2 years ago...
The black hair boy was sleeping soundly on the ground. Although he craved for sleeping, the boy couldn't escape from his unending nightmare.
- I think he is here. - A voice from distance said. Although it could hardly been heard, the boy somewhat felt uncomfortable. His eyes began to move as if the nightmare had gone worse.
- Search in here. Find the boy. - that voice became much clearer.
- No... - the boy's body began shaking.
- CATCH HIM! - This time, the voice came too close not to recognize.
His eyes opened widely. In front him was a man about his fifty.
The old man smiled to him. His smile was disgusting... very disgusting...
- Haine-kun... I finally catch you.
The next thing he knew was all black. The man smirked widely. He was like a mad man.
RING! His phone rang.
- Hello, who are you? - the man said annoyingly.
- Shitori, how are things going? Have you caught him yet?
- Oh... Boss... I... I managed to catch him. Haine Ren!

-
In Tokyo...
- Well, this place is so big and modern. - A young boy around his sixteen gasped in disbelief. Len was looking around the platform. This was his first to in such a big cities.
Ring...ring... His phone began to ring.
- Hello?
- LEN-KUN! HAVE YOU BEEN THERE YET?
A loud voice spoke through the phone.
- Miku-chan. You don't need to ring me that often. You've just rung two minutes ago.
- Sorry. I couldn't stop worrying for you. So have you seen your school yet? - Miku asked excitedly.
- Not yet. I've just been here.
- Okay... I won't say anything anymore. But you must inform me of your latest news...about your school, the students...the teacher, too! It's boring without you here.
- OK! - Len smiled halfheartedly.
- Yeah.
As he was talking to his friend on the phone, Len suddenly bumped into someone.
- Sorry. I wasn't paying any attention. - Len apologized.
- Ah... It's nothing, really. - the man said. Len looked at him. He was a handsome man about his age, but a lot taller. His hair was quite weird. It was purple and very long.
The man looked at Len for a few minutes and asked:
- I guess you must be new here.
- Yeah... - Len said embarrassingly. - I have just gone here from Osaka.
- Oh? You looked like a highschooler. May I asked who are you?
- Well, my name is Kagamine Len. I'm waiting here because my school tell me that there will be someone here to help me with this city... That's all...
The man smirked.
- Does the school tell who will guide you?
- Um... - Len thought for a moment. - If I'm not wrong... he is...
- Kamui Gakupo? - the strange man asked. Len looked at the man in front of him. He was so tall, that Len couldn't believe that he was in the same grade.
- You...you are...
- Yes, the one who will guide you in this city.

Somewhere outside the street...
- Oh? Hey, little cutie. Do you want to have some fun tonight? - A bunch of teenagers asked a girl in front of them. This girl had blond long hair and blue eyes.
- Eh? - that person asked them. - What kind of fun?
The teenagers smiled widely.
- You know, some sorts of thing. - One of them came closer and touched the girl's hair.
- I know you will like it...
SLASH...
The blond girl slashed the man in front of her. His blood was dripping. All the others looked at her frighteningly.
She leaked the knife.
- Blood sure are good, nee?
- AHHHH - all of them ran for their lives.
- So boring, I thought I would have some fun. - The girl smirked.
- Don't get too much attention, Kagamine. - Some one from the shadow talked.
The girl reverted her attention to that person.
- IA-chan... This city is soooo boring... - the person stepped out of the shadow. She was a beautiful girl with silver hair.

After one hour exploring the city...
- So what do you think about this city? - Gakupo asked Len.
- Um... it's very fine... I think I'll love to live here... - Len answered. - What else do I need to know?
- Nothing much... Recently, there's a dangerous yakuza organization called Yami. Do you know about it?
- Yami...? No, not much. I heard it somewhere.
- Well, you don't have to worry, the police will catch them soon no matter what.
- Eh? How do you know? -Len was curious.
- My best friend is kinda...um... involve in these stuff. I'll introduce you to him tomorrow. He'll come to our class too.
- That's great. See ya!

The next day...
- Welcome to our class... - the head teacher said something.
Len was tired because of the traffic this morning. He was so anxious that he didn't get much sleep last night either.
He hoped that the first day would be fine, and he wouldn't stand out to much... a peaceful school life was what he wished for. Continuing for about two or three minutes, he yawned.
- OK, students. I have given you the permanent seats this semester. Now, please head to your new seat. - The teacher commanded.
Everyone settled down.
- OK, let's go to the introduction part. You, yes the one with blond hair. - The teacher pointed at Len.
- Yes, hi everyone. My name is Kagamine Len. I don't have a lot of interests, though. Please to make your acquaintance. - He bowed.
A girl seated besides him got up.
- Good morning, my name is Kagamine Rin. Nice to meet you.
Len took a glance at the girl whose surname was the same as him. She had short blond hair, and was wearing a lot of clips on her hair. She looked kinda like him. Her eyes were blue, but lighter than that of Len.
- Oh? Love at first sight? - A voice suddenly interrupted his thought.
- Eh? - Len's face was red. He turned to look at the person distracting him
That boy seated in front of Len.
- Who are you? - Len asked.
- Your classmate, obviously! - the man answered mischievously.
It's his turn to introduce.
- Nice to meet all of you! My name is Kaito Shion. I hope we'll have a good semester. - the blue-haired boy introduced.
Len's eyes widened.
- Kaito Shion-kun?
Although his voice was small like whisper, Kaito still heard it. When seating down, he asked:
- You...know me?
Len looked at him.
He was really Kaito Shion.
- You must have forgotten me. - Len smiled weakly.
The girl sitting next to Len began to say something.
- Stop talking please, the teacher is looking at you. - Her voice was clear and calm.
Len and Kaito took notice of this and straightened up.
- Could you please explain why you're talking in my class? - the teacher looked pissed.
- We...we just...
- Stop excusing! Ms. Kagamine Rin, you sit next to them, could you please tell me what they're talking about?
Len and Kaito looked at Rin. With a calm face, she said:
- Nothing much, teacher. They just exchanged their way of studying, so you don't have to punish them.
Len and Kaito were quite surprised by Rin's answer. The teacher looked at three of them and shook his head.
- Alright, if it's for educational purposes... I will let you off. But stop talking.
- Yes,sir. - they both answered simultaneously.
Just then another student walked into the classroom.
- Sorry, teacher. I'm late.
He had light pink hair, with green eyes.
As he stepped into the classroom, Len noticed something was strange. Rin, who was looking calm, suddenly turned angry and looked fiercely at the new comer. Kaito smirked annoyingly.
- Brat... - He muttered.
As Len turned his eyes to Rin, the girl was shaking endlessly.
- I...will...kill...him... - it's all she can say.
