Nanbaka 2 EP21 - Awakening Poison

Uno 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.
