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.

What prison guard wouldn't 
apprehend escaped convicts?!

Какой охранник не станет ловить
сбежавших заключённых?!
