The origin story of Sirius from Stray Incubus.

Abyss: Ultra Fetish is an adventure set in a dark dungeon,
where the heroes set out to defeat an evil dragon and thus rid the world of her evil.
Along the way, the characters will face many difficulties,
and encounter a variety of enemies,
each of whom will surely set their sights on our luscious girls and want to possess them right in the middle of battle!

Story follows a genius woman and her invented serum side effects.​

The game's protagonist is a huge, muscular barbarian (a parody of classic fantasy, D&D, The Lord of the Rings, and so on). She's already saved the world, and according to the plan, she now needs to find something to do in her free time. I don't want to create a typical game about corruption—the heroine won't get into trouble or hopeless situations, won't lose her powers, won't become a victim of circumstance, but she also won't be an overly domineering, power-hungry individual constantly demonstrating her strength, coolness, and independence. The idea is to create a hentai comedy in the most silly fantasy setting possible, parodying everything imaginable.

Train charming girls in your own gym. Manage workouts, improve stats, plan personalized sessions, and help each heroine navigate her desires and dilemmas. Transform sweat and discipline into confidence, seductive curves, and pure sexuality!
