Yasuki Kappako was a merchant of the Crab Clan at Kalani's Landing, in charge to gather jade for their clan's never-ending war with the Shadowlands. He clashed with Daidoji Iyashi, who was eager to acquire jade for his merchant patron Doji Chonitsu. Yoritomo Hokare had also sometimes gotten into mercantile tussles with both Daidoji Iyashi and Yasuki Kappako. Kappako was reputed as the more skillful, but Iyashi was by far the richer, and was rumored to have sponsors in the Second City.
