(Canon x OC) Bill Cipher x Sapphire: Back Again

((Just let me live in sin.))

Set years after Weirdmageddon struck Gravity Falls, the story takes place in the now peaceful town. A new girl named Sapphire has moved in with her sister, and she's amongst the other quite mysterious and strange people. Upon getting to know Gravity Falls, the purple-haired girl accidentally encounters none other than Bill Cipher, the dream demon whom everyone had thought perished within Stanley Pines' mind. But Bill isn't particularly as "all powerful" as he used to be, and needs Sapphire's help to get back up on his feet again.
