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.
And we ended up being locked 
up in this underground cell.
.وانتهى بنا الأمر مسجونين في هذه الزّنزانة التّحأرضيّة
Und wir werden gegenwärtig in diesem
Untergrundkerer festgehalten.
Y acabamos encerrados en este calabozo.
Y acabamos encerrados en este calabozo.
À présent, on se retrouve
enfermés dans ce cachot.
E siamo stati rinchiusi
in questa cella sotterranea.
E acabamos sendo presos
 nesta cela subterrânea.
А потом мы оказались заперты
в этой подземной камере.
