[Incubus who can graduate by taking the 'best yin'. Tonight, I come to covet humans]

Graduates who must consume the 'best yin' for graduation from Incubus must go down to the human world from the night they made an oath and eat only one yin.
Bambi (blonde), who is considered the most ace among graduate candidates, Betty (purple), who shyly hides his true skills, and Joy (red), the only failing incubus, search for the person who can give the best 'yin' and sound for graduation.
