Nice start, here are some recommendations. Keep the harem to a minimum of 3 to 5, that way everyone gets their chance to shine. Are there canon events that Naruto would face? Since he’s about defying fate I think he would take that fate and shove it where the sun don’t shine. Also, a system would make him too broken, I think he’s fine with the shadow clones, super solider serum and spider man abilities.
FanFic_Listener:thanks for the review, I do agree with keeping the harem small and as for the system I was thinking of making it a "progression system" or "dexterity system" where it shows the abilities that he chooses to master instead of a reward type of system. "you have maxed level on reading speed" or whatever.
