The episode begins with Solitaire receiving a call from Grocer, an undercover informant. They discuss a series of sensitive pieces of information, including police communications that reveal ongoing conversations between Inspector Tsubaki Iwanome and the allegedly missing former Inspector Hosorogi. This exchange uncovers a corruption network involving Chief Commissioner Habaki and hints at his entanglement with a shadowy figure named Sabaramond.

The narrative then shifts to a flashback, where Xiaoyu recalls a violent encounter with Majiri Agakura, a member of the mysterious Agakura family. Majiri offers Xiaoyu a place in their family—an offer tied to a failed operation in the past, during which Xiaoyu was also marked as a target by the Agakuras.

Back in the present, the Shinoyamas, a family with close ties to Xiaoyu, are portrayed as a protective and devoted clan, to whom Xiaoyu reaffirms his loyalty to the Heilei Clan—or rather, the Agakuras. This declaration of loyalty highlights the Shinoyamas' influence and the intricate web of allegiances in the underworld.

The episode takes a mysterious turn with the appearance of the Fire-Breathing Bug, an enigmatic creature capable of inexplicable acts. Arase attempts to contain the chaos caused by the insect, leading to a broader discussion about the nature of this being, which suggests a blend of advanced technology and arcane forces.

Later in the episode, the Agakura siblings, Majiri and Momoya, tend to Misaki, a freshly transformed "vampire larva" under Polka's influence. The Agakuras recognize Misaki's potential and offer her a place in their family.

At the climax of the episode, Chief Commissioner Habaki finds himself in a desperate situation when his connection to Sabaramond is accidentally exposed, leading to his downfall. In his final moments, Habaki ingests a mysterious substance, hinting at a final battle or transformation.

The episode concludes with Polka expressing his excitement about the appearance of elementals—particularly lightning elementals—in the city. His anticipation not only pertains to the unfolding events but also to the arrival of someone from his homeland, foreshadowing an impending convergence of forces both familiar and alien to this world.
