The classic novel of sexual transformation "痴漢達人變女生"(Molester Master: Transformed into a Girl), which has been circulating on the Internet for more than 13 years, has been gamified by the author himself! It is not just a visualization of a novel, but a rich, interactive experience where the story has been completely reimagined and rewritten to fit the game. So if you like erotic games, this title will certainly offer something that hits all the right “spots” —whether you're looking for excitement or pleasure.
◆Story
The protagonist is a Chikan who wants to conquer all the women in the world for his own desires and ambitions, but one day a woman who called herself God appeared and turned the protagonist into a woman, demanding that the protagonist collect 1000ml of sperm within 2 years, or else he would die.
Just when the protagonist thought that turning into a woman and collecting sperm was strange enough, he become entangled in even more extraordinary events. By a twist of fate, he comes across the "Book of Eibon" from the Cthulhu myth, a book that reveals to the protagonist the desired world of "The Northernmost Continent: Hyperborea."
It's up to you if you want to satisfy your curiosity and risk lowering your SAN to explore the legendary Hyperborea, or if you want to focus on being an ordinary man and collect 1000ml of sperm to become a man again.

*The above are just a few characters. This work will introduce many more interesting characters, so come and explore them!
◆Gameplay
The game lasts two years and offers six different itineraries to explore: Research, Convenience Store, Live Streaming, Maid Cafe, Hotel, and Selling Sex. Unlike a traditional simulation game, each of the six itineraries has its own plot and H-events, and the order of execution and decision-making can have multiple effects on the outcome.
In terms of numerical correspondence ending, this game adopts the open-world approach of American RPGs. That is, as much as possible, the player's decisions during the game can be reflected in the endgame, rather than a set of values corresponding to a single game ending.
◆Game Features
◇34 CGs, including 19 exquisite SPINE: H dynamic, other HCG also have to produce simple shadow frame animation or vibration effects, hoping to increase the practicality of this work, the total difference of more than 1,000.

◇The heroine has seven outfits to choose from: daily wear, maid, cheongsam, bikini, fallen angel, dress, and nymphomaniac, some of which are customizable, or simply nude.
◇Sexual Transformation, Cthulhu Mythos (Hyperborea)
◇Immersive TRPG-style experience
◇Nearly all of the HCGs have interactive elements, greatly enhancing the practicality and immersion.
◇Game endings: True Endings x1, Good Endings x2, Usual Endings x1 (Boy Status, Girl Status), Middle Endings x3, Bad Endings x1, and a series of Future Talks reflecting the player's choices during the game.
◆Indie Developer
Hello! I’m FoxSister.
I’m one of the early TRPG promoters in Taiwan and have previously taught at the university level.Because I enjoy adult content, I’m now fully focused on creating adult games.I hope everyone who plays my work can have a fun and enjoyable time.
◆Developer's Note
To make this game the best it could be, I worked with professional Japanese voice actors, and the result completely exceeded my expectations. Take the main character, Beryl, for example—she uses several different identities throughout the story: "Lya" the maid, "Rose" the hostess, "FAngel" the livestream influencer, and more. The voice actress actually created different vocal tones for each of these roles, and even the sounds she makes in the more intimate scenes are distinct. I really hope players will buy the game and enjoy this amazing voice acting.
The voice given to Siena is absolutely mesmerizing—it's so intoxicating, it makes you crave the feeling of holding her close, wanting to keep her in your arms forever.
Of course, the other voice actors did a great job too. Honestly, I think the voice work is on par with what you'd expect from professional anime voice acting, and I'm really happy that an indie game can achieve this kind of quality.
I spent an incredibly long time working on the H-scenes and gameplay because I really love H-games and wanted to make sure all the fun elements were in there. It was a tough process—whether it was designing the gameplay, or working with the CG artists and animators, it took a lot of time and energy.
I didn’t neglect the story either. I know that a shallow, mindless plot isn’t going to cut it, and I wanted players to still remember the game fondly years down the road. So I came up with plenty of interesting stories for players to explore. The game is packed with content, and it takes multiple playthroughs to experience everything. This ensures that the game has great replay value.
The most important thing I’ve noticed is that many H-games often stick to a single ending system, where you can only experience one conclusion (or sometimes, there's only one possible ending to begin with). This makes many of the choices throughout the game feel almost meaningless, because in the end, you're bound to one outcome. I’ve designed my game more like a TRPG, where, in addition to exploring the gameplay, the choices you make will directly influence the epilogue. Your decisions will genuinely shape the story and create lasting changes, making every choice feel significant.
Knowing that you’re all busy, I’ve included a one-click unlock feature after completing the game, giving you access to all the HCGs. Almost every HCG has been designed with replayability in mind, so if you're the type of gentleman who loves to indulge, you'll have plenty to savor.
However, before you rush to unlock everything, I strongly recommend playing through to the true ending at least once. Trust me—it’s worth it. The emotional payoff will hit you in a way you won't expect. I’ve been crafting this story for 13 years, and it’s finally come to life in this game. So please, take your time and truly savor every moment of this experience. You won’t regret it.
*Endless Mode will be unlocked in a new playthrough after clearing the True Ending.
If you’re having trouble reaching the True Ending, there are player guides available on the Steam Guide page.
*For the best experience, we recommend exploring and discovering things on your own during your first few playthroughs.
Based on community feedback, the multi-playthrough experience has now been improved.
