Solo Leveling System with Upgrade

A guy is accidentally killed by God when he tries to change his luck or rather his lack of it. As retribution God lets you reincarnate in a world of your choice and create your legend or harem. The first world was Naruto, which ones will be next?

IMPORTANT: I have no copyright on Anime Naruto and none of the anime worlds that appear in this story, I'm just an ordinary guy who is making a story half a mouth for hobby
