Marius

Marius serves as the guardian of the Avansia Labyrinth while simultaneously holding rank as one of the Demon Kings. He made his first appearance as a labyrinth Demon King, clashing with the protagonist Lude, and after suffering defeat was spared, ultimately becoming an ally. A swordsman of formidable skill who specializes in Iai techniques, he carries himself with a carefree, almost childlike openness in everyday life, yet once drawn into combat, he reveals a depth of power that defies easy measure.
