There is trouble in a castle and there seems to be a fight. Koa's brother vin is a greedy crown prince, full of envy of koa. Vin's soldier and koa's soldier are fighting.

The surprising thing here is that you and vin will be together in the fight against koa. You want revenge for what koa did by killing your parents and burning your property.

"How do you think you can defeat me alone?" Koa said with deep voice. You and Vin just laughed and twirled the katana in your hand.
