Back In Time

(I am creating this for fun so don't expect normal updates :) I also don't own Naruto or Boruto and I don't own the cover either so if creator wants me to take it down, by all means I'll do just that. This story is a little bit like one that already exists so if it seems that I'm taking your ideas I'm sorry) What if four individuals was sent back in time? What if three of those four got turned into little children? What would they do then?
