In the uchiha training grounds you can hear the sound of swords clashing,this is itachi and shisui along with a three year old izuraki sitting on a nearby rock soaking in the technique's they using with his hand? No his rinnegan, and he has his eyes covers by a bandanna which is black,why you may ask? because fugaku despised the bykugan so much he decided to seal them,he figured izuraki would be able to see because of the other eyes he has,he was right but he got reprimanded by Mikoto,so he played it off as 'training' anyway back to the spar.
Zebass:father there is someone watching.
Izuraki: I know, I suppose it's the hyuga trying to kidnap me.
Mikoto:itachi,izuraki dinner is ready!.Itachi and shisui stop mid combat kicking up dust
Itachi: we'll see you later shisui.
Shisui:yeah see you guy's later.
Itachi:let's go before mom gets mad izuraki. Izuraki nods and jumps off the rock and follows behind itachi,Mikoto seeing the two return walks back inside but before izuraki could reach the house he was knocked out by a chop to the neck izuraki could have dodged it but he was to caught up in his thoughts.
As itachi got into the house mikoto asked where izuraki was
Itachi:well he's right behind me. Itachi turns around to find izuraki is actually gone! Itachi quickly ran outside to look for him and what he saw shocked him,itachi saw him being carried away by two shinobi running to the tree line, itachi quickly runs after them and activated his sharingan he then takes out his tanto,and only mere seconds he reaches the two carrying izuraki and slash's down on them killing them and catching izuraki's unconscious body and taking him home.
One hour later izuraki woke up to find himself in his bed.
Sasuke:mom! Nii-San is awake!. Mikoto comes running into the room and hugs him tightly.
Mikoto:oh my baby,they tried to kidnap you those damn hyuga. Izuraki hug's Mikoto back and reply's
Izuraki:it's okay mom itachi nii-San saved me!.
Mikoto:yes but what would have happened if we did not notice you were gone. Izuraki does not reply.
Izuraki:well I would have killed them. Izuraki thought
Mikoto:come on let's go eat. The family get up and walk to the kitchen table and eat.
Izuraki:mom I'm going out for a bit I will be back.
Mikoto:alright don't be out to late I don't want you to get taking again, itachi go with him. The two walk out of the house before sasuke could come with them.
Izuraki: itachi nii-san I want you to train me.
Itachi:I'm not going to train you until you are six and in the academy.
Izuraki:but I don't wanna wait that long 'damn I have to learn jutsu from him'
Itachi:tell you what I'll show you one jutsu and I'll let you do light exercises.
Izuraki:okay!. The two then walk towards the training grounds in the uchiha compound after three minutes of walking they finally arrived.
Itachi:alright I'm going to teach how to do a fire ball our clans signature move. Izuraki activates his rinne sharingan which has only rings he has yet to unlock the nine tomoe, itachi is a little startled by it.
Itachi: do you know any abilities of that eye.
Izuraki: not yet I only know the name is rinne shringan. Itachi nods and decided to ask more about it later he then goes through a set of hand signs and spews out a big ball of fire.
Izuraki copy's the same sign's and spews out a even bigger fire ball but the flames were purple and was much more hotter,seeing this itachi,s eyes went wide itachi was then brought out of his stupor when he heard izuraki.
Izuraki:see that nii-San mine was purple!.
Itachi:y-yeah well I will have a training schedule for you tomorrow, let's go home.
Izuraki:okay!. The two then walk home with itachi holding izuraki so he doesn't get kidnapped again.
