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.
But how are we going to find him 
when we have no idea where he is?
لكن كيف سنعثر عليه بينما 
لا نملك أيّ فكرة عن مكانه؟
Aber wie willst du ihn finden? Wir haben
keine Ahnung, wo hier unten er steckt.
¿Y cómo vamos a encontrarlo
si no sabemos dónde está?
¿Y cómo vamos a encontrarlo
si no sabemos dónde está?
Et tu comptes faire comment ?
On sait pas où ils se trouvent.
Ma come facciamo a trovarli
se non abbiamo idea di dove siano?
Mas como vamos encontrar ele
 se não temos ideia de onde ele está?
Но как мы будем его искать,
если даже не знаем, где он?
