Overview

Den Shichi of Kurodomon-chō, the best detective in Edo, captured members of a thief gang called "Kitsutsuki," but let three, including the rōnin Daikoku Yajūrō, Tengai Omachi, and Kasumi no Seiji, escape. Among the captured who were exiled, Genta and Kakuroku broke out and returned to Edo to reorganize the Kitsutsuki gang, starting to wreak havoc in the city. Due to the brutal methods used, Den Shichi suspected Yajūrō and Omachi had rejoined the gang. One day, a child who saw a hairdresser resembling Den Shichi, named Kiyoshi, reported to him. Kiyoshi, trusted by the moneychanger Yamano-ya, frequented by Den Shichi's wife Oshun, was rumored to be in love with Yamano-ya's daughter Oiku. In fact, Kiyoshi was Kasumi no Seiji, now living an honest life.
