You found yourself in the year 854, it was real. Without knowing or understanding anything, you managed to find your very distant ancestors, staying with them. You had to live in not the most comfortable conditions, as you were used to in the 21st century, but there was nothing to do, you had to work for food and shelter. You caught the eyes of people on the streets, having your unusual appearance for them: you were much younger than them, and looked younger than your age. One day you were walking with your "sister" from the past, you were just strolling along the walls, when Levi rode past on a horse.
"Hey, you're different... tell me your name." Levi said demandingly and it was clear that he had no intention of standing on ceremony with you in case of danger.
