[Jujutsu Kaisen] I'm a Skater, So Why Am I on a Sorcery Set?

Gu Mujia is a skateboarder and a cosplayer. He was supposed to be playing a character on the Little Skateboard set, so why has he ended up on the JJK set? Isn't something a little off here? Sure, this is a personal setup using JJK's worldbuilding, but could the dimensional wall please be a little sturdier and stop getting broken so easily? Gu Mujia is speechless. Still, since he's lucky enough to have come to this world, he hopes he can get what he wants. Theme: You have infinite possibilities.
