Majikaja inhabits Iruburu, a village nestled within the Abyss’s sixth layer. Unlike typical hollows, whose forms emerge from natural metamorphosis, his body was manually crafted, reflecting an unnatural divergence from their usual transformation. As a hollow forged from humanity’s defiance against the Abyss, he acts as both guide and mediator for outsiders, navigating Iruburu’s merciless economy where transactions demand sacrifices of flesh or possessions deemed equal in "value."

His expertise spans the village’s history and hierarchies, discerning Nanachi’s origins as a hollow shaped by an older ritual and a lingering human-like visage born of desperate longing. Pragmatism defines his dealings with Riko’s group—halting her impulsive trades, yet aiding her defense of Iruburu during a Luring by reshaping his own form in exchange for strands of her hair. These hunts, where hollows bait sixth-layer creatures to harvest their worth, rely on his vigilance to pinpoint threats and rally defenses, though the village’s readiness often wavers.

Majikaja maneuvers Iruburu’s rigid equilibrium, an automated law enforcing equivalent exchange, advising Riko to exploit her sacrifices as bargaining chips against entities like Belaf. Artifacts intrigue him: Prushka’s white whistle, he insists, must morph into an instrument to awaken its latent force. He speaks obliquely of Faputa, the "Princess of Hollows," whose legend weaves Iruburu’s fate to the Abyss’s deeper mysteries. While his allegiance leans toward preserving the village’s fragile order, his assistance to Riko flickers between calculated survival and veiled, enigmatic benevolence.
