In a world ruled by magic, where grimoires choose their wielders and kingdoms rise and fall by arcane might, a girl appears from the ashes of a forgotten village—bearing a grimoire that should not exist.
Astra Nocturne, a mysterious orphan raised in the shadowed fringes of the Clover Kingdom, manifests a Seventh-Leaf Grimoire—a mythical tome said to contain the last breath of creation itself. Neither wholly divine nor demonic, her power bends the very laws of magic, making her both revered and feared.
Haunted by a traumatic past and hunted by those who wish to exploit her, Astra joins the Black Bulls, a misfit squad of magic knights. Her stoic presence, unmatched power, and celestial beauty quickly turn heads—but it's Noelle Silva, proud and guarded, who finds herself drawn to the strange girl who never flinches, even in the face of death.
As Astra begins to unravel the truth behind her origin, a new threat emerges: The Eclipse Coven, a clandestine order of forbidden magic users led by none other than Selene Nocturne, Astra's long-lost sister. The Coven seeks the Origin of All Magic, an ancient relic capable of rewriting the laws of existence—by unmaking the world and building it anew.
Torn between loyalty to her new family, unresolved love blooming in her heart, and the pull of blood that binds her to Selene, Astra must make a choice: save the world that shunned her… or let it burn and begin again.
