Times With A Demon. ~Human! Bill Cipher X Reader.~

~Please Read To Get A Feel For The Book And So You Don't Miss Things.~

You had decided to go to Gravity Falls for your last week of summer to visit your uncle Fiddleford, since he'd regained his sanity and moved to a nicer home.
While there you meet some friends and see some silly things.
But the one thing that catches your eye is a rock figure of some one eyed triangle in the woods. The pines twins, Dipper and Mabel, say they have never seen that before. As you three walk out of the woods the wind blows and something hits your leg. As you look down you see an old page that looks somewhat burnt. Picking it up you see an image of the same triangle figure and how to summon him.
Looking at the page you carefully tuck it away and follow after the twins, knowing you might have to go home earlier to test out this summoning thing.
