Now it's Levi's turn to shine baby!

Levi is a demon that came from another realm that wanted to make a deal with anyone with using a page he has put in a strange sketchbook that would be found in a bookshop at Gravity Falls, but the one person that had found the sketchbook is a human named Anna Rodriguez.

Unlike with Bill in the cartoon however and not an antagonist, Levi is a smug ass that always likes to play tricks with Anna, but deep inside of him, he actually sees her as a friend.

While that he has that sort of same personality as Bill from the show itself, Levi is actually being inspired by Shinigami from from Master Detective Archives: Rain Code, meaning that he and Anna are kinda like Yuma and Shinigami if you
actually think about it.
