Shinra is overwhelmed and loses consciousness. The next time he wakes, he's tied down in an unfamiliar room.

Fire soldiers race out to fight two pillars at once. Benimaru spots a certain Infernal near one of the two.

Gazing up at a strange moon, Licht has several realizations. Sho strives to find out about his family.

The last pillar appears. As the 2nd battles, nightfall brings darkness and despair. Then, a ray of light...

Shinra, Sho, and Iris have vanished! The 8th sets out to look for them and someone unexpected offers to help.

The 8th marches on Amaterasu. Vulcan's team investigates inside while the rest hold the White Clad at bay.

The Great Cataclysm begins. Fires erupt. Cries of despair rise. What action can the Fire Force take now?

Colossal fires throw the Tokyo Empire into chaos. Cries of despair from the people spread until they threaten to swallow the Fire Force soldiers, too. At that moment, Obi encourages his comrades to rise up. His words get the fire soldiers get back on their feet, and they begin rescue operations to bring hope to the people. Then, as if to mock them, demons who bring despair to the world appear.

Seeking to settle the score from their last meeting, Arthur challenges Dragon to battle alone. Their fight rages over land, sea, and air. And then, they travel to the surface of the strange moon. In the airless vacuum and extreme cold, Arthur desperately fights back, but then, at last, he collapses. The fate of the world hangs on this battle. Will the Knight King, Arthur, be able to win?

Arthur has exorcised the great despair. Just as everyone wonders if the Great Cataclysm has stopped, the moon begins falling toward Earth. At the same time, Kurono and Joker face off against their doppelgangers. And then, the "strongest demon" also appears.

Shinra and Sho confront Haumea in Adolla. Haumea believes that humanity's collective unconscious harbors a wish for death. She kills Inca and Sumire right in front of Shinra and Sho. The brothers reject Haumea's words and launch an attack, but for some reason their blows don't reach her.

Shinra's rage and despair spark the transformation of the earth into a second sun. With humanity's wish fulfilled, Haumea prays for her own death. Shinra faces her with a demonic expression, intent on killing her. Then, a huge flash of light strikes from space! The battle between the saintess (Haumea) and the hero (Shinra) reaches its climax!

Shinra is overwhelmed and loses consciousness. The next time he wakes, he's tied down in an unfamiliar room.
