together, separated from normal society, and the story focuses on their everyday lives.
