Hajime, Jyugo, Uno, and Nico head to Building 5 to find out about Rock and Yamato.
Jyugo and the others fall into a trap and end up in level 1 underground cell.
There, they find the captured Upa and Liang.
Meanwhile, Hajime is captured by Inori and is escorted to the underground cell where Samon, covered in injuries, is restrained.
Samon reveals who’s behind the incident.
It is no other than Enki Gokuu, the former Building 5 supervisor who became a criminal causing havoc in Nanba Prison in the past. He is also Samon’s brother.
I didn't see it with my own eyes.
.لم أرَ الأمر بأمّ عينيّ
Selbst habe ich es nicht miterlebt,
ich weiß nur, was man sich rumerzählt.
Nunca lo vi.
No lo vimos personalmente.
Enfin, on n’a pas été témoins,
c’est juste la rumeur qui courait…
Non l'ho visto coi miei occhi.
Eu não cheguei a ver 
com meus próprios olhos.
Я не видел этого лично.
