Anteki was the son of Korai Urushi, a modest rice merchant in Iiso. However, when Anteki was young, customers mysteriously stopped going to his father's shop. Ruined, Urushi sold his business to Osahichiro Yoto, Iiso's largest rice trader.
Anteki became convinced that the ruining of his father's business was a government plot and joined a machi-yakko group. In time, he became the leader of the group thanks to his skills and started a private war against the local businessmen, especially Yoto.
