2022년 6월 15일 방영
With "true genius" Kei controlling things from the shadows, Group K succeeds in finding Tenji. Facing the "worst thing that could have happened," Tenji makes a phone call to a certain individual. The third game, Friendly Hide-and-Seek, then reaches its conclusion. While the two groups struggled to outwit each other, Shiho, Shibe, and Yutori, who had been temporarily released for the third game, returned to school only to be met with cold stares from their classmates.
