The council's rampage sends quakes through the demon realm, and the demon Chaos is called forth through a giant magic circle. That commander of all heroic spirits flails madly, seeking to claim Basara, Mio, and Leohart's lives. Do they even stand a chance of victory with this supreme being before them?!
Meanwhile, Maria, Yuki, and the others put a final end to their own personal battle.
"Believe in me... once more."
The ultimate sibling combo risks their lives to face the disaster striking all of the demon realm!
At least not until you've 
watched your cute little sister die.
Seht zuerst euren niedlichen

Aún tienes que presenciar 
la muerte de tu hermanita.
Du moins, pas avant d’assister à la mort
de vos adorables petites sœurs.
Non vorrai mica perderti 
la morte della tua sorellina?
Ao menos não antes de ver a
 sua linda irmãzinha morrer.
По крайней мере пока не увидишь 
смерть любимой сестрёнки.
