The group are still on their way to Edo for the tournament but Tsubura is kidnapped by the Yagyu clan who believe she is heir to the Mutsu Enmeiryu. However, it soon emerges that Tsubura is not who she appears to be. In fact she is only using the Mutsu name so that she can get close enough to the Shogun to kill him. But luckily for Tsubura the real successor of the Mutsu name is close at hand. We are also introduced to Jubei Yagyu a very dangerous and accomplished swordsman.
