Yasuki Masami was the Yasuki Daimyo. He dispatched scouts to seek out the rumored surviving nezumi crew of the infamous pirate Yasuki Fumoki after he died in 671. The Crab Clan Champion, Hida Tsuneko, also sought Fumoki's incredible treasures, but they could not be found. The Nezumi were offered positions in the Crab navy due to their great agility, adaptability and cunning, which made them excellent sailors.
