There's not much/no information about him.

From what I've looked up, he will be a character from "Your Girlfriend," the sequel to Your Boyfriend, with Peter's sister, the yandere, chasing you...😁

A lot of the information is taken from a site strangely different from Wikifandom...

Some information, like the personality and extras, I took from fan art or drawings I found and tried to get an idea of his character...

I'll add design credits and other stuff when I find it...it won't take long
