It's the last episode, and Hijiri and Arata have their final showdown. Lugh joins in the fight, along with the Trinity Seven--Lilith, Levi, Arin, Mira, Akio, Yui, and Liese. Why is she attacking Arata? And what secret does Arata hold?
I've seen the demon lord destroy 
the world over and over again,
Ich habe den Teufel die Welt wieder
und wieder mit den Trinity Seven
He visto al rey demonio destruir 
el mundo incansablemente una y otra vez.
J’ai vu le monde périr
encore et encore
Io ho visto tante, tante volte
 il Signore dei Demoni e le Trinity Seven
E eu vi o lorde demônio destruir
 o mundo de novo e de novo.
