Ryosuke Kaga is an ecchi high school boy attending Momozomo Academy. One day, he meets a girl standing alone in the rain. She is
Lisara Restor, an elite Grim Reaper, who visited the human world in order to find The Singular Man. Ryosuke makes a contract with Lisara and she sucks energy required for her activity in the human world from Ryosuke. The source of the energy is his perverted spirit. To recover the sexual desire, Ryosuke has no choice but to help Lisara’s search.
NEVER make a deal with a wet goddess you’ve only just met. That’s a lesson Ryosuke Kaga learns the hard way when he foolishly agrees to let Lisara Restole use some of his “essence” to stay in this world. Because despite her smoking hot appearance, Lisara’s actually a Shinigami, a Goddess of Death. However, she DOESN’T steal years off his life like any decent Shinigami would do. Oh no, instead she sucks him dry of something much more perverse by leeching off his lecherous spirit and draining his ability to enjoy… er… the things that teenage boys normally spend most of their time thinking about! And now that he’s been de-debased and de-debauched by her un-dirty trick, the poor regenerated degenerate’s only hope of getting his licentiousness renewed is to join the queen of mental-clean on her quest, since when she leaves our mortal plane he regains his normal immorality! But the termination of the probation of his reprobation isn’t guaranteed, because Goddesses of Death can be really harsh mistresses and it’s going to be anything but easy to go back to being sleazy!
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.
