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!
I just hope this finally manages to free 
Mio from the demon realm's squabbles.
Ich hoffe nur, dass wir Mio …
Espero que esto libere a Mio de las 
disputas del mundo demoníaco.
Espero que esto libere a Mio 
de las disputas del mundo demoníaco.
J’espère simplement que Mio
Spero solo che questo liberi finalmente Mio
 dai problemi del mondo dei demoni.
Só espero que isso 
finalmente livre a Mio
Надеюсь, теперь Мио будет свободна 
от всех трений в мире демонов.
