Spectre of Konoha

I tried to help a kid that was drowning in the lake. For my heroic actions, I lost my life. But that doesn't mean everything is over. I got a second chance in the world of Naruto. It's kill or be killed and I really don't like to be killed. Easy to say but how will I survive when I am surrounded by assassins, maniacs with the idea of putting the world in a dream to achieve peace.
