Jyugo, Uno, and Nico wind up in an underground cell that happens to be holding Upa and Liang. The two inmates from Building 5 inform the trio that Building 5 has been compromised by the former Nanba supervisor, now inmate, Enki Gokuu. The five inmates escape their cell, thanks to Jyugo, and head off to find Hajime and Samon Gokuu. Along the way they find Honey and Trois locked in a cell.
