Can't Take It Off? Episode 4

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. The suit contains a clothes changing demon that feeds off the life of the wearer. The suit changes all the female students' clothes into cliché cosplay clothes and tries to kill off Chizuru but she and Kouta combine, freeing Chizuru of the evil suit and destroying it once and for all.
