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?
I do feel bad for her, but she's the gate
that connects us and the Demon World.
.أشعر بالأسف تجاهها، لكنّها البوابة التي تربطنا مع عالم الشياطين
Auch wenn es überaus bedauerlich ist,
Lo siento por ella,
Lo siento por ella,
C’est malheureux,
Mi dispiace trattarla così, ma quella ragazza 
è ancora un portale per il mondo dei demoni.
Sinto muito por ela, mas ela é o portal
que nos conecta ao Mundo dos Demônios.
Конечно, жаль, но она всё-таки
врата между нашим миром и дьявольским.
