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.
At a time like this, we have 
to use any means necessary.
.علينا استعمال أيّ وسائل ممكنة في وقت كهذا
Das ist der falsche Zeitpunkt,
wählerisch zu sein!
No podemos darnos el lujo
de ser quisquillosos.
No podemos permitirnos 
el lujo de ser quisquillosos.
Tous les moyens sont bons
dans ces moments-là.
In questi momenti dobbiamo
usare qualsiasi mezzo.
Em tempos assim, precisamos
 usar os meios necessários.
В такие времена все средства
хороши, как говорится.
