Plot
Masaharu Tsuwabuki is a normal unsocial student until one day he meets a new student named Sumomo Akihime, and another girl named Nadeshiko Yaeno, Sumomo's close friend. That same afternoon, he suddenly bumps into Arthur, a servant of Nona Yūki from Figurare who at the time was disguised with a mask. The collision causes Arthur to drop a bag full of magical potions; amid gathering up the scattered cans, one of them is accidentally switched with Masaharu's soda can. Upon drinking it, he transforms into a stuffed animal lamb at night. He must collect seven stardrops, in order to return to normal.
