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!
Then if we break the barrier 
and reunite with the others...
Und wenn wir die Barriere durchbrechen
und wieder zu den anderen stoßen …
Pero si rompemos la barrera y 
nos juntamos con el resto...
Pero si rompemos la barrera 
y nos juntamos con el resto...
Et si on brise la barrière
pour rejoindre les autres ?
Se infrangessimo la barriera
 e ci riunissimo con gli altri...
Então se destruirmos a barreira 
e nos reunirmos com os outros...
Тогда можно разбить барьер и 
объединиться с остальными...
