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.
No matter how high level the magic,
Egal, wie stark die Magie ist,
No importa cuán alto sea el nivel de 
tu magia, si no puedes controlarla,

La meilleure magie du monde
n’est efficace que si elle est maîtrisée,
Non importa quale sia il tuo livello di magia,
Não importa quão grande
 seja o nível da magia,
