The ultimate demon lord, Astral Trinity, shows up in the form of Arata with a grotesque new appearance. Hijiri appears as well, and the others discover that she is a high-level mage whose goal is to kill Arata and destroy the school.
I can seal all of you in darkness,
Ich kann euch alle in die
Dunkelheit sperren, …
Podría sellarlos en
 la oscuridad si quisiera,
Podría sellaros en la 
oscuridad si quisiera,
Je pourrais tous vous enfermer ici,
Posso sigillarvi tutti nell'oscurità,
Eu poderia selar 
todos vocês na escuridão,
