He lives as a guest in sweet Akane's house, and he's in love with her, but there's a strange rival, her dog Salomone who plans evil traps to encumber Kappei. But the dog has also another function: he explains all sport rules when a new sport is depicted. Kappei is fond of white female underwear, alwayse tring to lift girl'skirts up.
