Board Thread:Theories and Rumors/@comment-30938718-20171214140404/@comment-35879635-20180713155845

Listen, some of the ninja and other main characters just dont have last names. It was not confirmed. Brent Miller has asked on his YouTube channel and the answers were that there simply were none - just rumors. And that goes for the ninja's ages. They've been "teens" for the past seven years.

Although some of these ideas are really farfetched and interesting.
