In a hospital room in konoagakure, you could hear the screams of Akemi Uchiha as she was giving birth. Next to her her husband Atsuhiko Uchiha was holding her hand.
The midwife seeing the head said " Keep pushing I can see the head!"
Akemi did as she was told and kept pushing while crushing the hand of her husband until they heard the cry of the baby. " This is a good and healthy boy ! Have you already decided his name ?"
Akemi replied smiling " Yes you are holding Kyokai Uchiha." then she continued " Atsu, would you bring Dan inside to see his little brother please."
He hurrieedly left the room and came back 5 seconds later with a 7 years old boy. Then the boy, Dan Uchiha walked slowly throught the room and extended his arms to his mother, asking smilingly" Can I hold him ? Please mom !" He began to panic seeing his mother's face saying no. But then Akemi face revealed a warm smile " Of course you can Dan, it's just so funny and easy to tease you."
Dan blushed knowing his mother teased him in front of other people, but nonetheless he carried his little brother smiling at his little cute face "Hi Kyo, it is your big brother speaking to you,.. Haha yes it's me" Dan laughed as Kyo grabbed his nose. "See mother, father, Kyokai already recognised me !" he said proudly. Both his parents laughed seeing this.
Kyo's family began to attract attention as Kyo was considered as a bit of a prodigy as he began to walk and talk at 6 months and could run and read only being a year old. Seeing this his parents decided to begin his training ahead of time when he was a year and a half. His mother being a medic she helped him with his control over chakra and to determine his affinity with the elements. He turned out possessing affinity with 3 different elements being fire, lightning and wind, which only increased his reputation as a genius. He was able to walk on water with the same proficiency as on earth at 2 years old, making his control over his chakra outstanding. Then he began to practise kenjutsu (Swordmanship) and shurikenjutsu with his brother and his father who was a jonin.
Many people not acquainted with Kyo thinks Kyo is very arrogant and feel superior because of his talent and thus dare not approch him but people close to him, as few as they are, know that he is quite the opposite of the rumor. This is because everytime he is getting arrogant, his father or his brother would beat him up to.
Now, Kyo was five and was in one of the Uchiha training grounds, opposite to him was his brother who now was twelve years old and a chunnin. He suddenly launch himself toward Kyo very quickly taking his sword out. Kyo certainly didn't just sit there doing nothing and jump backward throwing kunais toward his brother to slow him down. But the kunais hit each other mid air and changed their trajectory making no one touch Dan but cutting off any escape for what comes next.
"Fire style : Great Fire ball jutsu"
"Wind style : Great Breakthrough"
Kyo quickly made hand signs to release a big ball of fire followed by a great gust of wind to enhance the power of his fireball because as expected his brother made an unknown jutsu forming a great wall of earth but with the increase in power of the wind the fireball totally destroyed the wall and made it's way toward his brother. Knowing it would not defeat his brother he ran just behind his fireball, sword in hand and slashed at the ground making his brother go out of his hiding and slash at his torso. As Kyo's sword made contact with the torso of his brother a huge cloud of smoke appeared and without turning himself Kyo slashed behind him blocking the strike of his brother as a log appeared in front of him. Kyo propeled himself forward with the strength of the hack of his brother.When he turned around he saw the eyes of his brother, now red with three black tomoe forming a circle, the sharingan.
2 years before his father, who unlocked it, explained to him what the sharingan was, what were it's effects and how to awaken it.
Back to the fight, seeing the strongest form of the sharingan on his brother shocked him and made him blanck out for second, unfortunatly it was enought for his brother to appear behind him and press a kunai on his throat.
Kyo's brother then let him go and laughed "Haha you have lost again Kyo !! But I have to admit you fought bloody well to force me to use my sharingan !"
But Kyo was too dumbstruck by what happened to answer him. As Kyo watched Dan with question filled eyes Dan just said " You are wondering about my sharingans ? As you know it has been more than a year since I had two tomoe, so it is not that surprising fot me to have evolved my sharingans. You need to know that even though you need to feel a strong emotion to awaken our eyes, to evolve it until the three tomoe stage you can just have emotions accumulating inside you."
Kyo pondered for a few second before saying" You just said 'until' three tomoe, does that mean it is not the ultimate state of the sharingan ?"Dan was surprised again by the cleverness of his little brother " Still as smart as ever I see, yes you guesses it write there is another stage which is the mangekyou sharingan, but I won't tell you how to awaken it. Just don't talk about it as it is a secret known by few as the only other person who know it is father, at least that is what I think as he is the one who told me."
