A Dangerous Truth

Bill Cipher is immortal, but (Y/N) "Dove" Cipher isn't. That is a dangerous problem, as Bill is still mentally unstable and everybody fears what Bill will do when (Y/N) is finally dead and they can no longer watch slasher films together.

(Y/N) then decides one thing: They can't die. No, instead, they will embark on a journey across the multiverse to become a demon so death won't do them part. But does (Y/N) have what it takes?
