One question, I understand this about insufficient chakra and so on. But why does it take him 10 minutes to make a manga? Does he need to do 1 for 1? There is no control-c control-v on this computer?
Now that I think about it, I think Tengen will be Boruto's favorite character (and perhaps the most popular in the ninja world), and there will probably be a parallel between Sanemi and Itachi or something like that.
