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!
Once we're back in your room, 
I'll give you all the praise you deserve.
Sobald wir zurück sind,
gibt’s ganz viel Lob von mir!
¡Te felicitaré incluso más 
cuando estemos en tu cuarto!
¡Te felicitaré incluso más 
cuando estemos en tu cuarto!
Tu auras un tas de récompenses
une fois dans notre chambre.
Ci penserò io a ricompensarti per tutto 
quello che hai fatto, una volta in camera tua!
Assim que chegarmos ao seu quarto,
 eu vou lhe encher de elogios.
Вот вернёмся домой, тебя ждёт большая награда!
