Jason was a dropout and a failure. His whole life has even a series of misfortune one after another. In elementary school, he was bullied by a girl. In middle school, he failed all his classes. Then he got to high school and barely passed the 9th and 10th grade after studying every night.
He decided that he couldn't do it anymore so he quit high school to become a SoundCloud rapper. He spent a 6 months doing this whole living off of his parents and failed so he was forced to get a job at McDonalds.
One day he was waiting for his parents to pick him up when a car hit him and he died.
Later he woke up and was in a empty dark space. The a voice rang out, "HELLO JASON, I've been watching you and I thought you were such a loser so I will give you one more chance at life. Choose any world you want to be reincarnated into and good luck."
Jason was think for a while and asked, "Can it be a anime world."
"Yes I said any world f*cktard. Listen. Now hurry and choose." The voice replied.
Jason continued to think while ignoring the comment. He's always loved One Piece and Naruto. It was a hard choice. He thought and asked, "What timeline will I be reborn in and who will I be?"
"It will be all randomizes." The voice said.
"Then I will choose the One Piece world." He chose this world because there are Devil Fruits which if he manages to find one he will be extremely strong.
"WELL GOOD LUCK AND DON'T FUCK IT UP AGAIN CONSIDERING HOW YOU KNOW MOSTLY EVERYTHING SINCE YOU'VE READ AND WATCHED EVERY CHAPTER THAT'S BEEN OUT."
