Kiyotaka Katsuki, 33 years old. He has had an exceptionally keen sense of smell since he was young and absolutely hates anything stinky. He especially detests stink bugs, hating them so much he wishes they would vanish from the face of the earth; when he finds one, he attacks while hurling verbal abuse. When he encounters something smelly, he pinches his nose and writhes in agony. He has slightly wavy black hair and a wild appearance. He is a relentless sadist. When he encounters a bad smell, he reacts loudly with things like "What the—!? So stinky!" "Ugh, reeks!" or "Gah, it's so damn stinky!" He always carries deodorizing spray with him.
