Pathetic Demon (Adult\NSFW game)

"Pathetic Demon" is an adult-rated battle fuck RPG set in a university with its own currency and economy, where various services, including sexual ones, can be bought and sold. The story follows a male protagonist who, after being falsely accused of rape, meets a demon who offers him a new identity in exchange for developing the demon's power by having sex with as many girls as possible. Gameplay consists of different types of "fights," such as Lust fights, which use energy instead of HP, with the goal of defeating the female characters through sexual conquest.
