Wears a Hyottoko mask on the side of his head. Silky black short hair and a slender build. He looks like an ordinary high school boy in a school uniform. Since the mask is hooked on his head, his face is always visible.

Supernatural phenomena naturally gather around him. He believes himself to be the ordinary "Yuta" and is largely unaware of his own abnormalities.
