Developer Notes


This game contains explicit depictions of consensual sex and uncensored genitals. All characters depicted are 21 years old or older.

The story takes place in a female-only fantasy world, in which all women possess the intrinsic magical ability to become temporarily “futanari,” i.e., grow male genitals (note: it is possible to finish this game without playing any futanari scenes).

The adult scenes in this game are either female x female (~70%) or futanari x female (~30%).
