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'll invite you here again after my magic stabilizes.
Ich lade euch wieder ein,
sobald sich meine Magie festigt.
Volveré por ustedes cuando 
logre estabilizar mi magia.
Volveré a por vosotros cuando 
consiga estabilizar mi magia.
Je reviendrai quand j’aurai digéré
mes nouveaux pouvoirs.
Vi richiamerò qui una volta
 che la mia magia si sarà stabilizzata.
Eu vou convidar vocês de novo 
quando minha magia se estabilizar.
