Justin Kent

Justin Kent is a human character that has been confirmed by 2Gamma to appear in a story. It is unknown if this story will be a solo story, a story with Zack or a story with Julius. However, his appearance has been briefly described as "Late teens or early twenties, kinda cute but overall very strong, wears shirts with pictures or text on them, has a hat."

Theories
Justin Kent may be named after Justin Hunt, one of 2Gamma's old TF-loving friends from deviantART. If this is the case, he might have something to do with TFs.

He might appear in the TUA series.

Justin Kent's description makes him seem as if he would fit well into a sequel of Welcome To Krieneville, however, that story had a pretty happy and conclusive ending, so a sequel is unlikely. However, there may be a sequel, since the TUA Universe crew is unpredictable.
