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.
Big oafs like you are so slow. 
It's such a hassle.
.الحمقى من أمثالك بطيئون وهذا مزعج
Wenn solche Muskelprotze nur
nicht immer so träge wären …
Los montones de músculo
son lentos y torpes.
Los musculitos sois lentos y torpes.
Les grands gaillards comme toi
sont trop lents.
Più sono grossi, 
più sono lenti e problematici.
É por isso que idiotas são lerdos
 e não passam de um transtorno.
Великаны всегда медленные.
И это раздражает.
