Ōmi Ikeda, half-brother to Chikae Ikeda, is entangled in a legacy of violence sparked by their father’s assassination via a supernatural curse. Once embroiled in a conspiracy against their father, he later turned his schemes toward their mother, shadowed by private ambitions. When the plot collapsed, he broke from the conspiracy’s ranks, carving a solitary path that occasionally aligns him with the protagonists as a provisional ally.

His dynamic clashes with Tsukasa Kenmochi, Abe no Seimei’s descendant, stem from opposing philosophies on magic and morality. Adopting the alias “Dragon King,” he wields sophisticated arcane arts while concealing his identity behind a mask, rendering him both a potent adversary and an erratic wildcard. His command over esoteric forces enables him to pivot between cooperation and antagonism, guided by shifting objectives.

Born into a family of political and economic prominence, the curse that shattered his lineage ignited his pursuit of occult ascendancy. Though his early schemes exploited spiritual machinations for personal ends, his later trajectory veered toward self-directed ambitions. He intermittently collaborates with the protagonists, their partnerships tempered by mutual adversaries.

Expanded narratives, including the *Sendai Kokeshi Enka* OVA and spin-offs, frame him as a gray-shaded enigma, his tactical brilliance and mystical prowess clashing against the protagonists’ tactics. The prequel series *Sukuna o Koroshita Kami-hen* illuminates formative influences behind his defection and motives, his story revolving around rivalries and alliances laced with ambiguity.
