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.
If there's an easier way, nothing can beat that.
Ich glaube nicht, dass es schlimm ist,
den einfachen Weg zu gehen.
Así que no creo que esté 
mal tomar el camino fácil.
Así que no creo que esté 
mal tomar el camino fácil.
La méthode la plus facile
est toujours la meilleure.
Se c'è una strada più veloce, 
nulla mi impedisce di prenderla.
Não vejo nenhum problema 
em pegar um caminho mais fácil.
