Liese, the last Trinity Seven, appears in the Eternal Library bearing a demon lord seal, making her a demon lord candidate, as well. She tries to entice Arata to join the evil mage side to help save Hijiri, and kisses Arata while he's unsure what to do. Arata has his magic stolen from him, and Liese decides to attack the school.
It's a shame Lilith isn't here to 
slap you with a comeback.
Bedauerlich, dass Lilith nicht hier ist,
um etwas zu entgegnen.
Lamento que Lilith no esté 
para decirle un par de cosas...
Lamento que Lilith no esté 
para decirle un par de cosas...
Dommage que Lilith ne soit pas là
pour vous donner la réplique.
È un peccato che Lilith non sia qui
 per darle uno schiaffo.
Sinto muito que a Lilith não esteja aqui 
para falar umas coisinhas pra você...
