Author's note : It's not my first story, it's just first fanfic. It's not even first story I upload on internet, it's just first in English, and in FFNet. My first language isn't English and I started learning it properly pretty late, so you are welcome to correct me in grammar or spellings anytime. Another point is, I never played KH 1, KH 2, KH CoM.. I played 365 1/2 days, FF VII, and FF VIII. Some spoilers, or out of characters... ...I have no idea. So you can point out them to me, too. I'll see if I can change or fix it, as long as it doesn't disturb a lot in my plan.

Diclaimer- None of the characters or most of concepts are mine, they belong to Square Enix. Honestly, if they belonged to me.. ..It would have turned MA+ rated.

Warning - Yaoi, M rated for more than a few reasons (later chapters), abusive languages, crimes, etc. Yaoi pairings (AkuRoku, SephCloud, ZexionXDemyx, etc, more side pairing though not in this one. Side stories may be included after the main story gets over)

No. XIII - Organisation XIII

[Prologue]

[In the middle of darkness and light, the shadows of both lay.

The shadows, the midst of the extremes-

They lurk in the most unexpected places at the most unexpected times,

And they reign with the mystery and power,

The shadows call themselves-

Organisation XIII.]

The dark underground hall was silent, though it was filled with everyone who was supposed to be there. Glimpses of the hooded figures were shown by the rays of light penetrating the wall of darkness. It was indeed a strange place, where both darkness and light co-existed, confusing anyone who would try to find a word to describe the place. All of sudden, the one, who sat on the highest sit, spoke, breaking the silence of the place.

"...So this is the end of the monthly meeting. All issues were discussed.. Now, I have to warn everyone about tightening police investigations and rising interests on our small organisation.. I believe all members are capable of hiding their own identities, but still, more securities and safety measures would be required. ...No. VII?"

"Understood, No. I. I will be more careful in handing over missions to our members from now on."

Another hooded figure answered, as emotionless as the first one. The one who was referred as No. I simply nodded and continued, changing his cold voice. A sudden change- his voice now dyed with slight excitement and amusement.

"Then all issues are clear.. Now, I want to declare that I finally found a material who is capable to be one of us, a member of Organisation XIII- Someone who is capable to be our last, and final member. Welcome our final master piece.. No. XIII."

The doors slided open without any sound. Another hooded figure glided in, gracefully and almost ghostly. The figure was small, and had hood kept down to his nose. None of them would be able to see his face even if anyone went close to him. As every hooded figure looked down at him, curious- The hooded figure simply stood in the midst of them, not moving an inch. When all hooded figures turned motionless again, No. I spoke in a voice still excited.

"No. XIII's main missions shall be erasing the traitors and any who goes against our wishes. For No. XIII's targets may also include our own members- No. XIII shall remain unknown even to us. No. XIII won't speak, nor show face, nor share name. No. XIII will be present in our monthly meetings, but will remain silent. No. XIII, I believe you are aware of your responsibilities?"

"..."

No. XIII nodded, standing still. Others stared at No. XIII, disturbed, but he remained silent, looking rather ignorant. No. II, however, questioned No. I.

"...How old is No. XIII? No. XIII looks rather too small to be one of us. Are you sure that that kid can be one of us, Xemnas?"

"...Xigbar. No. XIII is capable.. And No. XIII is aware of his works, well enough. If you doubt that No. XIII can't challenge one of us- You are mistaken. No. XIII is a genious in battle. I believe is good enough. I do not deny that No. XIII is younger than any of us, but I'd like to entrust him with the Organisation XIII if anything happens to me or the Organisation crashes down by any chance."

"What!"

"Xemnas!"

A few hooded figures sprang up, shocked. Some of the others who remained seated also either looked up at Xemnas or looked down at No. XIII who seemed to remain ignorant to everything. Most of them where shaken, especially No. VII and No. VI.

"Xemnas! What are you talking about! If anything happens to you, or the Organisation crashes down! That will never happen!"

"Who are you entrusting us with, No. I? I thought I'd be the one who was supposed to be in Saix's position when anything happens to you, and Saix covering up your position!"

Murmurs in agreement. Though some remined in complete silence, Xemnas turned his head to No. VII, Saix, and No. VI, Zexion, who still remained standing and stared at him.

"...Saix, and Zexion... Calm down. I was saying if anything happens, and if anything does happens to me, it will be likely to happen to Saix as well. And Zexion, I believe you have understood what I meant by. And even not so! I am the leader and my decision is final. This is for the good of the organisation. This is an order."

Silent reigned the hall. Soon, one by one, the members turned back to their motionless original postures. Xemnas gave a nod to No. XIII who remained in silence. No. XIII sat down on the last empty chair, and the chair slowly rose up, keeping No. XIII high up with others, but at the lowest position, for he was the last member of the organisation.

== 2 months later... ==

"Marluxia, but this is-"

"Don't you wanna stop this? I know that you hate to stay here, Axel. Don't you wanna put an end on this?"

"I do admit that I am getting tired of this stuff, but what about the others? Xemnas, Saix and a few of them are obsessed with the Organisation XIII, but what about the rest?"

"I am putting an end to everything, Axel. I didn't think of going as far as this, but the existance of the No. XIII disturbs me. Whoever he is, I don't care, but his works, his roles, what he had done in mere two months - I can't believe what Xemnas said, that he is younger than us. We are in university now, aren't we? That means No. XIII is at the most a high school youngster. And think of it, a high school student! Axel- What kind of high school student is No. XIII? He or she or whatever he is, just remember what had happened for past two months, any who defied Organisation XIII's rules, any who questioned the Organisation's power or intentions!"

"..."

Axel remainded mute. It was true, what Marluxia said was in most of the members' minds. Axel had seen those dead corpses.. Clean cuts, the wounds evidently made by someone who had no hesitation of doing such acts. Murdered brutally and left rotting for weeks at the trash dumping site.. It was clearly not a work of a normal person. Whoever had done that must be crazy. Finally, after a few more minutes of Marluxia's pleadings, Axel agreed to help Marluxia. However, they didn't realise Zexion who was standing outside of their room, who also decided to remain silent, though he may not help them.


"Raise your hands! We will shoo-"

*Gun shots, shouts*

"Everyone, evacuate! Now!"

Xemnas shouted, keeping his head cool. Xemnas could see other members still in confusion and chaos- Zexion, grabbing Demyx and rushing out from the hall, Marluxia and Axel exiting from another exit, Saix and Lexaeus who happen to be together suceeding to escape before the police force actually gather to get them- And there was Xaldin and Xigbar beside him, who were helping him causing distractions. Xemnas also saw Vexen, Luxord, and Larxene being caught by the police. But they didn't have time to rescure those three- Cursing under his breath, Xemnas led Xigbar and Xaldin out of the hall, and to the secret hideout where they could hide for the time. He knew that the police had saw him, Xaldin and Xigbar's faces. The police would search for them now.

What else could he do? Xemnas realised that he lost his handphone. It must had fallen while he was escaping the hall. There was no way he could go and claim his handphone again. Xemnas cursed aloud again when another thought hit him at the moment he was about to call No. XIII by the telephone.

"..Damn it! I can't call him! And now he won't be able to contact me, with my handphone lost..!"

"...! Xemnas?"

"Calm down, what's wrong! We still can rescue others and meet the members who escaped-"

"We can't do anything, we simply can't! Accursed traitor, who can it be! The police couldn't find our meeting hall unless one of the members helped them! Three of our members are caught- Then now I can't call No. XIII! He won't realise what is going on- He won't even know that he is related to us! I can't just call him like this!"

"Xemnas?"

"Wha- what? No. XIII doesn't even know that he is one of us? How can that be!"

Xemnas threw the phone to the wall, breaking it into pieces. Xigbar and Xaldin tried to calm Xemnas down. After sometime, when Xemnas finally calmed down- he sighed and explained to Xigbar and Xaldin who demanded an explanation.

"..No. XIII... He has double personality disorder. To put it simply, No. XIII who joined our Organisation XIII was not his original personality- Somehow, his other side- darker side has stronger influence on himself. No one else knows that he has this problem, not even himself. I happened to talk to 'him', who was temporarily out at the time- and from that time, he started to talk to me more and more often.. And I started to think that he was a perfect one to fill up the last position in the Organisation XIII. I gave him my phone number, and I told him that I will give him a weekly call, though I always saw him in the college where I work.

It wasn't only because of the missions, but also because that No. XIII himself never realised that he had joined the Organisation XIII- That was why I was forced to keep everything of him away from the rest of the members. That makes him the best member to escape the police investigations and other possible suspiciousness, but now- I lost connection with him. He won't be able to contact me either, and he won't reveal himself to any of the other members unless he is perfectly sure that he can believe that member.. Which I highly doubt that it will ever happen. Now.. We have no choice but to hide till the police has loosen its search."
