Goyokin

Magobei Wakizaka is a samurai for the Sabai clan. A nearby island, Sado, boasts a rich gold mine which provides plentiful riches for the Tokugawa clan. When one of the gold ships sinks, the local fishermen recover some of it, intending to return it to the clan. However, their clan master, Rokugo Tatewaki, takes the gold and slaughters the fishermen so they cannot report the gold stolen. Three years later, assassins come for him, who is living in Edo, and he returns to Sabai.
