Usagi-chan de Cue!!

Matogi Haru is a high school boy who takes care of the animals, especially the rabbits on the rooftop.

One day, a classmate of his, a girl named Inaba Mikami, has a fight with a big strong guy on the rooftop and finds herself falling off the building, still protecting a rabbit.

But instead of getting herself killed, she actually merges with the rabbit!

The new girl, the blonde Mimika, is a combination of Inaba and the rabbit, who is really happy to be with Haru.

But that is something Miku, Haru's childhood friend, cannot accept, since she is actually in love with him...
