Friend Game

During a class trip, Yuichi and his classmates wake up in an unfamiliar room where a giant doll tells them they must pay off a two million yen debt.

For the first game, the participants answer simple questions by moving a coin together. Yuichi expects things to go smoothly but is quickly surprised.

Yuichi realizes that someone must have been planning to force a loss. He decides to throw a wrench in their plans with a creative if bizarre tactic.

The friends have cleared the game but also confirmed that there's a traitor. Yuichi confronts Shiho when they're alone but she has doubts of her own.
