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.
All we need to do is make sure 
we don't get out by ourselves.
كلّ ما نحتاج لفعله هو الحرص 
.على عدم الخروج بأنفسنا
Wir dürfen bloß nicht allein abhauen.
Es tan sencillo como salir escoltados.
Es tan sencillo como salir escoltados.
Il suffit qu’on sorte accompagnés.
Dobbiamo solo assicurarci
di non uscire da soli.
Tudo o que precisamos fazer
 é não sairmos sozinhos.
Нам просто не надо выходить самим.
