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.
I've stopped it from going further out of control.

Ya no volverá a salirse de control.
J’ai réussi à contenir

Ho impedito che andasse 
ulteriormente fuori controllo.
Eu estou ajudando a 
não fugir do controle.
