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.

But what are we going to do now?

Mas o que vamos fazer
agora? Ainda temos a dívida.
