The Travelling Demon is a character who is hired by Kurama to scare Naoko Sakurai into admitting that she was the perpetrator in a crime. After telling the Spirit Detectives that he was glad to help, he hops away, but not before telling Yusuke and Kurama that he will soon be on TV.
He seems one of the few lower class, weaker demons without any evil intentions whatsoever.
He seems to be from the country based on his accent and clothes.
