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.
That's why a low-ranking officer 
like me could trick you.
لهذا السّبب استطاع ضابط ذو رتبة 
.متدنّية أن يخدعك
So konnte dich ein niederer Wärter
wie ich aufs Glatteis führen.
Por eso alguien de tan bajo rango
como yo pudo engañarte.
Por eso alguien de tan bajo rango
como yo pudo engañarte.
c’est pourquoi un sous-fifre comme moi
te la fait à l’envers.
Ed è per questo che un ufficiale di basso
rango come me è riuscito a fregarti.
É por isso que um oficial de baixo 
nível como eu conseguiu o enganar.
Вот поэтому какой-то мелкий
офицер обвёл тебя вокруг пальца.
