In the chaotic mix of humans and demons, Shu and Kanna meet in a violent clash worthy of their 12-year-gap as various motives intermingle in a battle engulfed by a sea of flames. Ayano, Sharon and Kisara try to somehow intervene in the siblings' fight that puts the fate of the world at stake. The only way to stop a powerful demon is with the power of a demon. Shu and Kisara join hands once again. Will the accumulation of their feelings reach Kanna, embroiled in her rage? At the end of the battle, what future lies ahead for humans and demons alike?
We can't fight that thing
with our equipment anymore anyway.
.لم يعد بإمكاننا قتال ذلك الشيء بمعدّاتنا على أيّ حال
Mit unserer Ausrüstung sind wir ihr
ohnehin nicht mehr gewachsen.
Con nuestro equipo
ya no podemos hacerle frente.
Con nuestro equipo
ya no podemos enfrentarnos a ella.
De toute façon, on ne serait
d’aucune aide contre Kanna.
Ad ogni modo, quella cosa
 è ormai fuori dalla nostra portata.
Não estamos equipadas pra
enfrentar essa coisa aí mesmo.
Всё равно с нашим снаряжением
с ней уже не посражаешься.
