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.
He turned into a demon lord,
Er ist zu einem Teufel geworden
Se volvió un rey demonio
Se volvió un Rey Demonio
Il a puisé dans son énergie magique
après s’être transformé en maître magicien.
Si è trasformato nel Signore dei Demoni
Ele virou um lorde demônio,
e ainda usou magia depois disso.
