Giotto was born into what seemed to be a normal family. His mother stood home and was busy around the house while his father was busy working. Although to outsiders his family did indeed seem normal, anyone that closely knew the parents prayed every night in sake of Giotto, hoping that when they awoke in the morning the baby would still be perfectly healthy, and this praying seemed to work until the child was five. At the Age of five Giotto had already started to surpass his academic and physical expectations, which led to his parents submitting him into competition held within Konoha to see which children in the academy were strongest. He fought and fought until finally he was in the finals, matched against what he saw as his only true competition. The kid he was to fight was likewise an uchiha and much like Giotto in sense of skill, however the kid was 2 years older than him. The Uchiha's name was Itachi, and Itachi had just passed his graduation test earlier that day, however due to his ignorant parents Itachi was to remain in the competition.
The already eager Giotto threw a single Kunai at Itachi and soon regretted his decision when Itachi responded by throwing back a barrage of Kunai. Giotto barely managed to dodge what seemed like the last one when he felt his leg get grazed by a kunai that Itachi hid in the Shadow of the other. Since the kunai only grazed Giotto the battle continued, which seemed to slightly aggravate Itachi. After being grazed Giotto stared at Itachi and noticed Itachi had already activated his Sharingan. This deeply concerned Giotto and ended up with him crushing a smoke bomb in his hands. As the smoke covered Giotto Itachi started looking for Giotto's chakra, an ability of the sharingan Giotto was all to familiar with. As soon as Giotto had released the smoke he also released a large sum of his chakra into the atmosphere, causing Itachi to pick up a large amount of activity in his Sharingan. After realizing he had been fooled Itachi released a Fireball at Giotto, however Giotto already left the smoke during that time, jumping in the air soon after releasing his chakre.
While clear to everyone located far enough in the crowd where Giotto had gone, Itachi saw nothing, thinking he had injured Giotto with his fireball as the medics rushed in. During this moment Giotto began to descend upon Itachi, gathering chakra in his hand so he could finish the fight within a moments notice. However his plan was foiled when Itachi's mother saw Giotto and yelled out his position to Itachi. During this moment Itachi spun around to see Giotto inches away from him and instantly pulled his arm back, Knowing he was already too late to dodge or block. Giotto slammed his right fist into Itachi's face, pounding him into the ground, and at the same moment Itachi slammed his left arm into Giotto's stomach, knocking the wind out of the boy. When both of the boys came to it was announced that the match was a draw and Giotto was wanted in the office. Once he arrived it he was told that what he had done was no easy feat and that he was going to be tested the next day to see if he mentally qualified to graduate from the academy, obviously physically qualifying by defeating Itachi. Giotto was overjoyed when he had heard this and thought that no one could possibly make his day any better, and he was right. His day would only get worse from this point on.
When he got home he found his father wasted on the couch, sleeping. He slightly shook his father and asked where his mother was, in which his father replied, in the basement. He went upstairs and dropped the envelope he had received from the academy on his bed and then turned around, heading back down the stairs. He slowly made his way towards the basement, the only part of the house his was not allowed into without supervision, and upon making his way down the stairs he saw his mother tied to a chair, crying with her mouth covered. He quickly ran to his mother and removed the rope that bound her when everything went black. He woke up the next day on the floor with a heavy weight applied to his body. He opened his eyes to find his mother's blood riddled body on top of him. He quickly burst into a panic of tears as he hoisted her limp body off of his own. After getting up he noticed he had also sustained injuries and quickly lifted his mother's body, running her to the hospital. When he made it there the Nurses ran towards him, taking his mother and rushing him to a separate room. They tried to comfort the crying child but could do nothing as the little boys thoughts were filled with the thoughts of is mother's body mangled and sliced. When the nurses left to get the child new clothing Giotto ran back home to inform his dad of what happened.
Upon arriving he saw his dad on the couch with blood stains on his shirt. He ran to his dad crying, thinking he had suffered the same fate as his mother when his dad rose from his slumber. Giotto's father quickly grabbed him and slammed him against the wall, screaming out his wife's name. Giotto then ran upstairs and locked his door, going to the window of his room to escape only to find a bloody note attached. In the note the father stated every gruesome detail of how he had killed his own wife and how he would go to the ends of the earth to erase the existence of Giotto. Frightened Giotto opened the window only to get knocked out by a bystander of the event. When Giotto finally woke up he noticed a large figure next to him and immediately ran, only to smack into the walls of the carriage he was riding in. He then turned to the man and noticed that the man had blue skin and was smoking something out of a pipe. The man explained to him the situation and then told Giotto that his name was Mathias, and that from now on Giotto's last name was going to be Luciano. He also told Giotto that he would be taking care of him from now on and that Giotto was going to be a part of a new family in Yamagakure, where Giotto would train and become stronger. And that is indeed what happened up until Giotto reached the age of 22.
