Showed up at Kasuga's shuriken tournament and lost. Later that night he, Juro and Hanzo jumped Toru in an alley, mocking and beating him up.
He was next seen at a nearby restaurant with several other young men. They refused to pay and when the owner insisted, he flashed a shuriken from his sleeve and quietly threatened the man. Toru intervened, resulting in a brawl that saw one of Yasu's companions dead.
Identified as one of Sho's apprentices.
