Natsuo Ooyama (left) is a big white cat who has no fear of showing how much he enjoys his weight in public... except when Fuyumi's around, that is!

Fuyumi Aikawa (right), who Natsuo has developed a crush on, enjoys spending time with her loved ones. When Natsuo sees Fuyumi, he becomes far too embarrassed to show pride of his blubber, and usually pretends to be unhappy about it so she won't think less of him.
