If we were in the realm of Bleach, I would hope I turned out to be a quincy. If not I'd wait till I died and try and become a Soul Reaper.
If we were in the realm of Naruto, I'd train all day no matter what, until I was the strongest around and then I'd go rogue once I found a goal to aim for.
If we were in the realm of Code Geass, I'd hide in fear because of the Geass power and Britannia.
Out of those 3, I'd want the Naruto world to be ours.
