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!
And here I was letting you all live 
out of the profound kindness of my heart.
Und ich hab euch noch aus reiner
Gutherzigkeit weiterleben lassen …
Y yo que tuve la cortesía de 
dejarlos vivir todo este tiempo...
Y yo que tuve la cortesía 
de dejaros vivir todo este tiempo.
Vous n’étiez en vie que grâce à l’énorme
indulgence dont j’ai fait preuve.
E io che volevo lasciarvi vivere, presa 
dall'immensa bontà che dimora nel mio cuore.
Logo quando eu estava deixando 
vocês viverem por pura benevolência.
А ведь вы живы были только 
благодаря моей безмерной доброте.
