Sex Change Contract and Molester Girl is an adult role-playing game built in Unity by FoxSister, featuring 2D animated artwork. Players take the role of a man infamous for groping women, who is suddenly transformed into a woman by a self-proclaimed goddess. Stripped of his anatomy, he must gather 1000ml of semen to revert to his original form. The game incorporates RPG mechanics, multiple endings, monster girl encounters, and a protagonist whose gender shifts during the story.
The current build is version 1.4.3, released on January 7, 2026, with development still in progress. It is available on Windows in English, Chinese, and Japanese, and ships without content censorship. The latest patch improved performance during arena battles, building on the prior update that introduced an auto-play mode and new visual effects tied to specific endings. Earlier fixes addressed CG playback problems on the Kyabakura route and corrected interface bugs that could cause unintended status effects.
Developer's description
Why did I become a girl? I am the Chikan who has brought many women to orgasm, and today I will be brought to orgasm instead. The woman who calls herself a god wants me to collect 1000ml of sperm to become a man. Damn! I want to fuck her, but where is my dick? Ahhhh! My proudest penis is gone!

v1.4.2
In this update, in addition to adding an Auto-Play feature, we’ve also added some “interesting” visual effects.
We recommend that players who have a save file for the Idol Ending load that save and take a look. If you don’t have one, just load any save that’s about to enter an ending and give it a try!
(These effects have also been added in other places—feel free to explore and discover them.)

1.Bug Fix: Fixed an issue where the Convenience Store Manager [Resistance] option could not be correctly determined.

v1.3.2
When the full version of the game was first released, there was no special ending designed for a virgin clear.
However, after seeing how many players enthusiastically challenged themselves to finish the game as a virgin, I decided to add a hidden ending for it.
Since a hidden ending without any CG would be too dull, I asked the illustrator to create a special hidden CG.
You can view the full image by clearing the game as a virgin.
(The preview shown on this page is only a partial image. This hidden CG cannot be viewed in the Scene Replay; it can only be seen through the hidden virgin ending.)
Players who have already cleared the game as a virgin don’t need to replay from the beginning — simply load a save before the ending, and the hidden CG will appear.
Note:
For those who want to try a virgin clear, you don’t need to aim for the True Ending.
As long as your character remains a virgin, you can unlock this hidden CG.
v1.2
Endless Mode
When Endless Mode is enabled, you will not be forced into the ending at week 97—you can continue playing indefinitely. If you wish to enter the ending, an option will appear in the schedule menu.
Endless Mode unlocks after clearing the True Ending. For those who haven’t reached it yet, I recommend trying to clear it yourself. But if you find it too difficult, there are guides and strategies shared by players in the Steam Discussions and Guides.
Bug Fixes
Fixed freeze during the Ferris wheel date with the boyfriend.
Fixed freeze in the Deep Ones’ community theft event.
Fixed rare freeze issue when changing outfits.
Animation Improvements

The idea of the game is fairly appealing, a DnD-esque approach to gameplay where actions like avoiding harassment necessitates some sort of stat check through a dice roll, and also the idea of juggling stats where you have to make…
