the white haired Uchiha

My name is Kagami Uchiha I'm the twin brother of Sasuke Uchiha with one slight difference in appearance my white hair but besides you'll see the rest alongside my journey enjoy

age 10

Kagami: ever since I came into this world. members of the Uchiha clan dislike me because of my different hair which for a Uchiha is normally black but mine is white which I have a theory is because I have a strong yang release not to say my yin is bad but it's not nearly as strong so my body is stronger than any Uchiha my age because of this difference I have noticed that too but it's a stupid reason to dislike someone for having white hair

As you readers can tell Kagami is a reincarnation of a person from our world so he knows this world very well from his past life. 

Kagami: I'm currently Genin level with ninjutsu since I'm limited on what I can learn due to my age and rank but my chakra reserves are amazing for my age being at high-chunin on the brink of jonin level due to abnormality of yang release but in taijutsu I'm well above any have my classmates being high-Genin in taijutsu and my affinities are Lightning being the strongest and water release being right behind and fire being the weakest so let's say I'm an oddball to the Uchiha but as my entire family say I'm a breath of fresh air to the clan being unique 

Kagami senses someone approaching the training ground he's in and the one being his eldest brother Itachi and his mother his 2 favorites out of his family no offense to Sasuke and Fugaku but he loves all of them,

Sasuke and Fugaku have a pole up their butts but anyways he's body flickers to them

Kagami: hello Mom and hello brother 

Mikoto: I thought I should bring you food since you are out here training 

Itachi: and I'm here to give you this and he hands Kagami a scroll 

Kagami opens the scroll and sees the lightning-style training method 

Kagami: Thank you Itachi and thank you Mom 

Itachi: no problem I got that because you seemed bored because for your current body, you can't push the Uchiha taijutsu anymore and your ninjutsu was limited to the academy ninjutsu, great fireball jutsu, the body flicker and shadow clones so with this you'll be able to push your ninjutsu once your lightning affinity is mastered and considering you are a genius like me I have no doubt you will create new lightning release jutsu and hopefully soon I'll be able to get my hands on the water release training method too 

Mikoto: but here's your food My little snowstorm

Kagami thinks: I always like that Nickname considering I didn't have one in my past life.

Kagami: thank you Mom

Kagami scarfs the food down in 5 minutes 

Kagami: now that I'm done you are more than welcome to watch my training 

Kagami forms 3 shadow clones and has each one work on the new lightning release training while he works on his taijutsu 

Kagami thinks: the next 2 years are crucial for my training because after that there will be absolute chaos the only upside is the Uchiha clan wasn't massacred for some reason but I'm certainly not complaining
