Urumi wears a loose cow-spotted jacket with black borders over a yellow crop-top with long yellow shorts. She wears sandals and holds a baby-shaped stone in her arms. She has horns like an Oni, though she is not a Hell Oni but an Ushi-Oni. Half of her hair is black, the other half is light grey. She has a light tan and bright red eyes. She also has cow ears and a tail.

"I'm an ushi-oni. I live by the River. If you want to turn back now, I can send you home safely..."— Urumi Ushizaki
