Issei, Rias and the rest of the gang continue to have a variety of misadventures with plenty of bountiful breasts to be exposed along the way. Whether they're transporting to an uninhabited island to sunbathe in revealing outfits, accidentally turning Koneko into a pervert with personality-changing tea, or getting a chest workout while making udon dough from scratch, these high school demons have plenty of fun with their friends.
Self-proclaimed, proud pervert Ryousuke loves women – to him, their butts and breasts are a 'treasure box' of joy for all men. So when the boy spots a fiery-haired girl standing in the rain one day, he invites her to his house – but he didn't expect to be stabbed with a magical sword in return! The girl, Lisara, is actually a high-level shinigami who must absorb the spiritual powers of others to survive in the human world. Until she can find a genius with enormous expendable energy, she's decided to form a contract with Ryousuke, but unfortunately for the busty babe, the horny teen's mojo is fueled only through his constant perversion. While looking for Lisara's true prize, the two must deal with other well-endowed shinigami and other foes alike, all while trying to maintain a 'typical' school life together.
