The Special Fire Force Company 8 is rescued after escaping from the prison by Benimaru (disguised as "Moonlite Mask"), who repels the White Clad with his ability to control heat in the surrounding area. Meanwhile, Obi reveals that Burns sacrificed himself to pass the responsibility of saving the empire to Shinra. The 8th Company finds temporary shelter in Asakusa, where Benimaru critically questions the alliance between the empire and the White Clad.

In parallel, Burns' death is officially declared as "murder by the 8th Company," branding them as enemies of the state. Karim (2nd Company) and Huo Yan decide to uphold Burns' legacy, while Hibana (5th Company) investigates the ruins of the St. Raffles Convent—the orphanage where she and Iris grew up. There, she discovers a secret underground laboratory documenting experiments with doppelgängers and connections to Adolla energy.

The episode culminates in the revelation that the convent served as a testing ground for the White Clad to create "human pillars." When Hibana, Karim, and Huo Yan encounter Sister Sumire—a doppelgänger from Hibana's past—it becomes clear that the White Clad systematically manipulated nuns to prepare for the Great Cataclysm.

The episode ends on a cliffhanger: Sister Sumire, now an Infernal doppelgänger, confronts Hibana and hints that the truth behind spontaneous human combustion is deeply rooted in the convent's experiments. Meanwhile, Haumea schemes in the background, planning the final phase of "rebirth" through the unification of all Adolla Burst bearers.
