Meeting the Pines

Today was your 18th birthday, the day some people may get a demon guardian. You didn't expect to get one but you did. It's a frikin' demon caterpillar named Plixate. You and your new friends have to learn to get along with your demon guardians even if they're freaking suck-y. Demon AU belongs to http://kidsanddemons.tumblr.com/ and Gravity Falls belongs to Alex Hirsch.(The show has already taken place except every episode with Bill.)
