Enkou is a prominent supporting character in New Dream Hunter Rem: Massacre in the Phantasmic Labyrinth, where he serves as a mysterious ascetic monk and a key ally to the protagonist, Rem Ayanokouji. His role is primarily that of a combat specialist in the real world, as he is unable to enter dreams or directly confront dream demons within the dreamscape itself. To compensate for this limitation, Enkou possesses formidable real-world martial arts abilities, which are fueled by his strong spiritual faith and are particularly effective against demons that manifest in their true physical forms.

Beyond his physical prowess, Enkou wields unique supernatural powers, most notably the ability to generate magnetic fields. This power allows him to create time-tunnels which can return disruptive spirits or ghosts to their proper place and time. He has demonstrated his resourcefulness in critical situations, such as using his abilities to stop a deadly pendulum during a confrontation, and working alongside an ally to safely dispose of a bomb disguised as an apple.

In terms of his personal motivations, Enkou harbors strong romantic feelings for Rem. This affection creates a recurring and significant interpersonal dynamic, as it places him in frequent competition for her attention with another of her allies, the parapsychologist and scientist Umimaru Kidō. This rivalry is a consistent aspect of his character. Physically, Enkou is depicted as bald with brown eyes.

Within the story, Enkou's function is consistently to provide essential support during supernatural threats that occur in the real world, acting as a guardian and fighter alongside Rem and the other members of her team. No significant character development or transformation for Enkou is documented, with his role remaining static as the spiritually-powered, martial artist monk who is a loyal and romantically interested ally to the protagonist.
