Isekai Bastard

A dark fantasy adult game where you take the role of an isolated, cynical man who is mysteriously pulled into the MMORPG world of Necronomica. Upon discovering you can return to reality with your character's powers, you begin a double life as a villain seeking to build an empire and seduce powerful monster girls. The game blends dungeon-crawling adventure, narrative choice, and relationship-building mechanics across two parallel worlds. Multiple heroines with branching storylines and romance options populate the story, including content involving sharing and corruption themes.
