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.
Well, you took Hijiri's place by taking 
her form while she was gone, right?
Nun, du hast Hijiris Platz eingenommen,
während sie fort war, oder?
Bueno, te encargaste de mí todo el tiempo 
que Hijiri no estuvo conmigo, ¿cierto?
Bueno, te encargaste de mí todo el tiempo 
que Hijiri no estuvo conmigo, ¿no?
Mais oui,
No, vedi, ha preso il posto di Hijiri mentre era via, no?
Bom, você ficava no lugar da Hijiri 
quando ela precisava sair, né?
