A downloadable game

Incarnate Sin Journey 

is an adult RPG Maker MZ open-world game with a focus on the TF theme and other TF-related themes.

---------------------------------------------------------------------------------------------------

Abel, an assassin who makes a living by taking contracts to kill others, one day receives an unexpected assignment to kill the son of an aristocrat living in the Lands of Odellia - a vast island known for its magic and the ancient demonic wars that took place several hundred years ago. He accepts it without much thought; he desperately needs the money. However, while he assumes getting to the Lands of Odellia will be a problem due to his lack of funds and the possible absence of ships capable of sailing there, the opposite turns out to be true - he is warmly invited...


------------------------------------------------------------------------------------------------------

The game focuses primarily on the main story, featuring erotic and sexy scenes with a main theme of TF and more. The TF themes that appear in the game are:

  • Transformation
  • M2F
  • F2M
  • Possession
  • Body swap
  • Corruption
  • Mythical Creature
  • Skinsuit
  • Mental Changes
  • Futa
  • Bimbo/Himbo
  • Anthro

and some secret others transformations.

When I played TF-themed games, I never liked seeing a “Bad End” or anything like that after a TF. That’s why, in ISJ, I tried to avoid it. You play as what you’ve become… you are what you’ve become—depending on the context...of course. In some battles or choices (involving TF), there is unfortunately a Bad End, but this is a significant minority—you can probably guess at which moments; Abel isn’t stupid.

The game is still in development. As of May 5, 2026, a read-only Discord server has been set up where I provide regular updates on the game’s current status and ask for suggestions and ideas from you—the players—so you can also contribute to the game’s creation in a way.
