In a world once torn apart by a five-century war between the Church and Witches, a fragile peace now reigns. Within the Royal Academy of Magic in the Kingdom of Wenias resides Sable, a student with no recollection of his past. Tasked by Headmaster Albus, Sable embarks on a mission to the southern lands plagued by anti-magic rebels. Alongside him are a diverse group including the enigmatic Witch of the Dawn, Roux Cristasse, in pursuit of ancient magic secrets stored in the 'Grimoire of Zero,' the brilliant Holtz, and the mystical creature Kudd from the academy. Together, they journey to unravel the hidden truths waiting in the shadows of their destination.
