Chapter 1 : (ab) Normal Day

"AAAAH!"

One late night, Kuroko wake up because of a bad dream. He drenched in sweat from his head to his body, making his pillow wet. He lift up his blanket and get up from his bed. He go to the downstairs to get some water from his kitchen. When he arrive, he take a glass and fill it with some fresh water from his dispenser, then he drink it. After he put the glass to his glass shelf, his door bell suddenly ring many times continuously. The loud voice of the bell echoing in his house continuously.

'It's still late in night… Who is it?', Kuroko thought. His parents and grandmother is going on a vacation and will be back in a long time, so he think that it's impossible that his parents and grandmother have finished their vacation. The bell doesn't stop from ringing, so he started to be irritated. The bell is ringing on and on, making Kuroko feel that anyone in front of the door is trying to prank him. Angrily, he rushed to his main door, unlock the door, and open it hardly.

Kuroko almost surprised because in front of his house, there is no one there. There is only a small envelope in front of his door. He searched his field to examine if there is someone there, but Kuroko doesn't sense any presence around him. After stating that the condition is okay, Kuroko pick up the strange envelope and start examining it.

The front of the envelope seems okay, but the back of it is full of some signs of red liquid on it. 'Seems like some blood splatter…', Kuroko think. Then he examine the front of the envelope. There are some small letters written on it.

'To : Kuroko Tetsuya'

'From : Despair'

'To me? From Despair? Who is it?', Kuroko think. He doesn't know anyone named Despair or someone with a nickname like that. Kuroko decides to read the mail in his room. He close his front door, lock it, and walk towards his room in the upper floor. Then, he close his room's door and sit on his chair, and turn on his desk lamp. Slowly, he open the envelope and take a piece of paper inside it.

Before he read the content of the paper, he examine the paper first. The paper looks very dull, and it is a little dusty. But, the texture of the letter is really smooth, so Kuroko wonders what are the materials to make the paper. He examine the paper carefully. There are some sign of splattered blood, and a strange shape like 7Z7 in the middle of the back of the paper. Kuroko wondered about the sign, because he never seen it, but he decides to worry about it later. He can just search about the sign from the internet. Then, he flip the paper and read the content of the letter carefully.

To Kuroko Tetsuya

Good night, Kuroko. It seems are still alive and healthy. I'm happy to see your condition now, despite that your heart have been broken by this 'Generation of Miracles', right? I am still worried about you tough, so if anything happens, you can call me anytime and I'll help you to 'eliminate' your enemies.

'Eliminate? What the hell is this guy mean?', Kuroko think desperately. 'And moreover, how can he know about GoM and my relationship with them when we are still in Teikou?'. Kuroko decide to continue read the mail.

To the point, I'm sending this letter because there is something important that I should tell you. This mail involve your and your friends' life as well. From now on, there will be some strange events that you'll encounter. It might kill your friends or yourself, though.

Kuroko froze when he read the last phrase. 'Kill? Your friends? This is lie, right? It might be a joke, definitely…', Kuroko thought, not able to control his mind. His legs are shivering hardly, but he choose to keep calm as long as he can and continue to read the rest of the mail.

I am happy that you can have some peaceful moments with your friends before this incident happens, because this incident will bring a despair moments for you, and I bet you can't enjoy even a bit of the time you spend with your friends. I feel sorry for you, but this is fate that awaits for you.

With this mail, I inform you a terrible news. Your friends or yourself might be killed anytime, because they might be targeted by 'you'.

To be specific, this 'you' is your Impostor. This Impostor is a very dangerous being, and we can assume that he is a monster, not a real human. He just looked like human - like you, if I can say - with the personality like a monster. He will try to be like you, or more specific, to be 'yourself'. He will do anything to becomes 'you', like kills someone or doing dirty things. He will copy all of yourself so they can be his, like personality, aptitude, everything of you.

The point is, he will try to become 'you', take all you have, and kill you in the end to take your place in this world. Of course, he will kill anyone with no hesitates, as long as it needed to become 'you', even your family or your friends.

And beware, he can summon some terrifying monsters that can kill someone within a few seconds, but don't worry, the monsters is weak so you can kill them easily. The monsters exist only within a few minutes too, and your Impostor just can summon them once a day, so I think you don't have to worry so much of them if you have some weapons.

The only way to eliminate your Impostor is just to face him and kill him by yourself. And remember this, other people can't kill your Impostor. But beware, because if you meets your Impostor face by face, it mean that you must face it no matter what, because it will try to kill you as soon as possible. It's full of fatal risk because your Impostor surely has many deadly weapons.

Oh, and I'm sure that your Impostor will want to play with you first, so I think if you meet him, he won't attack you so fast. But stay aware as long as you can, because beside of the monsters, he can use other weapons too, so you can't rest yet after your Impostor unleash his attack.

And from today and now on, you will encounter your despair-filled life. And don't forget to ensure your friends' safety too.

Despair

"What.. What is this?! This can't be real!", Kuroko slowly shouted. His face has been paler than before after he read the letter. At the moment he think that the letter is a prank, he reads some small phrase in the bottom of the paper.

PS: Please consider that this mail is not a fictional thing. This is the fate you must face.

Kuroko surprised at the moment he read the phrase. It's just like the mail know what's on Kuroko's mind. Slowly, he put the mail in the envelope and put it in one of his drawer. Then, he quickly go to his bed and cover his body with blanket.

"This.. This is all a dream, right? Tomorrow, all things will come back to normal.. The letter will vanish, and I'll be back to my normal life..", said Kuroko. As soon as he say it, he sleeps on his bed.

The next day, Kuroko slowly wake up from his bed and sit on his chair. He is still sleepy because of the yesterday's night incident. Slowly, he opens his drawer to check for the letter. Does he found it?

Yes, of course he does.

Kuroko's face grown paler after seeing the letter. It still sealed nicely within the drawer. Kuroko quickly close his drawer and go to his bathroom.

'So it's not a dream.. What should I do?', Kuroko think, staring at his own reflection on the mirror. He sigh and close his eyes, washing his face with water. He really needs something or someone to entertain him now. He wipe his face with his towel and go to his room.

As soon as he reach his room, his phone ring. He reach his table, pick his phone and looks to the caller's name.

'Kagami-kun? It's so rare for him to call me this early in morning..'. Kuroko thought. Then, he answer the call as quick as possible.

"Ohayou, Kagami-kun. How can I help you?", Kuroko try to sound as calm as possible. He wants to hide his problems from his friends, especially Kagami and the GoMs.

"DON'T 'OHAYOU' ME! HAVEN'T YOU CHECKED YOUR CLOCK YET?!", Kagami shout from the distance. His voice is loud enough to make a swarm of birds fly, even it is from the phone.

Kuroko looked at his wall clock. It is still 09.05 o'clock in the morning. He wonders why Kagamii sounded so angry towards him.

"Ano, it's 09.05 o'clock. Why do you ask, Kagami-kun?"

"WHY?! DO YOU HAVE TO ASK WHY?! HAVE YOU FORGOTTEN YOUR PROMISE YESTERDAY?!"

Kuroko remembered, and he is trying to recall his conversation with Kagami in the previous day.

- FLASHBACK -

"Kagami-kun. Tomorrow is a holiday, right?", Kuroko ask, drinking his vanilla milkshake while walking towards his home with Kagami.

"Yes, why do you ask?"

"Do you want to have a practice match together tomorrow? I want you to teach me how to play a 'normal' basketball style."

Kagami stop walkimng after hearing Kuroko's words. He really wants to learn a 'normal' basketball style after defeating Rakuzan. 'Maybe because he already lost his misdirection..', he thought.

"Okay, if you want to do it...", Kagami said, rubbing his back of head. Kuroko smiled at him and it makes him blush.

"Arigatou, Kagami-kun. I really appreciate you if you come to our usual basketball court at 07.30 a.m tomorrow."

"What? Isn't that too early?"

"It's alright, Kagami-kun. I want to play basketball all day tomorrow, so it will be good if we start playing in the morning."

Kagami is a little confused, but actually, he accept it. "Okay then, if you insist."

Kuroko smile once again at him, and he walks at the opposite direction of Kagami's direction.

"Okay then, Kagami-kun. Let us meet tomorrow morning."

Kuroko turns and walks at his house's direction. But secretly, he has a plan in his mind..

-FLASHBACK END -

Kuroko now remember what should he do now. "I'm sorry, Kagami-kun. It seems that I have forgotten our promise. Moreover, I have just woken up a few minutes ago. It seems that I've overslept."

"IF YOU HAVE TIME TO APOLOGIZE, APOLOGIZE HERE NOW! I DON'T WANT TO BE TRAPPED WITH SOME STRANGE PEOPLE!"

"Once again, I'm sorry Kagami-kun. I'll try not to forget again in the other time. I'll go to the court as soon as possible. See you there.", Kuroko quickly answer Kagami's call and turn off the conversation with him.

"OI KURO-", he can still hear Kagami's shout before he turn off the call. He sighed slowly and quickly go downstairs. He go to his bathroom and take a shower quickly, then he eat his bread. He take his basketball shoes and a basketball, wear his socks and shoes, then go to his front door. He locked up his door, put his duplicate key under his carpet, and run to the basketball court.

I..I'm sorry! This is terribly short right? Right? Even the title has nonsense.. .

I'm terribly sorry for the bad grammar.. I'll do my best to improve it, too..

And please, no flames, I've done my best so far.. :(

I'll try to update this fanfiction as often as possible! :D

If you don't mind, R&R please? ^^
