Ippei Hata

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.

Based on the popular story of the tragic lovers, Onatsu and Seijuro.

A fellow member of the company named Hanjiro tells Koharu, an actress in a traveling theatrical troupe, about a keepsake folding fan that his lost love Lady Okyo gave him years ago. It turns out this fan is a precious clan heirloom whose possession, for convoluted reasons, will determine the clan's leadership. Sword-slinging bad guys descend to capture the fan, and Koharu embarks on a road trip to Edo to return the MacGuffin to the rightful hands of Lady Okyo.
