Master of kendo

You've been given a once-in-a-lifetime chance to go to Japan and study the ancient art of kendo, a form of fencing using bamboo sticks. When your martial arts master gives you the good news, he also lets you in on a secret. He has a mysterious sword that once belonged to a famous Japanese general named Hideyoshi. But he refuses to discuss the sword any further with you. Why does your sensei have this sword--and why does everybody else seem to want it? There's not much time to think though--Yakuza gangsters are chasing you down, and you'd better be ready to use your kendo skills!
