Kappei is a dramatically short guy, yet he is a master in every sport. He lives as a guest in sweet Akane's house and is in love with her, but there is a strange rival: her dog Salomone (an Italian name), who plans evil traps to encumber Kappei. However, the dog also serves another function: he explains all sport rules when a new sport is depicted. Kappei is fond of white female underwear and is always trying to lift girls' skirts up.
