About this game
Note: This game uses generative AI, so playing it consumes in-game points. Points are a paid item.
You receive 50,000 points as a first-time bonus, which is enough for roughly 15 battles.
(For reference: text generation costs around 1,500 pt per match, and image generation around 600 pt per image. Image generation can be turned off.)
(A detailed price list is at the bottom of this page.)

A novel-style game that could only have been born now
Eternal Hand delivers a completely new experience by combining text-generation AI with image-generation AI. On the battle screen the story is written out as though it were a novel, with illustrations generated to match each scene.
There are no preset choices like those in a typical visual novel. You simply type whatever you want to say or do, and the story unfolds freely from there.

Over 1,000 recruitable monsters! The RPG Mode players call a rabbit hole
RPG Mode is a solo-only mode built as the entry point to the game.
The core loop is straightforward: answer a personality quiz to create yourself, form a party, take monster subjugation requests from the request board, and earn experience and rewards. What sets it apart is that every subjugation target can be recruited as a companion - and there are more than 1,000 of them!
Every monster was designed to be one of a kind, with no duplicates. Build the party that suits your taste from among them.



Create characters with no limits and battle parties from all over
One of the biggest draws of Eternal Hand is the Arena. Restrictions have been stripped away as far as possible, so you can create characters with any appearance and any background you like, upload them as a party, and battle the parties other players have uploaded.
Thanks to an active community, just under 2,000 parties have been uploaded so far.


A Scenario Mode deep enough to build a short RPG in
Scenario Mode comes with long-term memory, so you can form any party you like and play through a wide range of scenarios. Best of all, you can create scenarios yourself and share them. Simple ones are easy to make, and for anyone who wants to go further, scenes, images and flags give you more than enough to build something on the scale of a short RPG. There is also automatic scenario generation, so you can jump straight into the kind of story you feel like playing.
