In an attempt to win Kouta and defeat her enemy Nozomu, Chizuru breaks into a forbidden supply room and steals a cursed bunny girl suit. Her problems start when she cannot take off the suit and is forced to go to school in it with everyone staring at Chizuru and calling her names behind her back. It is later revealed that the suit contains the soul of a spider demon that feeds off the life of the wearer. The suit then changes all the female students' clothes into cliché cosplay outfits and tries to kill off Chizuru but she and Kouta combine, freeing Chizuru of the evil suit and destroying it once and for all.
