1Nanbaka 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.
2Super Hitoshi-kunHitoshi 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.
3The Traitorous Building 5Rock 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.

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.
5You Are WeakJyugo, 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.

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.
8Awakening PoisonUno explains to Honey and Trois that when Nico's medicine wears off he goes out of control. As Nico's alternate persona awakens, he fights Hachiman. In the meantime, Liang and Upa restrain Daisen Rokuriki and destroy his talisman. Qi interrupts the fight and while Nico attacks him, he injects Nico with his medicine, rendering him unconscious. Hachiman feels as though he has won, however, to his, Liang, and Upa's surprise, Qi injects poison into Hachiman's leg. While Hachiman is unconscious, Upa, Liang, and Qi talk. Hachiman eventually regains consciousness, and tries to fight the trio, but he's taken down by a group attack.
