The Path of Akira

I was a great shadow warrior and died while completing a mission for the emperor's family. But the emperor's spirit gave me a posthumous gift — a new life. However, I found myself in the body of a wimp and a bum, whom everyone considers a disgrace to the clan. Now I am starting my path from a clean slate, and I will prove that Akira Kaneko is a fighter, not a mop. My clan will respect me.
