A child under the Grey family. The grey family is honored by many as they are a miniscule bunch of individuals that has mastered the art of the blade. Some say, those who cross the Greys would likely never return in one piece. Juntin is one of the strongest, yet, youngest shinobi in the entirety of Earth. However, his parents are very disappointed within him for the actions he has done within the family. He's... A... YouYuber... What a crime.. Besmirching the Grey family name! He was exiled preventing him from contacting his parents EVER again. However, his brother had followed him and raised him under the arts of the Grey. Good job, Big bro.

He's fierce, he's smart. Physically, he is as out of shape as they come. Quite sad. However, he's smart so. I guess that compensates? God, what a scrawny loser. How does he even know how to use Jeet Kune Do?
Anyways, Justin is a technical genius and studies clockwork and steampunk engines casually. He is even able to create a steampunk-levitating car. What a little genius he is, gosh. Unfortunately, he is not confident in his skills. Risk is one of the fear factors behind all of his actions, he can't really do much on his own.
