This game is a short-form, first-person “movement-forbidden” horror title. Players find themselves in a quiet classroom as dusk approaches, alongside a girl with pigtails, participating in a ritual with Kokuton-san.

Trapped in a state where they cannot stand up or move—due to their finger being stuck on a 10-yen coin—they must survive by limited actions: scanning the surroundings, clicking on objects, talking with the girl, and asking questions to Kokuton-san. Their only goal is to finish the ritual before nightfall.

However, strange anomalies have already begun unfolding within the classroom. Staring too long at eerie phenomena causes visual distortions; mental stability deteriorates further as more issues arise.

The game will make its first playable demo appearance at the indie game exhibition “Tokyo Game Dungeon 10,” taking place on November 9 in Hamamatsucho, Tokyo. The event-exclusive mini scenario is designed to let players experience aspects of the game’s atmosphere and controls firsthand.

Game Overview

Kokuton-san no Iu Todori is a short-form, 3D first-person “movement-forbidden” horror game.
The scene: a quiet classroom as dusk draws near. Across from you sits a girl with pigtails who says:
“I’m in trouble… We can’t leave until Kokuton-san goes away.”

Your finger remains glued to a 10-yen coin—you cannot stand or move at all. Your only options are: “look around,” “click on objects in the classroom,” “talk with the girl,” and finally, “ask questions to Kokuton-san.”
The time limit? Sunset. Strange disturbances have already begun inside the room—monstrous entities creep closer as death looms.

Using limited means, you must find a way to finish the ritual and escape safely.
