Kouta is the prize in a battle fought with food between Chizuru and Nozomu.

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.

Nozomu's brother, Saku Ezomori, puts a special bracelet on Kouta's wrist that will hurt him if he becomes sexually aroused, and Chizuru worries that if she tries her normal flirting behavior she could eventually kill him.
