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 never would've thought there was a 
huge garden like this right above us.
لا أصدّق أنّ هنالك حديقة ضخمة 
.كهذه فوقنا مباشرة
Y pensar que había un jardín
como este sobre nuestras cabezas.
Y pensar que había un jardín
como este sobre nuestras cabezas.
Chi avrebbe potuto pensare che ci fosse un giardino
così grande proprio sopra le nostre teste?
E pensar que tinha um jardim
 deste tipo acima de nós.
Я бы никогда не подумал, что прямо
над нами расположен такой огромный сад.
