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.
I'm not gonna let something 
like that happen again.
.لن أسمح لشيء كهذا أن يحدث ثانية
Ich werde nicht noch einmal zulassen,
dass so etwas passiert!
No dejaré que vuelva
suceder lo de aquella vez.
No permitiré que ocurra de nuevo.
Je ne veux plus jamais avoir
à revivre ça.
Non permetterò che succeda
di nuovo una cosa del genere.
Não vou deixar algo daquele
 tipo acontecer de novo.
Я больше не допущу,
чтобы подобное повторилось.
