Type of Story: Adventure/Fantasy
Based on: Jujutsu Kaisen
Y/n L/n as a young child under Bill Cipher's care (Age 7)

Y/n L/n (Full Power - God Mode)
Y/n L/n and Bill Cipher Fused (Power Level - ???)
Info About the Reader: Y/n L/n was an orphaned child after his parents died and lost his left eye from a knife attack from his abusive and drunk foster father as he completely hated his own life and wished for someone to give him another chance to start over.
That is how he met a strange, yet powerful deity from another world known as Bill Cipher, who was trapped in a void after he was defeated by the Pines Family and failed to take over the world and become a God. Eventually, he soon began to learn from his mistakes after spending a really, really long time in the void and decided to find someone to become his vessel, which is Y/n since he can understand his pain and suffering as well as losing one good eye.
So then, Y/n and Bill have become as one as Bill began teaching Y/n the ways of becoming a God like him and vowed to kill The King of Curses himself, Ryomen Sukuna to achieve the power they both seek to become a true powerful God.
However, after a young man by the name of Yuji Itadori devoured one of the Sukuna's fingers, the King of Curses used Itadori as a vessel to take over when Itadori tried to stop a monster that tried to kill him. So, Y/n used his newfound powers to kill the monster before Itadori had a chance to do it and thus, became a member of an organization after a man named Gojo was impressed by Y/n and Itadori's determination and potential.
It looks like Y/n and Bill Cipher are gonna have to work together to collect all of the fingers of the King of Curses and earn the reputation as Gods of the universe.
Characters
Bill Cipher
Relationship: Father Figure and Mentor
After he lost his chance to rule the universe thanks to the Pines Family in Gravity Falls, Bill Cipher is now trapped in an endless void without his powers to get him out to start all over again. So, he stays in the void for centuries all by himself until he soon starts to realize his mistakes and decides to find a more worthy vessel to become one and teach them the ways of his culture of weirdness to rule the universe once again.
That's how he met Y/n, who ran away from his foster parents along with losing an eye from his drunken father with a knife as he decided to adopt the boy and raise him as his own son.
Overtime until Y/n reaches the age of 19, Y/n has finally completed his surrogate father/mentor's training as he and Bill are gonna do whatever it takes to rule the universe by defeating the King of Curses himself. Even if it means by teaming up with Gojo and his gang to get the power they've been seeking for so long.
Bill will also do whatever he can to protect his own son from danger, even if he sacrifices his power that he had in the past with his battle with the Pines Family or even fuses himself with Y/n to take out their enemies one by one.
This is the first time I checked out this anime series and I'm starting to watch the first few episodes of the series and I'm trying my best to learn more about this series as well as Gojo himself.
I wanted to use a different character that would fit perfectly with the reader, which is why I chose Bill Cipher for this story idea and how he and the reader would form the perfect partnership together in this story.
