The first game, "Red Light, Green Light." It explodes the heads of anyone who moves. Fortunately, it cannot move except for turning its head at the teacher's desk. The way to end the game is to press the button on the doll's back.

The second game, "My back is itchy... Meow, meow." It extends its neck with a spring to eat people or harms them with its claws. The game ends when you throw a large bell into the basketball hoop on the Maneki-neko's neck.

The third game, "Kagome Kagome... Who is behind you now?" From the left of the photo, they are Hanako, Taro, Genichi, and Akemi. The participant wears a blindfold while the Kokeshi dolls circle them singing Kagome Kagome. The game ends if you correctly identify even one doll behind you.

In the true final game, "Consideration," everyone can survive except for one person.
