In her first life, Seren Sol is framed by her sister Elara, her fiancé Damian, and the Holy Council, who steal her astral source and leave her to die. Reborn on the day of Star Academy's entrance trial, Seren conceals her strength, reverses Elara's theft spell, and breaks the false engagement. While investigating the massacre of the Astral order three centuries earlier, she allies with prefect Kain and alchemy prodigy Lyla, connecting a series of drained students to vice dean Aldric. After recovering the lost Astral relic, Seren awakens her full bloodline, destroys Aldric's extraction array, exposes the Council, and reopens the long-sealed Astral House.
