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?
When that happens, I'll take over
and protect the autonomy of the City.
.عندها سآخذ مكانكم وأحمي استقلالية المدينة
Falls es so weit kommt, sorge ich dafür,
dass die Autonomie der Stadt gewahrt bleibt.
Yo protegeré la autonomía
de la ciudad por ustedes.
Yo protegeré la autonomía
de la ciudad por vosotros.
Je prendrai la relève
pour gouverner la ville.
In quel caso, prenderò il comando
 e proteggerò la nostra indipendenza.
E se isso acontecer, eu assumo para
proteger a autonomia da cidade.
И тогда я, как заместитель,
защищу суверенитет города.
