Watch NANBAKA

Seitarou Tanabata is all fired up for his first teaching job at a high school But Nanba Building 13 High School l is filled with delinquents. The students are troublemakers and even the teachers are odd. Seitarou is already bullied by 4 students in the 3rd year, class 13 on his first day. Then, the number 1 troublemaker, Hajime Sugoroku, returns after serving his suspencion. Can Seitarou ever become the teacher he always wanted to be?

Jyugo heads towards Hajime's cell on his own, while the others search for a different guard.

Jyugo, Uno, Nico, and Trois are attacked by Ruka's powerful weapon, Bashosen. Honey tries to fight him off, but at this rate, all four will perish. Trois tells Jyugo and Uno to go ahead of them while they fight Ruka.

Jyugo and the others continue to run from Ruka's attack, but Honey tells Jyugo not to follow them because he believes Jyugo's only in their way. Jyugo starts to open up about himself to Uno. However, Ruka is quickly approaching.

Beating Hachiman, Nico, Liang, and Upa move ahead guided by Qi. Upa feels someone other than Enki is involved in the incident. Meanwhile, Jyugo, Uno, Honey, and Trois encounter Ruka, a former Building 5 guard who has escaped from his cell.

The medication completely gone from his system, Nico suffers and goes berserk. Wanting his medicine, he attacks Hachiman.

The escaped convict, Hachiman, appears in front of Liang and Upa. Meanwhile, Uno and Jyugo are concerned about Nico, who doesn't have his medication. It seems something horrible will happen to him if he doesn't take his medicine.

Jyugo, Uno, Nico, Liang, Upa, Honey, and Trois make their way through Building 5's underground cell to find the captured guards. They hide in the file room where Jyugo finds some shocking information about himself!

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 the level 1 underground cell. There, they find the captured Upa and Liang.

Rock and Yamato suddenly become violent after returning from Building 5 and attack Jyugo and Seitarou. Covered in bruises, Jyugo tries his best to protect Uno and Nico.

Yamato takes Rock and Tsukumo to Building 5 for training. Rock challenges Samon to a duel, but he is defeated by only one finger.

A new guard has come to Building 13, and not everyone is happy about it.

Jyugo escapes from prison again and Hajime Sugoroku goes looking for him, but it's a usual day for the inmates and guards. Many things have happened, but it seems like nothing has changed in Nanba Prison.
