Todoroki has short black hair that is slightly messy and has black eyes. He has a slim build and is usually seen in police garb including the suit he is usually wearing and bulletproof vests.
Todoroki is dedicated to his job but knows when to get help from outsiders including from private investigators. However, he acts rather perverted around attractive and bold women, usually Seiko.
Todoroki often came to Seiko's PI firm to inform her about events that have transpired that leave the police stumped.
