When I was first reincarnated I did the very first thing any self-respecting man in my place would do. Check to see if I still had my balls. I did. The next thing I did was try to get my hands on some power. True Power. I chose the Rinnegan. And if I had to kill a few people along the way to get it, well, there was a war going on. No one will notice an extra body or two turning up.
