The premise

Every TSF fan knows the moments by heart: the weight you feel on your chest, a woman's face in the mirror unlike the self you've always known, the first word spoken in a woman's voice.

In this game, you collect those experiences.

An ordinary office worker, and lifelong secret TSF fan, opens an app called TSF Trope Collection. It drops him into one woman's body after another, and every TSF moment he lives through, he keeps — the app calls them tropes.

But the more tropes he collects, the further his own body feminizes. The collection and his transformation are one and the same — and how far he lets it go decides how his story ends.

Possession · collect the classic TSF tropes · gradual self-feminization · an ending that shifts with how far you've turned. Adult content, 18+.

What makes it special

• Possess real women, one life at a time — and live each TSF moment first-hand: the realization, the body, the mirror, the voice
• Collect the tropes — the genre's greatest hits, gathered into one game and yours to keep
• Every trope you collect feminizes you a little more — your collection is your transformation
• Your level of feminization shapes your ending — return to your old life, or keep observing the TSF Trope Collection
• Built to play on both PC and smartphone

What's in the free trial

• Two complete scenarios: Mio Amamiya (24, work-from-home illustrator) and Hitomi Kokubo (29, married housewife), with dozens of tropes to collect

About the game

• This is our first title built on our own original engine (our previous eight games used TyranoScript).
• This game was created by translating a game originally made in Japanese into English.
• AI was used to build the game engine, create the graphics, and translate into English.
• Because production was AI-assisted, you may notice oddities in graphic details or English nuance.
• Depending on save/load timing — for example, saving from the menu screen — the game may not progress correctly. Thank you for your understanding.

The full version is currently in preparation. Become a member to unlock it on release — plus our entire library of 8 full TSF games (with this ninth on the way), all with a single membership.
