Tsuruchi's Yumi was the bow that Tsuruchi, founder of the Wasp Clan, carried all his life. The bow was awakened over the decades that Tsuruchi carried it, becoming one of the most sacred artifacts of the Tsuruchi family. It was kept within Tsuruchi Daimyo's quarters at Kyuden Ashinagabachi at all times unless it was being used during wartime or ceremonies.
