Eiji Hoshimiya, a 17-year-old high school student with piercing light-blue eyes and short black hair, bears an Order Mark etched into his left palm—a symbol of his burden. Framed as the architect of the Great Destruction a decade earlier, he concealed the truth: his stepsister Sena, driven by a wish granted by the enigmatic entity Daisy, triggered the catastrophe. Eiji’s own wish to shoulder her guilt awakened his power to steal memories and abilities from fellow Order Users, even claiming Sena’s Domain Expansion. Withdrawn and detached, Eiji shuns school life and human connection, fixated solely on protecting Sena. Her terminal illness and guilt over the Great Destruction fuel his desperate quest for atonement. Though he resists violence, his devotion pushes him to teeter on the edge of global ruin if it means saving her. Bound by Daisy’s restrictions, his Order initially operates at a fraction of its potential, enabling dominion over those within his territory through spoken commands. As his power evolves, he manipulates gravity, air, and matter—yet inconsistencies in its rules, like visibility or sound dependencies, leave vulnerabilities. His relationships mirror this complexity: Kurenai Rin, an immortal assassin whose vengeance softens into tentative affection, and Iyo, whose unwavering loyalty masks unspoken romantic longing. Gennai Hoshimiya, his father, masterminded the Great Destruction by twisting Eiji’s self-sacrificial wish, catapulting him into a global conflict. Their eventual clash exposes irreconcilable ideals, culminating in reality-altering confrontations to heal Sena. Exiled alongside her for three years post-resurrection via the Group of Ten’s collective wish, Eiji returns to unresolved tensions with Rin and Iyo, both pledging to vie for his heart. His journey traces a reluctant hero’s struggle to reconcile power’s corrosive allure with the fragile hope of redemption, etching themes of sacrifice and responsibility into every choice.
