A boy found during Otsuu's exploration in the underground caverns. Despite his looks, he is a very thoughtful and kind person. He is one of the very few people Otsuu and Little Mermaid encounter that they would consider a friend.

He is usually found guarding the base as the gatekeeper, and supports the Blood Maidens as a handyman of sorts.
He is also a longtime friend of Hikari, and their lighthearted arguments show it.
