Arata Kasuga

Arata Kasuga is a 17-year-old whose ordinary life was shattered by the mysterious 'Collapse Phenomenon,' which claimed everything he held dear—including his beloved cousin Hijiri. Driven by an unshakeable resolve to bring her back, he enrolls in the Royal Biblia Academy to master the arcane arts. Born with the rare 'Demon Lord Factor,' Arata possesses an extraordinary power to dominate and nullify magical forces, marking him as a true candidate for the Demon Lord throne. Though he carries himself with a carefree, flirtatious attitude, the heat of battle reveals a razor-sharp mind and unwavering determination—qualities that make him the undisputed soul of the Trinity Seven.
