Eroge no Sekai de Slow Life: Issho ni Isekai Ten'i Shitekita Yarisaa no Daigakusei-tachi ni Tsuihou Sareta node, Henkyou de Muteki ni Natte Shin no Heroine-tachi to Yoroshiku Yarimasu

Iijima Satoru, thirty-two years old and a lifelong virgin, is enjoying a bit of solitary pleasure one evening while the unmistakable buzz of his upstairs neighbor's vibrator drifts down through the ceiling. Without warning, the ceiling gives way—and the woman herself, completely bare from the waist down, comes crashing down directly on top of him. Before he can make sense of what has happened, Satoru finds himself in an entirely different world: the setting of an eroge infamous for its goofy, over-the-top premise. And what a setting it is. In this game, the heroines are perpetually indecent, forever baring their breasts, exposing their lower halves, or strutting about in nothing but thongs—an absolute paradise for a man in Satoru's position. Even better, he arrives armed with a unique power known as the "Ero Note." By writing a person's name in its pages, he can raise their favorability toward him, and the moment that affection maxes out, the skill becomes truly unstoppable—granting Satoru the ability to do whatever he pleases with them. Between a shameless, endlessly lewd world and a game-breaking ability in hand, Satoru's new slow life is off to one unforgettable start.
