After clearing Bad-Mouth Sugoroku, Yuichi and Tenji find themselves trapped in a dark cave for three days. During their isolation, Tenji makes the shocking revelation that he had already experienced a Tomodachi Game in the past. Meanwhile, a team of new opponents lies in wait outside, anxious to challenge the two partners to a grueling third game.
Yuichi! It's too dangerous 
to let an outsider in!
!يويتشي! من الخطير جدًّا أن نُدخل بيننا شخصًا غريبًا
Yūichi, jemand Fremdes ist zu riskant!
Sie könnte uns in den Rücken fallen!
¡Es peligroso aceptar a una extraña!
¡Es peligroso aceptar a una extraña!
Yûichi, c’est trop risqué !
Yuichi! È troppo pericoloso
avere un'estranea nel gruppo!
Yuuichi! É perigoso demais
ter alguém de fora!
Юити,
опасно доверяться посторонним!
