Kobeni is a petite young woman with short brown hair, in both the anime and colored manga, tied in a ponytail. She has brown eyes with white pupils. On her face are four moles, two under her left eye, one on the lower right side of her mouth, and one on her left cheek. She normally wears a professional suit and she has two hair clips. At the newbie welcome party, she wore a hand-me-down dress from her older sister which was considered to be cute by a couple of other Devil Hunters.
