Over the next week , kirito continued to come to the pond to practice after academy,
He repeatedly rejected his friends invitation to go with them after school.
After one week of continuous practice he was now able to run on water easily after that
the next weekend he went to a river which has high speed running water currents.
After more two days of practice he was now again training in Shadow clone jutsu.
And he could now make a shadow clone which is almost perfect copy of his .but he wanted a clone which no one could ever differentiate between.
As he continued to attend academy
Where they were only given lectures untill half a year..
He was bored of this , they were taught the will of fire before anything else so that they will be brainwashed early .
And thank the village for everything they have .
After a month of practice he could now maintain a clone and it was exactly 100 percent his copy.
Now he could send his clone to academy and he himself could practice daily in the forest .
So from next day he sent his clone to the academy and he himself went to the forest
while always under the cover of transformation jutsu which he had mastered to a terrifying degree .
No one in the academy could pin point that the kirito who was attending the class was a clone not even the teachers.
In the forest kirito was now preparing to learn the concealment jutsu which he had memorized from the scroll .
As he was training how to conceal himself like the anbu , he was able to learn it easily due to his high chakra control level .And he discovered that he could conceal himself completely .he didn't thought of this first .he thought it was normal .but it amazed him when he was able to conceal himself from a random SHINOBI when he was going back to his apartment after training in the forest .After all he was a academy student but the SHINOBI was a high level seasoned SHINOBI because he could see his jacket he was wearing.
After some thought he could only think of it as a bonus during his reincarnation .
So he spend a whole month on mastering the chakra concealment jutsu.he further went and tried to conceal any sound he produced during movement.
He would apply the chakra to his feets to reduce the friction to not make any sound during walking .
He also discovered he could also conceal his true chakra level from others and dicided to conceal 75 percent of his chakra .and only show remaining part as his chakra amount to others .
His chakra amounts were high due to his high spiritual energy and good physical condition due to repeated exercise he was doing for almost a year .
After learning the concealment jutsu he could now move in and out of the forest now without relying on his transformation jutsu.
He also went to a weapon shop and due to the master level concealment jutsu he took some kunai , shuriken , explosion tags and some training swords and a fine sword .
He also took some storage scrolls for storing these weapons ..
After leaving the shop he went back to the forest for training.
He also received the memories of his clone at night daily about the academy and his clone also went with his friends to play now after leaving the academy.
He also found there was a commision after the shop keeper realised his missing weapons and a team of SHINOBI were given the mission to found the culprit.but they couldn't find as he had not left any traces there and due to his over cautious attitude he didn't went to the forest to train for 2 weeks because he didn't want to be caught.
Even though he knew he didn't left any traces .
After some time when the commision had died did he went back to his training and started shuriken trowing techniques and kunai trowing techniques.
He also started his anbu style swordsmanship training which he had found in the scrolls .
He continued the training for half a year .
After nine months of continuous brainwashing lectures in the academy did they started to teach other things ,but they were only taught physical exercises as there class was a civilian class there were many who hadn't awakened or learned to mold there chakra , So like this the first year in the academy came to an end .the students who couldn't mold there chakra after the end of year were expelled from the academy as they were not fit to be SHINOBI.
His maximum class students were expelled as every one didn't have the talent to become a SHINOBI ,his friends were also among them .
During this year he also learned sensory jutsu which had a range of 500 metre in all directions and a range of 2 km if he only senses in one particular direction.
which was a great for a sensory SHINOBI.
Like his concealment jutsu he found talent in sensory jutsu also.
But his vision was not that great .he couldn't keep up with his body movements with his eyes .
So he started to rely on his sensory jutsu during fast movements .
And also started to try to improve his vision by injecting chakra into his optical nerve .
for fast cordination of his C.N.S and body .
He was also thinking of injecting chakra into his eye lenses and retina for developing dynamic vision .
But refrained from this untill he was confident enough not to injure his eyes .
He also continuously practiced chakra control training.
He also practiced to produce chakra thread and move it with a thought like it was his.
limb
His chakra control increased due to this .
He was practicing to sharpen his chakra threads and make skills like doflamingo made with his string string fruit .
During the second academy year they started to learn shuriken trowing techniques and some taijutsu styles which was basic .
He also came to know about the prodigy who was found using shadow clone in the academy and was graduated early at the age of 7 .
His name was Itachi Uchiha
He kept his distance from this prodigy during the whole time in academy and he wasn't the only one ,many were doing the same due the rumors that were spreaded through the whole village that the Uchihas were responsible for kyuba attack .
Kirito didn't care about these rumors as he only thought of growing stronger .
During his academy second year he and other students in his classes were transferred to another class as many students were expelled after failing to mold chakra .
He could also make 4 shadow clones now
which helped him him during training.
He assigned different tasks to the four clones ,
As he didn't had to sent his clone to play with his friends now as they were expelled and he didn't made any new friends in the class .He also had little presence in the class like shino .
So nobody ever felt anything wrong with him
One clone was assigned for weapon training.
second to sensory jutsu,concealment jutsu and chakra control and thread techniques,
third to learn the chakra nature transformation and chakra shape transformation techniques (he checked his elemental affinity and found he has chakra affinity for all elements)
Last clone to learn the legendary jutsu of fourth Hokage rasengan .
And he himself went for taijutsu training which his clones couldn't help him with .
In the third academic year he continued his
training.
During the fourth year he started to learn the elemental jutsus he had in the scrolls
His chakra continued to increase and his taijutsu also became good enough .
During the academy years he always kept his performance normal .no showing off ,he was in the middle of class ranking.
During the physical training and spares he always held back but showed like gave his all. No one could think he was acting as his idol was the third hokage himself.
