Rock and Yamato suddenly become violent after returning from Building 5 and attack Jyugo and Seitarou.
Covered in bruises, Jyugo tries his best to protect Uno and Nico.
Tsukumo, who has been training in Building 5 with Rock, appears.
Hajime knocks out Yamato and realizes a familiar yellow talisman on the nape of Yamato’s neck.
On the way back from Building 5, 
Yamato-san and Rock seemed oddly quiet.
Yamato-san und Rock waren auf dem
Rückweg von Trakt 5 auffällig still.
Quand on rentrait du 5,
Yamato et lui étaient bien silencieux…
По пути с пятого здания Ямато
и Рок были слишком тихими.
