The Son of Itachi

Prologue

(This story takes place after the forth great ninja war before the Boruto's generation was born but for the prologue its during Sasuke and Itachi's fight).
One year before

Shikachi's P.O.V.
Dad hasn't been home from this morning probably on another Akastski mission. Yes I know my dad is in the Akastki. By the way I'm six now my mom told me I got my sharingan at the age of 3 so I'm kinda better than my dad.
  Mom said dad has been sick lately, coughing up blood and what's not and he has tuberculosis or something like that. Anyway I was ready to train with my sharingan and shiruken.

Me/Shikachi: Mom I'm gonna go train.

Mom/Kasume':Okay sweetie, don't stay out to late and here's your lunch.

Me:Okay thanks, love you.

Mom:Love you back bye.

I waved bye and dashed off. Suddenly I saw huge dark clouds forming in the sky. So I hid my chakra and ran towards it. From a distance I watched with my sharingan as a huge dragon of lighting came down. Someone in a Akastki cloak dodged it, and used and orange Susano. Wait orange that dad's Susano and he's fighting uncle Sasuke. I observed as I saw Oruchimaru get sucked out of Sasuke and later get sealed. I watched as Sasuke quivered in fear for his eyes. Suddenly dad tapped his face and dropped down dead drawing a line of blood on Sasuke's face. I couldn't believe it my dad actually died. Hot tears flooded my face and eyes as Sasuke laid beside his dead body.
  I waited hours until Sasuke soon left. Suddenly I heard the voice of my father.

Dad/Itachi:Come out son I saw you the whole time.
I teleported to him and tried to heal him.

Dad:Stop son I'm gonna die,you can't help it.

Me:No dad I need you please.

Dad:Just do me one favour

Me:What I'll do anything

Dad:Forgive Sasuke
He said before dieing. I cried as my eyes began to change letting me see much more. It was my Mangyekyo sharingan I knew that it was. I teleported home and I told my mom what happened,she bursted into tears. I told her I was going to get revenge and that I was gonna start living in the Leaf,she told me not to but I did anyway. She have me my last kisses and goodbyes and I was on my way. I vanished to the front of the Leaf gates and I began to cry for my dad. Suddenly, a ninja found me and carried me to his place I drifted off to sleep not knowing who took me.
  I woke up to see the ninja standing there. I jumped up shocked.

Ninja:Sorry little one but I saw you last night crying and I had to help you. So where is your mom and dad?

Me:Dead(I half lied)

Ninja:Oh sorry about that you want to be my kid?

Me:Yeah okay but what is your name.

Ninja:Oh sorry my name is Shikamaru Nara and yours

Me:Um..Shikachi

Shikamaru:No last name?

Me:It's irrelevant

Shikamaru:What a drag guess you're a Nara then.

Me: Okay

My plan was working already.
