3 years later
It's has been three years since I reincarnated in this world and during these three years I learned a lot of things, I learned how to read and write in japanese, how to do chakra leaf exercise, walking on water and trees, the three basic academy jutsu and I also beginning training the breathing technique.
I didn't do physical exercise since I didn't want to injures my developing body but Itachi said I can do it when I reach age four, I also befriended characters like choji, shikamaru, ino, etc.
Today is the day where our father will test our chakra affinities and teach me and sasuke fire ball jutsu.
Yuto pov
Me, sasuke and father were in the uchiha training ground which has a lake, "Are you ready? Sasuke, Yuto?" said Fugaku, which we nodded, he then took out two white papers.
"Hold it in your hand and pour chakra into it" said Fugaku, we do as he said and Sasuke paper wrinkled and burned, while mine wrinkled, split in half and burned, Fugaku then said "Sasuke, your chakra affinity are lighting and fire, Yuto, your chakra affinity are lighting, wind and fire, but that doesn't mean you can't use other elements, the same goes to you too, Sasuke".
He then taught us the great fireball jutsu, which is the signature technique of Uchiha, we then came back home, ate dinner and slept.
The next day
Today I started training kunai and shurikenjutsu, while I was training, I sense two chakra signature approaching me, oh yeah I forgot to mention that I'm a sensor type ninja, I stop throwing shurikens and kunais, I then waited for them to reach me.
"Yuto, meet shisui, I asked him to teach you shurikenjutsu!" said Itachi introducing shisui to me, "It's nice to meet you, shisui san" I greeted shisui, "Likewise" Shisui greeted me, "Well then, I be leaving you two to practice" said Itachi as he shunshin away.
Shisui then taught me the basic shuriken and kunai throwing techniques, he also taught me wired shurikenjutsu, his specialty, since I haven't unlocked my sharingan yet, shisui taught me normal and easy wired traps and wired shurikens techniques.
After learning from shisui I partway with him and walked home, on the way home, I got hungry and since it's not dinner time yet, I went to eat ichiraku ramen, there I encountered naruto who was happily eating ramen.
I sat besides him and ordered a bowl of ramen, I was about to pay for my ramen when I heard naruto saying he forgot his wallet, I sat up and said "Teuchi san, let me pay for him" I pointed at naruto, naruto then looked surprised and started thanking me, he then asked to be friends with me, which I accepted.
