Hiraga Wataru

Jinyou belonging to the 17th Jinyou Pursuit Organization, but he seems to have things to hide too. Contrarily to his appearance he's a remarkable driver.
His ancestor is a youkai called Shirouneri (a youkai species known as an old, rotten dishcloth appearing in the form of a dragon). He can spit a stinking liquid from his mouth, which smells like the aforementioned rotten dishcloth. When vaporized it becomes a non-lethal but poisonous gas.
He has a firm believe in Iizuka Kaoru.
