Mahou Shoujo Isuka

Based on an erotic game, "Mahou Shoujo Isuka" centers on a magical girl who unwillingly houses an evil stone. This stone contains a portion of the king of hell's power, placed within her to prevent his revival in another world. Now, clans from the hellish realm relentlessly pursue her, seeking to reclaim the stone. However, simply destroying her body won't suffice. Instead, these demonic entities employ various methods to disgrace and corrupt the magical girl, making her life a constant struggle against their depraved advances. The anime explores themes of corruption, power, and the battle against evil.
