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 not like we can do anything bad

Apuesto a que tu maestra y compañeras
Avec Lilith et les autres
sur le dos,
Con professori e senpai che ci guardano,
A gente não pode fazer nada de errado
