Today Me and Itachi visited the grave of Shisui, "Yuto, I want to give you something, it is something that Shisui left for you!" Itachi said to which I looked confused, "I will give it to you when the time is right" He said to which I nodded, before shisui died he taught me the advance shurikenjutsu and kunai throwing.
Later that day, I was training Sun breathing style, since I mastered Total Concentration: Constant, also since I don't have those special swords that demon slayer uses to kill demons, I have to do something like sasuke covering his sword with lightning, I also did physical training such as sit-ups, push-ups, squats and 8 km runs, all of those with weights attached to my body of course, my schedule consist of
-Breakfast
-Physical training
-Ninjutsu
-Lunch
-Chakra control exercise

-Genjutsu training
-Go to sleep
This is my schedule for everyday except for the weekend where my schedule changes to

-Go to the market with my mom
-Talking and playing with Sasuke
-Lunch
-Helping my mom with house works
-Training with Itachi and Shisui
-Dinner

I also unlocked my sharingan due to the death of our family pet ninja cat, who died of old age.
Next day
I was spending the whole day training when I felt that something bad is happening, (A/N: protagonist instinct) I quickly return to my clan compound by detaching the weights that were on my body, combined with body flicker and Total Concentration: Constant, my speed reached to that of high chunin.
When I reached the clan compound, it was too late, bodies and parts were everywhere and blood were flowing down the streets like streams, I quickly realized that today was the day of Uchiha Massacre, I run the fastest I can to my house, However I didn't noticed that my sharingan was turning from two tomoes to three!
Once I reached the house I saw Itachi was about to kill father and mother, I immediately throw kunai between them, which Itachi blocked with his sword but it brought me enough time to get between them, 'Hinokami kagura!' I yelled in my mind and slashed towards Itachi.
My reached Itachi but his body turned into crows, 'Crow clone?' I thought as I looked around me, Itachi then appeared about me with his katana aiming at me, I parry his strike as I opened my sharingan.
"Yuto please take care of yourself and Sasuke" Itachi said to which I replied "Why are you doing this?" To which he replied "This is for the greater good of the village".
Itachi then, disappeared and multiple Itachi appeared and surrounding me, 'Sun breathing first form: Dance' these words appeared in my mind as I slashed at the nearest Itachi, He just turn into crows, 'First form Flash dance!' I said in my mind as I used my speed to slashed all the Itachi's.
They all turned into crows, I then realized something, this is Genjutsu! I quickly dispelled the genjutsu but it was too late! I saw my father and my mother corpse lying lifelessly on the floor!
"Mom! Dad!"
