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 mean, it was my first kiss with a boy,
Ich meine, es war mein erster
Kuss mit einem Jungen,
También fue mi primera 
vez besando a un chico,
También es la primera 
vez que beso a un chico.
C’était mon premier baiser
avec un garçon,
Era la prima volta che baciavo un ragazzo,
Quero dizer, foi meu primeiro beijo,
