Owl holds the rank of chief in ACCA’s Inspection Department, managing district-wide compliance audits through his deputy, Jean Otus, as severe motion sickness restricts his direct involvement. Behind this bureaucratic role lies his concealed past as Abend, ex-captain of the Dowa Kingdom’s Royal Guard, once entrusted with safeguarding Princess Schnee. After aiding her staged demise, he adopted the Owl persona to discreetly oversee her children, Jean and Lotta Otus, shielding their royal heritage from public exposure.

Operating through Nino—a subordinate linked to his royal past via Nino’s father, who chronicled Schnee’s life—Abend orchestrated covert operations, including suppressing evidence post a fatal train accident involving Jean and Lotta’s parents. This erased traces of their lineage, preserving secrecy. His dual existence as Owl and Abend intertwined ACCA’s administrative oversight with clandestine guardianship of Dowa’s legacy, positioning him as a linchpin against destabilizing forces.

Loyalty to King Falke II and the monarchy’s preservation drives his maneuvers amid brewing political unrest, including coup threats. Though he maintains a detached professional rapport with Jean, their interactions subtly echo his unspoken vow to protect Schnee’s heirs, prioritizing duty over personal bonds until schemes endangering the kingdom’s equilibrium are neutralized.
