About the Game

Important

To play this game, you will need a free API key that can be obtained from Google AI Studio.

To keep using the online features—such as the arena and other user-generated content—you will need to pay a separate monthly fee of ¥700, mainly to cover server costs. These features are free for the first two weeks.

A New Experience With Your Original Character

The greatest appeal is seeing AI generate actions and dialogue for your original character, bringing them into the story.

That may be in battle, on an adventure, or even caught up in events you never imagined.

Art and Storytelling

For instance, imagine battling an original character uploaded by another user in the arena.

The AI generates an image depicting both characters fighting and outputs their dialogue and actions as text.

Each time you freely input what your character does, the AI spins a new development that takes your choices into account.

Creative Freedom

Each character has a free-form description field where you can write anything you like.

Thanks to the pioneering creativity of early players, fighting is no longer the only content.

With a bit of ingenuity, you might experience romance, get thrown into a mysterious world, or take a school exam.

You could even have a scenario where you simply play with a dog.

In short, you can have your original character perform various actions within the AI-generated stories.

Experiences Expanded by User Contributions

Every day, new characters, parties, and scenarios are uploaded.

Combined with that freedom, the experiences you encounter are a continuous stream of one-of-a-kind moments.

Once you start playing this game, boredom will no longer be an option.
