Solo Leveling System with Upgrade (indeterminate hiatus-Sorry-)

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?
