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.
You and Lilith-sensei would 
get pretty mad at me, too.
Du und Lilith-sensei wären
wohl auch recht verärgert.
Ustedes dos también se 
enojarían mucho conmigo, ¿no?
Vosotras dos también os 
enfadaríais conmigo, ¿verdad?
Sans compter que Lilith et toi
seriez furieuses !
Inoltre, la professoressa Lilith
 ed anche tu, Mira, vi arrabbiereste, no?
Você e a Lilith-sensei também
 não me perdoariam.
