An assistant of Enma Ai who appears to be a handsome young man with one eye covered by hair. He can manifest a single, very large eye that can be directed anywhere, allowing him to see through walls. This manifests as an eye on a wall. The large eye can also be used as a weapon, by projecting intense flashes of light. When so required, Ichimoku Ren becomes a blue straw doll by kissing a pendant he wears around his neck. He is sometimes referred to as "Moku" or "Ichimoto Ren."
