Overview
Isekai Bastard is a 3D visual novel for players who want dark fantasy harem stories with a corrupt, villainous edge. The tone is crude, mocking, and unapologetically adult.
Story
An isolated outcast with no real-world prospects gets pulled into an MMORPG called Necronomica, a harsh gothic fantasy world populated by monster girls. When he finds a way to bring his in-game power back to reality, he decides to stop being a victim and start being a villain in both worlds, building a following of monster girls as he goes.
Gameplay
Play moves between the real world and Necronomica, mixing story scenes with light adventure and exploration segments as the protagonist grows his influence and his harem. Choices shape which monster girls warm up to him and how far his corruption spreads, with dungeon events and social encounters feeding into ongoing relationship and power progression across both settings.
Features
- Dual-world structure switching between a grounded modern setting and a gothic monster-girl fantasy
- Animated 3DCG scenes throughout
- Monster girl cast with distinct personalities and story arcs
- Corruption-driven progression tied to the protagonist's growing power
Notes
Some heroine content includes sharing (NTS) scenes, and certain character routes split between FUTA and non-FUTA scene variants. Players sensitive to incest or mind-control themes should be aware these appear as part of the game's content.
Installation
1. Extract and run. Mac users, please read the 'readme' txt.
