So I Cant Play H Graphic Novel Volume 01

"One fateful day, Ryousuke Kaga, a typical hopeless romantic and hopelessly perverted high school student, has a chance encounter in the rain with a beautiful girl. After graciously offering both his home for her to dry off in and his help for anything she might need, the mysterious red-eyed beauty thanks him by stabbing Ryousuke in the chest! To further complicate matters, the girl, Lisara Restole, is actually a shinigami - that is, a goddess of death - and Ryousuke has somehow unwittingly agreed to let her use his 'essence' to remain in this world. But instead of shaving years off his life like one might expect of a typical shinigami, Lisara seems more interested in leeching the letch right out of him!"
