Sid and Ruki
Ruki has blond hair, with thick bangs that go over her left eye. The hair on the right side of her face is pulled back into what appears to be a small tail.
Her outfit consists of a thick-looking beige cloak, with stitchings scattered all across the fabric, as well as eyeball-like ornaments with yellow pupils. The tails of her cloak appear to have at least three mouths, with large teeth and yellow tongues.
She wears a white eye patch over her right eye, as well as a pair of headphones, which feature an eye design.
- Some fans think she is a boy.
