Although he does not appear until the events of the Boruto manga, he did exists before it and would be a great addition to the number of Uchiha characters that are available. Shin’s unique abilities would make for some very creative justus. Just think about it lol.
This isn’t in the correct place on our forums. Also, there are 31 characters (most of which are open) and I have no intention of adding more. Just adding characters is kind of an uniformed idea and doesn’t fix or help fix problems we currently deal with. Thanks for the suggestion though.
