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.
He used to work at the 
Chinese prison we were in.
