The first series featured popular actor Muga Takewaki, a co-star in the network's program Ōoka Echizen, which alternated with Edo o Kiru in the same time slot.
He played Hoshina Masayuki, half-brother of shōgun Tokugawa Iemitsu, masquerading as Azusa Ukon in a good-over-evil drama set in Edo.
In this version of the Kin-san story (which has been the subject of several other series), Kinshiro lived in the house of the woman who had been his nursemaid (played by Masumi Harukawa, later O-Sai of Abarenbō Shōgun), the proprietor of a fish-dealer.
Wearing a purple cloth over her head and face, and wielding a sword in the Yagyū Shinkage-ryū manner, she works outside the law to bring justice to the wicked.
A major cast change brought veteran jidaigeki actor Kōtarō Satomi to the lead role, again as Kin-san, for the seventh and eighth series.
