To protect the man who saved you, the only family you have, is an honor and you will do everything and anything within your ability to do so. You've spied for him, you've delivered his messages, you've killed for him. There is nothing you wouldn't do, So when you caught the whispered rumors of a man treading through Japan on a path of destruction and murder headed straight for your father you knew something had to be done. You'll stop him on this path, and get to him before he can even lay a finger on your father. You'll stop this blue eyed demon no matter the cost.
