Mature Content Description

The developers describe the content like this:

Like my other games, this game has sex scenes when the player hits a failure condition. some enemies also strip the player character.
The game also has villains that deal in mind control and cultish behaviour.
Depictions of BDSM, restraint, spanking, cumflation, sexual assault, sex slavery, sex with bipedal monsters (minotaur), drug use, and non consensual sex.
All of which are done in a lighthearted manner for kink/fetish value. but some people still might find them upsetting.

About This Game

Phantom Thief Sylphy is a stealth adventure game. Sneak, evade capture and solve puzzles as you steal from and expose the corruption of the rich and powerful. Try not to get caught though, lest you become another victim.

This game is a spin off/prequel for Abyssal Agent Alyss and includes Sylphy's first brush with the supernatural. She and her hacker partner: Voyeur work together to solve a missing person case. Unlike Abyssal Agent Alyss, this game is not an rpg.


Run around, avoid detection, swing to new heights with Sylphy's Grapple Gun. If She has nothing to defend herself her clothes will be torn off and she'll be captured. but after the lewd scene she'll escape and continue unless something more permanent occurs.

Features -

Live2d sex animations

Casual difficulty, only certain fail states result in a game over. but you can also savescum if you encounter difficulties.

Unlockable gallery upon completion.

Phantom Thief Sylphy is made with RPGMaker MV.
