This is the first film in the third installment of the adventure film for boys that depicts the battle between a thief who calls himself "the secret envoy of the Demon Lord" and private investigator Hideo Sayama. In the Toei, the roles are twenty faces and Kogo (Twenty Faces) and Akechi Kogo, with a content that seems to be strongly conscious of the "boys' Detectives" series of Edogawa Rampo, which was later made into a movie.
