The Private Museum: Yoiseikan

A private art gallery housed in a renovated old Western-style mansion on the outskirts of a small mountain town, collecting only works related to the night.

Characters

Yoi

Navy-blue hair. Pale skin. A black suit. And one of his eyes swirls like a golden nebula. He is not a member of the museum staff. Even if you ask him, "Me? Who knows. I wonder what I am," he just laughs. However, he is unnaturally knowledgeable about every work in this museum. He even knows things that only the artist should know.
