You have been training in an open field for almost 10 years, working on your fighting skill with your katana. You have always wanted to become one of the best samurai in Tokyo, but you couldn’t seem to improve.

One day, while you were training in the field, you began to get frustrated. As you slashed at a piece of wood, the blade of the katana recoiled and slashed your cheek.

“Need help?” A voice said from behind you. You didn’t even hear his footsteps as he walked closer. A black mask covered his nose and mouth. A special-made katana was in his hand. His fox tail flicked behind him.
