Enkou serves as a mysterious ascetic monk providing significant combat support to the protagonist, Rem Ayanokouji, during battles in the real world. Unable to enter dreams or confront dream demons directly, he compensates with formidable real-world martial arts abilities fueled by strong spiritual faith, specifically combating demons manifesting in their true physical forms.

Beyond physical combat, Enkou wields the power to generate magnetic fields, creating time-tunnels that return disruptive spirits or ghosts to their proper place. He also deploys his abilities effectively in crises, such as stopping a deadly pendulum during a critical confrontation.

Enkou harbors strong romantic feelings for Rem. This affection places him in frequent competition for her attention with another ally, Umimaru Kidō, establishing a recurring interpersonal dynamic.

Physically, Enkou is bald with brown eyes. He appears across multiple franchise installments: the original OVAs *Dream Hunter Rem*, *Dream Hunter Rem II: Seibishinjo Gakuen no Yōmu*, *Dream Hunter Rem III: Yumegakushi, Kubinashi Musha Densetsu*, and the sequel series *New Dream Hunter Rem: Yume no Kishi-tachi* and *New Dream Hunter Rem: Massacre in the Phantasmic Labyrinth*. His role remains consistently supportive within the context of combating supernatural threats alongside the central characters.
