Attending classes, battling evil spirits, and dealing with stuck-up nobles whose names are longer than my backstory.But something’s off. My mana doesn’t behave like theirs. The world listens when I speak. And the whispers I hear at night? They’re getting louder.They say evil spirits wander through Ashgrad under the light of the moon. And I think they’re looking for me.They think I’m a failure.Maybe I am.But if this cursed academy wants to survive the next full moon, they might just have to rely on me — the last-ranked summon with a dangerous secret.
