Before birth
Over three hundred years ago it seemed that Itachi had a fling with another Uchiha member, months before he was ordered to massacre the clan. When Itachi was given the order to massacre the clan it turned out there was two other people from the clan he couldn’t kill, his girl and his unborn son. Telling her to flee from the village so she wouldn’t die, she of course did as she was told and fled never to see Itachi again. A few months later the women gave birth to a boy who grew up with his mother never activating his sharingan. After years of breading with people that weren’t from the Uchiha the family believed the small amount of Uchiha blood in there veins would make it impossible to activate the sharingan.
Birth
Almost 300 years after Itachi’s son was born yet another male was born into the family, the mother chose to name him Mangetsu after the moon. For years he grew up with his mother and father in a small village to the south east of the time village. Mangetsu grew up happy until one day when his father grew angry at his mother and began beating her. But what his father didn’t know was Mangetsu was in the next room watching through a crack in the door, after watching his mother nearly beat to death even with the small amount of Uchiha blood still left in his veins he activated the sharingan. In a uproar he attacked his father with one of the kitchen knives killing him. Minutes later his mother died in his arms. After both his parents dying he fled his home and joined the academy in the time village.
Academy student
After joining the academy he immediately went into his studies, learning how to manipulate his chakra, and how to use taijutsu, Ninjutsu, and Genjutsu. After years of training he realized the cops where still looking for the murder of his mother and father, so he begged the time kage to give him a personal genin exam. The Hitotokigakage accepted his request not knowing that the second he was given his head band he planned to flee from the village. Mangetsu easily graduating he took his head band and jumped out of the kage tower window and fled from the village.
