At Aethelgard Magic Academy, status is everything, and being Unranked is a death sentence. Systematically bullied, humiliated, and labeled a "defective core," Vespera silently endures the cruelty of the academy's Rank A elites. With her bruised pride and empty hands, she is treated as a useless vessel incapable of producing even a single spark. But everyone has made a fatal mistake. They mistook absolute stillness for weakness. Vespera isn't powerless. Her core doesn't lack magic-it is the vessel for The Cosmic Cataclysm, an ancient force of the void that ruthlessly consumes magic. She is the destruction itself, a living weapon built to erase entire universes. When the slumbering Cosmic Leviathan inside her finally breaks its chains, it won't just destroy; it will tear reality apart, wiping out every trace of life and swallowing Aethelgard whole until nothing is left but absolute vacancy.
