Following his clash in the Nether with his younger brother Shou, Shinra Kusakabe"s determination to become a savior against the flame menace grows stronger. His objectives—finding a method to restore Infernals to humanity, decoding the Evangelist"s secrets and Adolla Burst, and rescuing his mother and Shou—remain clear. Yet he recognizes that achieving these aims will be difficult, especially given the looming threat posed by the Evangelist.
The Evangelist"s scheme is straightforward: collect the eight pillars—those who hold Adolla Burst—and sacrifice them to trigger a new Great Cataclysm, mirroring the disaster of 250 years prior. After the First Pillar warned him that a new pillar will soon appear, Shinra vows to shield his fellow pillars from the Evangelist. Consequently, a fierce confrontation erupts between the Special Fire Force and the Evangelist. Joined by his comrades, Shinra presses on, uncovering the truth about the Great Cataclysm, the essence of Adolla Bursts, and the enigmas surrounding human combustion.
