1. Nanbaka Is a Comedy Anime.

Jyugo makes a routinely escape attempt and is caught by Hajime while he's napping in the Guard's room with Kuu. All the inmates and guards seem to be going through a typical and ordinary day, much to the chagrin of Mitsuru Hitokoe, who wants something exciting to happen during Part 2 of the anime.

2. Super Hitoshi-kun

Hitoshi Sugoroku starts working as a Nanba Prison guard, much to Hajime's surprise. Uno and Rock don't believe that the "kind and cute" Hitoshi is the little brother of the "vicious gorilla" Hajime and try to disprove that they're siblings by testing Hitoshi's abilities as they escape.

3. The Traitorous Building 5

Rock challenges Samon Gokuu to test his strength and is defeated with little effort. The Warden leaves to attend a meeting at the Police Department HQ. Mao Nimaijita accuses Samon about potentially following in his older brother's footsteps. Yamato and Rock return to Building 13 after spending time at Building 5, and while not themselves, they attack Hajime and Jyugo.

4. Something Is Breaking

Jyugo is saved by Tsukumo from an out-of-control Rock. Meanwhile, Hajime deals with Yamato, who's in the same state as Rock. After finding a talisman on the two of them, Hajime and the others recognize the talismans belonging to Building 5. Hajime decides to go investigate the matter, and with much convincing on Uno's part, takes Cell 13 (except Rock) with him. He leaves Building 13 surveillance to Mitsuru Hitokoe. Mitsuru tells Hajime that they contacted Building 5, but nobody has been responding.

5. You Are Weak

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.

7. A Fool

The fight between Liang and Upa against Hachiman continues. Nico shows up out of nowhere and greets Upa, moved by his last line in the previous episode. Qi recalls events from his past when he joined up with Hachiman. Nico intervenes in the fight to save Upa, meanwhile, Uno freaks out about how they all lost sight of Nico. During the fight against Hachiman, Nico's medicine starts to wear off, and an alternate persona appears to take over.

9. Washed Away...

Upa wonders if someone other than Enki is involved in the situation. Meanwhile, Jyugo and his group reach level 2 where they are confronted with numerous Jiang-Shi dolls. As Trois explores the area, they encounter Ruka Gojou and other guards with talisman on their foreheads, Daisen Kokoriki and Daisen Youriki. Trois tries to defeat him with a handmade a flame-thrower he made with leftover parts. Just as they think they are free, Ruka Gojou appears and captures Jyugo.

10. Sound and Words

Jyugo has been captured by Ruka Gojou, but is saved by surprise attack from Trois. Honey gets frustrated with Jyugo's uselessness and wants to leave him behind. Eventually, Ruka, Daisen Youriki and Daisen Kokoriki catch up to the group and Jyugo is caught by Youriki. While trying to help Jyugo, Uno is restrained by Ruka. Though initially reluctant, Honey decides to help. The two inmates of Building 3 decide to repay their debts to Jyugo and Uno, and deal with Ruka and the Daisens. After managing to subdue them, Ruka surprisingly comes out unscathed, now prepared to fight them seriously.

11. Move Forward!

As Ruka begins to fight seriously, Trois and Honey pursuade Uno and Jyugo to go ahead while they continue fighting but Jyugo eventually returns and defeats Ruka with his blades. Kokoriki and Youriki later arrive and try to arrest the escaped inmates. As they escape, Uno, Honey and Trois come up with a plan while Jyugo begins to make his way to Hajime.
