Magic has existed since the dawn of humanity, intertwined with the development and technological advancements throughout the ages. Over the centuries, different cultures around the world have established their own laws, regulations, and social behaviors regarding the supernatural.
In Asia, a network of artificial islands known as the "Golden Cages" was created to contain magicians and individuals with supernatural abilities deemed dangerous to society. It is on one of these islands that our story begins, following Hajime Kamijou, a 17-year-old boy who stumbles upon the power of the "Grimoire of the Fallen"—an artifact of unfathomable and immeasurable strength. This newfound power becomes a beacon for Hajime, guiding him on a treacherous journey steeped in revenge, personal growth, and the struggle for survival in a ruthless and unforgiving world.
As Hajime navigates the complexities of his abilities and the dark forces that pursue him, he must confront not only the external threats that await him but also the shadows lurking within his own heart. His quest will challenge his ideals, reshape his destiny, and reveal the true nature of magic in a world where power can both uplift and destroy.
