"Fuah ,yesterday was indeed good harvest."(Alya)

The beam cannon part yesterday..even though some of them are trash,the rest of it was good and cost A lot of money maybe around 2 houses or 3 houses?well who cares,i just couldn't stop smiling...what a lucky guy i was...though part of thanks to nee-san who allow me to do as i wishes..if nee-san didn't come then it would be taken by a police whic a waste because it would only be put in police evidence area.now now,i just need to wait for material that i ordered yesterday and i could start with it..

until it arrive let's enchance the Blade pack further..the shoulder part was still normal armor...hmm maybe i should add some booster to make it more balanced?And beam knife i would put 3 more the whip...holding with a hand was a pain i should put in my hands like anchor.Now now i had many things to do....The empty zodiac without weapon except arm and standard booster beside me was ...so empty...it was lucky they were only ant.for now i should upgrade it.

As i upgrading it,There was someone coming,well must be nee-san.Let's ignore it.

hmm for the beam knife..maybe i should put in waist guard and fuse it with blade pack?yesterday it was kinda lack in defense with made barrier consuming faster...the waist guard...immediately i go to storage and pick the waist guard i didn't plan to use and put it in fuse it with pack,i also pick some shoulder guard and do the same like waistguard....if it was shoulder guard then booster wouldn't be needed.now beam saber ..let's add 3 to each shoulder guard.........well it just finishing and put some parts today i must finished it...

8 hours later......

Finally Finished........as i smile with satisfaction my blade pack...2 shoulder guard with 6 beam saber and barrier generator,waist guard as beam knife holder and auto rifle,whip that put on hands to bind enemies,Dragon fang sword which was made of certain beast fang which could be used as defend through beam and become giant beam blade...this should be good enough for now.Immediately i turned around and saw minamisit on chair with surprised face.

"Never expect you could smile that.."(Minami)

"Since when you was here?"(Alya)

"Since beggining you upgrading the pack.for note,the school was taking a break for 2 whole days ,Azure Phoenix also put in repair by my family,so the only thing left to do was going here..."(Minami)

Oh it wasn't nee-san but it was her instead,that's why nee-san didnt' ask me anything or give me suggestion...wait...How the hell she get here?

"...How the hell you get here?"(Alya)

I was sure the security system would be able to stop you,beside there was nee-san at home there was no way she let stranger in .

"By your nee-san,Once i said that i would persuade you to go to school she immediately let me in with smile.even thanks me for helping her."(Minami)

...................So instead nee-san who nagging me,now it would be her instead?I never expect this...so it was her plan along...that fox!!

"Go home,Don't bother me working ."(Alya)

I said that and turned around once again,after that i do an O.S maintenance and little optimization at Hydra O.S with my laptop.There was some slight reaction error and the output was 1% lower than initial plan.as i working on it minami ,who was sit on chair behind me ,ask me.

"Alya,just who are you?"(Minami)

I continued doing what i do, as sign i didn't want to answer her.

"Your killing intent was abnormal,what's more you didn't had any hesitation when you killed which was impossible for 16 years old.."(Minami)

I just answer with silent.

"Your technique was like 12 Ace of Earth special force,the knighof of round .no it was more than that,your mechanic skill was also not everyone couldn't learn."(Minami)

Once again,i only answer her with silent.

"This was just my thinking and maybe it was wrong.but i would try anyway."(Minami)

hoo,my identify before war huh..

"The legendary Ace of humanity that vanish from front line 3 years ago,Code name..Arthur pendragon"(Minami)

I stopped typing....and put stop the maintance for a while..well she was right,i immediately turned around.

"What did you want?"(Alya)

"I want to ask you 3 questions."(Minami)

Typical...i give her gesture to go on.

"First Arthur pendragon zodiac was Mirage dragon,was it the zodiac you upgrading now ?"(Minami)

"No,this was zodiac that i created by myself and also Zodiac mirage dragon were destroyed 3 years ago."(Alya)

though it was me the one who destroyed it so the military won't get it.but i still had the O.S with me,hidding somewhere in this house.

"Second,how old are you?"(Minami)

"16..this was the truth,if you didn't believe me ask nee-san."(Alya)

for the achievement that i had done ,they let me and nee-san to retire from front line or more likely it was us who force our way,of course as a member of knight of round table they didn't want me more to go..but i give them some "present" so they will "Retire too" and they let me go without struggle.thought the present was for the one who did the corruption.

"Last question,Why you retired from front line?"(Minami)

".....You didn't need to know."(Alya)

A stranger didn't need to know that.well before she told everyone maybe i should threat her right now.i took out my electric gun and point on her.Then immediately my gun was taken ...by nee-san.

"....Stop it ,there was no need for you to threat her."(Ceria)

"Why?"(Alya)

She sighed then put my gun on the table then while she folded my arms she told me.

"Alya..you were not soldier anymore you were just a student now so pleace act like one."(Ceria)

.....i didn't answer her,then continouing maintenance the O.S and optimization

"Nee-san were you an idiot? why did you tell her?"(Alya)

"Just how long were you gonna act like that?You weren't arthur pendragon anymore there was no need for you to act so alert like that,beside it was a good chance you to make some friend.Beside Minami was sincere girl surely it was a good choice."(Ceria)

"I don't interested in making friends with others,they would only be a pain."(Alya)

As i continued do O.S maintance and optimization,and want to ignore her.

"Then why you retired,if all day you were just do a zodiac maintance or training.Didn't you retired because you were hate living like that?"(Ceria)

I stop typing then close my laptop.

"I was just fulfill my promise to 'her'..that's all."(Alya)

Immediately i put away my zodiac from their touch then i went to my room and continouing my O.S there.

Narrator POV.

"Sigh,what a trouble some guy,well minami do you think you still could berfriend him?."(Ceria)

"....Nee-san...what he did mean by her?"(Minami)

She scratch her head,while sighing lightly then she tell her.

"Her code name:Modred...just to make sure,did you know Modred betrayal right?"(Ceria)

"Yes,using legendary zodiac Hurricane zephyr she destroy 3 towns.single handedly by herself."(Minami)

That was the worst accident in history to think a knigh of round the hope of humanity betray the humanity itself.forever in the history modred names would be branded as criminal...

"She was Alya childhood's friend."(Ceria)

Minami was shocked...because the news say ...the one who killed modred... Arthur pendragon...It was alya.Alya the one who killed himself.

"I didn't know what happen,because i wasn't knight of round.but surely it was life and death battle because Zodiac mirage dragon was destroyed..."(Ceria)

"Then the zodiac from before..was it was really self-created?"(Minami)

Minami at first though it was a joke...but to though he was this kind of genius..

"Not just the zodiac,The O.S too."(Ceria)

..........Just how insane was that?To create a O.S that could par with legendary O.S ,for human it was impossible!!!Legendary O.S was things from before the great war with Zoonic beast. and was created by mysterious person.no one could copy it and everything was insane ,not to mention there was special ability in which O.S,A self-created O.S...just what was he?

"Back to topic,The reason he dessert the Earth special force was because of that and his promise with her that no one knew.well good luck for persuading him to go to school."(Ceria)

Ceria waved her hands then only left minami alone..

Just what was happening in the past?

Alya POV

2 hours later,

as i was pick up some cereal from refrigrator,Minami come to me...why she didn't go home yet?

"Alya,please go to school...i know you were wounded because you lost your childhood friend...but that's why you must kept living for her.."(Minami)

"What you should care?Just care you own problems and don't bother me."(Alya)

There was no way i could told her...Modred was still alive...or that's what she was promised me.That's why to fulfill that promise i will keep living..the reason i retired was because the risk of death in frontline and would be dangerous for her anyway.This was only promised between us...and i only living because this after i lost all of my revenge for my mother.

"I challenge to 1 1 duel!!IF i lost i won't bother you again,if i win you will go to school!"(Minami)

"no,it was a pain...beside you couldn't do anything here anyway."(Alya)

I started eating cereal while doing an optimization on the O.S.until she forcely closed it...oh well it was fine.

"It wasn't polite to ignoring a friend's talking."(Minami)

ignore her,i eat the cereal ,after that i prepared to go my room but she hold my laptop.

"Release it!!"(Alya)

"No!!!Until you go to school!"(Minami)

using my free hand i took out tranquilizer gun and want to shot her.but nee-san get in the way again.

"Just how many times i told you,no weapoon use at home."(Ceria)

and just how many times did you want to repeat this action?

"....JUst give up and went to school would you?Considering you were lacking material to finish orther packs anyway."(Ceria)

....so she knews huh,

"I would pay you...for going to school each month.."(Minami)

as expected of Her..considered she were very rich..

"There was no need for you to pay him minami,How about this alya...i would give you more money so you could buy more parts but...you must go to school and berfriend with Minami at least..."(Ceria)

.....A pain...

"No.."(Alya)

"Considering i had information about other legendary O.S?"*(Ceria)

What?how did she get into that?

"How was it would you be interested?"(Ceria)

....considering it could upgrade Hydra O.S more further..,well i kinda lacking data in long range and speed anyway..even Short range only average..

"Fine,i would accept it..there was no other option anyway."(Alya)

No other option for upgrading the O.S.beside 80% of the zodiac already finished anyway...just need the O.S and it would be complete.
