The Mikado reigns as New Yogo’s absolute sovereign, wielding dual administrative and religious power as heir to a mythic prince who vanquished a water demon to establish the kingdom. Bound by ancestral tradition, he adopts the title “Mikado” upon coronation and submits to rigid customs forbidding foreign language use or travel beyond national borders.

Father to princes Sagum, Chagum, Mishuna, and Tugum, he initially sanctions Chagum’s assassination after royal seers declare the prince possessed by a drought-bringing water demon—a choice driven by duty to safeguard his realm despite private anguish. Following Chagum’s reported demise, he mandates public veneration of the prince as a martyr to uphold the monarchy’s image.

When evidence surfaces of Chagum’s survival and potential innocence, the Mikado tentatively offers to restore him as heir after Sagum’s untimely death. Upon Chagum’s return, the ruler reframes his son’s ordeal as a heroic triumph over the demon, mirroring the kingdom’s founding legend to reinforce stability. Yet Chagum’s rising popularity stokes the Mikado’s distrust, spurring a failed second assassination bid. His dismissal of warnings about an approaching calamity culminates in his own demise.

The Mikado’s three consorts include the First and Second Queens, mothers to Sagum and Chagum, and the Third Queen, mother to his daughters. His rule oscillates between cold statecraft and conflicted paternal loyalty, consistently prioritizing political imperatives over kinship. Governing with calculated authority, he increasingly succumbs to suspicion toward perceived threats to his power.

His arc underscores the paradoxes of leadership, where moral compromises for collective security ignite crises. The Mikado’s legacy becomes inseparable from New Yogo’s mythic identity, illustrating how rulers mold history and familial bonds to consolidate authority.
