Academy

Kei did only one thing during her early years before entering Academy, training. Fugaku trained her and Itachi together and was quite strict about it. Both kids were very skilled, Itachi slightly more than Kei. It hurt her pride that a brat almost 30 years younger than her was more talented than her. So, she pushed herself harder than everyone. She started learning Fuinjutsu as it was the programming language of this world and would be very essential for her future endeavours.

Her Chakra reserves were quite large. Almost twice as large as Itachi with a large amount of Yin. She had to train extra hard to balance the Yin:Yang ratio. Sure, Uchiha's had inclination towards Yin but a balance would be ideal. She had successfully learnt Uchiha signature jutsu, Great Fireball Jutsu a.k.a. Distraction no Jutsu, Healing Mystical Palm due to her superb chakra control and got a good mastery over Shirukenjutsu, kunais and ninja wires over the course of two years. She also practiced using a sword

Mikoto tried many times to teach her history, how to handle tea ceremonies and other household chores, only to always getting rejected by Kei. Why would she learn such troublesome things. She would have to learn them in Academy anyway, and she didn't have any desire to graduate early from the Academy like Itachi. Good thing was that Mikoto was not as strict as Fugaku and let her do as she pleased. Truly, Mikoto was awesome!

Kei had secured her home with several seals. As she learnt Japanese more, fuinjutsu became much easier. Apparently, English also worked. The main point of Fuinjutsu was to know the process, have necessary input and having clear picture of what you want. Language didn't matter. Sure, if there were mistakes, it would cause explosion. Still, she didn't use English seals.

...

Now, she is 7 years old and sitting with Itachi among many children listening to a boring old geezer preaching something about Will of Fire bullshit. She is now entering Academy which didn't interest her in the slightest. Who wanted to go through the hellish place for a second time?

"-now please follow me to the classroom-"

A Chunin teacher's loud voice woke her up from her train of thoughts. Every kid followed the teachers into the classroom. She chose the last row in a corner.

"Itachi, where are you coming? Go sit somewhere else!"

Itachi slightly nodded and went to sit far away from her slightly sad. Kei sighed in relief. Her social life was limited to Mikoto, Fugaku, Itachi and boring noisy Elders. And Itachi bored her to death. Seriously, he sounded like a retired geezer in a child's body who had nothing to do, except thinking about meaning of life and whatnot. She was open minded and had seen many weirdos. And she didn't care what he thought. But he should keep his thoughts to himself. He would occasionally irritate her with questions like, 'Why do we fight? Isn't it pointless?', 'What is life?', 'What is death?', resulting in him getting his mouth sealed for hours.

She thought it was pointless to ponder about these things. Fighting is a nature's law and it is impossible to avoid fighting. Her previous world was a fine example. First, the stone aged people, then small civilisations, kingdom's, empires, eventually countries, fighting was always there. Even the modern age when most of the countries didn't decide to invade each other, economic wars, riots, etc. had not and will not subside. Even an organisation as small as a classroom wasn't without day to day fights. Everyone's goal differ. Who share same goals get along and who oppose fight. No need to care about something as simple as the cause of fighting.

...

"Kei Uchiha!"

"Present!"

"Izumi Uchiha!"

"Present!"

"Itachi Uchiha!"

"Present!"

"Hana Inuzuka!"

"Present!"

"Shina Aburame!"

"Present!"

"-------------"

Her class included Izumi, who was a noisy little girl who talked too much, therefore she avoided her. Hana, the Inuzuka clan heir, a Aburame girl, two Hyuga boys, one from Yamanaka clan and the rest civilians.

The first started and she only had one word to describe it, bullshit.

'They paint Hashirama as a benevolent man who didn't kill anyone in his life and wanted to be friends with everyone. Sure, he was a good man to end Sengoku period but they shouldn't change history to this extent. And Madara? He is painted as a cold-hearted monster with no feelings at all. He went rogue only when Tobirama was going to be chosen Second Hokage, who would bring the fall of Uchiha. Sure, he was a bad guy to take it out on his friend Hashirama, but atleast pay some decency to village's co-founder. The feats of Third Hokage is more ridiculous. He is as strong as Hashirama? Sure. He can create a forest out of nowhere. I wonder on what basis do they say it? He didn't participate in last two wars, let Senju and Uzumaki clan fall without doing anything, and is not even listening to pleas of Clan Head. No wonder most of the problems in Shinobi World pointed to Hiruzen and Danzo.'

The teacher spew some more bullshit and the taijutsu class started.

"Itachi Uchiha vs Kei Uchiha!"

Both raised their eyebrows at that.

'I will hold back and live in Itachi's shadow, I am already on radar of Danzo, Hiruzen and probably Obito.'

Itachi took his stance while Kei just stared at him in dissapointment. Why did he have to take everything seriously?

"BEGIN!"

Itachi ran towards her with his full speed and raised his fist. Itachi was not a taijutsu person. As soon as his fist was about to hit her, she grabbed it and and aimed for judo throw, in response Itachi tried to kick her but she simply left him midway and ran away from him. She expected him to balance himself but she could only shake her head in dissapointment. He fell outside the boundary by her unexpected move.

'This guy is hopeless without chakra and unpredictability.'

"Kei Uchiha wins!"

'Goodbye Itachi's shadow.'

...

"That was embarrassing Itachi."

Fugaku stared down at his son in dissapointment. He had been spying their first day at academy, like many other ninja parents. He knew that his son didn't have much talent in taijutsu as shirukenjutsu and ninjutsu. He did have a weakness to unpredictability. But the way he fell headfirst and lost in less than 2 seconds was something he didn't expect. Kei-chan's shock when he lost that easily further embarrased him. Kei-chan surpassed Itachi in everything with sheer willpower and never ending stamina in training, but the Elders will chew him out that his fiancée beat him that easily. When going all out, they were about equally matched if Kei didn't use seals, but it seamed like she utterly outclassed him in taijutsu without use of chakra. Well, kids learn from failures.

Itachi on the other hand, was planning to train his taijutsu more and was slightly jealous of Kei. He was a child afterall.

...

"""Hey! Why are you engaged with Itachi-sama!!? You b*tch!!"""

Kei was currently really annoyed. First, she had to attend some stupid class where she had to learn about some stupid flowers and teas. She simply used Sharingan to save it in her memory. Then, she was surrounded by noisy girls with some mental issues. They are what? SEVEN! Seriously, the crushes development started in atleast twice their age. No need to answer them. She just ignored them. They were just little kids afterall. She continued doing her homework without paying them any mind.

Then, one retarded girl decided that it was alright to snatch her notebook.

"Answer b*tch!"

'Woah! They are really intense. They are civilians without any training and not even able to sense chakra in them, but they really know to use such words.'

The notebook that the retarded girl was holding turned into several leaves and the notebook reappeared at it's previous place on her desk. Genjutsu. Blank onyx eyes stared into the girls' eyes to scare them. She would rather avoid daily. All of them ran away shrieking and crying. Problem solved.

...

Kei was currently in the Hokage Office with an expression clearly asking, 'why am I here?'. In the office, there stood Itachi, Fugaku and their homeroom teacher, whose name she clearly didn't remember. The Hokage were staring at them with an unimpressed expression. He started speaking, "So Hayato-sensei, what important matter did you wish to discuss with me that required Itachi-kun and Kei-chan's presence along with their guardian?"

"Hokage-sama, many parents complained about them. First for Kei-chan, several girls were crying yesterday and were scared because of her."

"And why do you think it is important enough to bring it up to me?"

Hayato tried to say something but his voice didn't come out. Someone has offered him *cough* bonus *cough* if he troubled the Uchiha's.

Hokage sighed and rubbed his temples. He wanted to finish his paperwork and head home. 'Let's just get over with it.'

"Kei-chan, did you do something that made them scared?"

"Other than not bothering to answer their question, 'Hey! Why are you engaged with Itachi-sama!! You b*tch!!' , not letting them take my notebook and staring at them like they are idiots, nothing else."

Hokage offered her a look of pity at her unimpressed stare at Hayato-sensei. He was just wasting his time with such puny matters.

"Hayato-sensei, deal with such matters yourself. It's your job. Now, what about Itachi-kun?"

"Some kids from upper class got into fight with him. Itachi defeated them, however, he was using a shadow clone and not attending the class."

Kei shot him a glare. It was only the second day and he got caught? This was what lead to early graduation in anime, and she would be dragged into it whether she likes it or not.

Hokage was surprised to hear that Itachi-kun was using Shadow Clone at such young age. He definitely knew that he and Kei were geniuses of their generation, if the boasts of Uchiha clansmen were anything to get by. Meaning, they were geniuses on par with Kakashi.

"Fine. Itachi-kun and Kei-chan, do you want to apply for early graduation?"

"No." Kei shot him down.

Fugaku and Hiruzen shared an expharated expression at the speed at which she shot down the offer.

"Both will apply for early graduation."

Fugaku answered. Kei shot him a glare while he simply decided to watch a bird out of the window. The bird was intriguing indeed.

"Hayato-sensei, test them after a week. Both of you good luck for your exam."

...

"Sorry Kei-chan!"

"Ara Ara~ Itachi-kun needs some punishment~"

Later that night, Itachi returned home completely drenched and covered in mud, with his mouth sealed till midnight and hands stuck on his stomach in a stupid pose. 'I am an Idiot' was written on his face with an ink that would not dissapear for atleast a week. Fugaku and Mikoto just sighed and continued eating their dinner.

"Hahaha!! Nii-chan looks stupid!" Even two year old Sasuke was laughing at him. That night, Itachi slept crying on his Mommy's lap. He just wanted to improve his taijutsu and decided to skip class. Why did Kei have to do this to him?

...

A week passed.

Kei and Itachi passed.

Record attendance of 2 days.

Kei was in a bad mood.

"Congra-"

Itachi's mouth was sealed again.

Mikoto praised Kei and offered her 1 month of free Dangos and Sushi.

"Please make a seal for Fugaku for me."

She didn't want to hear his boring Uchiha this and Uchiha that for a week again.

They shook hands sealing the deal.

Mikoto decided, Kei-chan is awesome!
