ISEKAIED

In a new reality of another world as the boy puts his hand forward to unlock his magical abilities and what seems like a screen that is calculating numbers a burst of aura aminated from his body covering the hall with its might as if someone flooded the place full of water only to immediately be reabsorbed by the boy as he remembers what he was who he is and what he will be . 

"I feel like I've been sleeping for years only to find my self in this strange place that I seem to be familiar with. Every door , every corner I walked in and wandered around...yes this is the home I've know for 10 years."

Hey no,786 what was that ?! I get that you now of age and have magic but there is no need to show off … anyways what was his magical power level Sir?

… i .. ITs 1 000,000 he Hes rAnK iS A+ !
( that cant be he only just unlocked his magic . his only a commoner. they say his of unknown origin and was left here at birth) Enough everyone THIS MATTER WILL REMAIN HERE UNDERSUTDE!! YES MA,AM 

From then on I was the top of the class that year but my rank was set to C+ and I was praise by some and feared by my grade , as for the 2 teachers that where present they was more worried like this is some sign or something but we where clueless and payed little to know attention to it and as for me well I have over a 100 plans for this new life and know one will stop me from ruling this world  and living my best live and maybe get a few things I couldn't get in my old life that's right I'm taking all the women I like 

To my standards this school was not the best but also not the worst. In my past life I had the chance to go to both a private school and later a public school and I will say that its not as good as my private school but not as bad as the public school so in terms of place I'll have to say this is middle class at best 

"Normally students at the age of 10 start out at rank E to E+ capping between level 100 to 500 which is good for anyone ." In terms of power one with the right control and mastery over his/her magic at level 100 can destroy a house and at level 500 could even level a city, if they had the right spell ."
"That's the reason God sealed the powers of all races as we know , only a school is given the right to unlock a persons powers at the right age given they pass all the exams . Before awakening children where weak and had to eat as much food as possible without over eating in order to give energy to keep the seal from breaking which you may know but what we didn't tell you was that children that where eating less had less resistance to the seal so it effected them less so they where stronger (physicality) ,had less magic and had more potential in swordsmanship  which is why they have more energy to use but u on the other hand didn't show signs of having a lot of mana so you where given less then half the food u should have had  but somehow had the most magic . "So tell me what u have to say for yourself?" 

"Big sister what do I have to say to you I'm just happy to have such good talent "
"Good talent maybe but remember I'm only your big sis at home ." WE ARE AT SCHOOL! "
"Yes Ma,am."
"Call me Miss Carlly , also Rukito you will take the final test tomorrow as we dont want u destroying the school so best not over do it ok"
"Yes big si..s AH mean Miss Carlly eh     anyways gotta go see ya latter MY SWEET BIG SIS!"
(that boy never listens he always does what he feels is right but never speaks to others the way he speaks to me )

As I run back to my dorm someone familiar calls out to me. "Sayo-chan slow down don't jump!"
Sayori or as Rukito calls her Sayo-chan is his childhood friend and Carllys second cousin. shes still has 2 years to enter this school but stays with her cousin  "Big brother Ru-kun I hear u did something bad."
"Bad? huh I never do anything bad... OH YA they unlocked my magic and I'm at the top of the class and hares what happened..."
"So big brother Ru is not in trouble but surprised everyone by how strong are . Waah why was I not there to see I wish I wasn't 2 years younger than you could be as strong as you "
"Thats Ru-kun also you'll get there plus its not like school is this fun place to have fun as you would think"
"Don't act like you've been in school for years its only been 6 months  and other than having no friends u now top of your class so people will naturally want to befriend you also watch out for girls don't that to them when u have me!"
"Eh you scared they'll take me away hahahaha . Firstly I'll have all the girls I want secondly I know you my whole life how could I all for you when u the same cute child I still see u as plus you like a sister to me"
Sayo-chan ran away back home crying. Rukito returns to his room to practice controlling his mana for the first time

As I circulate my mana throughout my body following the same flow as my blood pumping through my veins I feel just how much power I hold inside of me . Its like feeling the pressure of the ocean but unlike it being outside is as if I can control the power of my ocean of mana inside me that feels bottomless with so many possibilities its endless of how much I can achieve .Lets try forming a ball of mana in my hand like an energy ball .... 

As he forms the energy ball in his hand things go well but as time passes the building and even the ground starts to shake but its much worse on his side . 
I something dark pushing out and as its pushing out my mana is gettiingng out of control and it feels like I'm about to explode . "uh..!?! " " I need to imagine sucking all the manna in a bottle and PUT A LID ON IT!" (sigh...)  as I begin to look at the mirror I see myself for the first time my eyes is somehow red? In the memory's of my new self my eyes was grayish purple yet it turn red but now that I look at it its going back to its original color 
A lot of people hear has more brown ,red ,orange and even pink hair yet I don't see any with black hair , even big sis has light blonde hair as for Sayo she has dark red hair that's close to being black .

After taking the test everything went quite well for Rukito spent 2 years in middle school skipping 3 years due to his talent in magic but also because of  how smart he was even teaching the teachers a thing or 2 .The last 3 years Rukito dedicated  it to his plan of reaching the top .

After failing in getting people interested in his new inventions that he used from his old world and his lack of knowledge in actually making the stuff himself he began studying magic .
There are the 4 elements that he learnt about in school at the time but they teach more only in high school so he begins mastering every element and after a year of  studying  he finally hits a break through discovering how to use his elements in a way know one has ever done before
by creating ice , plasma and electro he discovered a way to travel through space but this power doesn't  come from the 5 elements nor does it use mana but Rukito knows he needs to study this more than anything else and should keep it a secret  for now . As for the other stuff  writing a few magic books and selling it he made a fortune

 After a year of selling a million copy's of my book I have money the money to buy the hold city but of course I'm not gonna do that but now I got approved to market and sell global thanks to a big event merchants from all around the world will be coming in 2 days and big sisters farther uncle Grayfield is helping me and I get all the profit . Uncle Grayfield is the Duke of this dukedom so if it wasn't for him this wouldn't be possible but big sis came through for me 
Man I cant wait    

Eeehh (yawn) today is very quite I wander where everyone 
"Sayo-chan!" Big sis! "ANYONE!"
As I walk I feel something telling me not to go further but I open the door just to see a man holding Sayo by the neck as the man turns to meet my gaze as if he was waiting for me to come in.
"BIG BROTHER .... RUN!!!!!" (as she screams for Rukito to run the man holding her by her hair lets go as he slices her neck as if he was playing a game with the goal being getting a clean cut in mid air) 

The house as well as the city starts to shake as Rukitos mana is expanding rapidly out of control . Anyone below A rank would pass out be the amount of pressure that's in the air
Even the guy that killed Sayo stops laughing 

Rukito watches as the girl he grown up with a girl he loved dearly as family get murdered in front of him  everything hits as he was so ignorantly walking over his dead classmates to come here . The smell of blood never feel of as he was only worried about Sayori and now the only thing going though his mind at this very moment is

("!!!KILL KILL KILL KILL!!!" )
"!!!IF I DONT KILL YOU TODAY MY NAME WILL NOT BE RUKITO!!!"
