Evil Fusion Synthesis

A demon-realm strategist uses forbidden magic to fuse humans and monsters into monster-girl soldiers to reclaim the demon world from human invaders. The game combines tower-offense tower-defense battles with character capture and transformation mechanics—raid human outposts to obtain specimens, convert them into loyal monster-girl troops, and deploy them in combat against human forces and their structures. Captured unique characters and generic enemies each unlock individual sexual scenes after transformation. Between battles, strengthen your monster-girl army, manage squad composition, and progress through an expanding roster of heroines that appear as the story advances.
