Captain Kishibe is a Public Safety Devil Hunter from Tokyo Special Division 1.

Kishibe is a grizzled man with scraggly facial hair and a stitched scar running across his left cheek from his mouth. As a young adult his hair was black, but has since then become grey. With two piercings on his left ear and one on his right ear, Kishibe normally wears the standard Public Safety Devil Hunter uniform with a large overcoat.
