Civil, who thrills in the sensation of being the "enemy of the world," explores Polka's connection to the mortal world. Meanwhile, Takumi confronts Polka with his tumultuous emotions.

Inspector Iwanome makes a bold gambit, offering to embody the Fire-Breathing Bug's desire for revenge and vowing to dismantle the Sabaramond network in Japan. His offer is a gamble—an attempt to preserve innocence while satiating the Bug's thirst for retribution.
