Just like Soumei he can transform into a wolf, him being red. Formerly, he worked for the police but quit and formed his own detective agency after his younger brother, Haruka, left. His former partner is Kuniharu Ogino. He still continues to help him in cases, ones that involve the Valentino Family.
