Chapter 1: Getting started.

He was running away... away from the darkness that was going to consume him. However, exhaustion soon got better of him, and he fell to the ground.
- Ahh... - The boy uttered the sound. His breath was getting colder due to the weather, and his whole body was too tired to get up on its own. His mind, his body was heavy . The boy, around twelve years, collasped in a middle of a night storm. Unable to do anything other than resting for a bit, he averted his eyes to the sky to see the , a crescent moon appeared with dark black clouds. No matter how dark they are, the moon just stood out in a midde of the sky. To the boy, this beautiful scenery was a invaluabe gift to him. It was so simple, so peaceful, so charming, so attractive. As he lost in his thoughts, he gradully closed his eyes, letting his dark black hair down, and fell to the deepest sleep.

2 years later...
A girl was walking towards a house. She had teal hair that slid to two sides and was wearing a simple T-shirt. The house she was heading for was a big white house with beautiful trees and flowers. The girl looked quite sad, though she tried her best to hide it. As she was knocking on the door, she sighed deeply.
- Hello? Len-kun. Are you home?
No response.
- Len-kun. Are you home? I have something important to tell.
No response. The person she was calling wasn't at home.
- Damn. - She muttered under her breath.
As she was going to go back to her place, a boy was right behind her.
- Hi, Miku-chan. What are you doing here? - The boy asked. He wasn't a very tall boy, but very handsome. He had blond hair that he made into a ponytail. He was wearing a black shirt and a headphone. This boy looked somewhat sad and depressing, but since he looked like that every day, the girl didn't feel strange.
- Len-kun...Um... I... I have something very important to tell you. Could we talk at the cafe? - The girl whose name was Miku Hatsune asked.
- Sure. - The boy named Len Kagamine looked quite confused at his friend's reaction. Miku was a cheerful girl, and this kind of atmosphere didn't suit her at all. He had a premonition that the topic they were going to talk about wasn't comfortable.
At the cafe...
- So what do you want to talk about? - Len asked.
Miku looked hat him, and tried her best to hide her emotions.
- Have you... looked at the exam's result yet? - Miku asked.
- The exam... Ah, isn't that the high school's entrance exam? Yes, I've seen it.
- What school...are you intending to go? - Miku asked more anxiously.
- The... Vocaloid...high school in Tokyo. - Len smiled. - I've never thought I could get into that prestigious school. This news took me aback, really. What about you?
- Um... - Miku stuttered. - I only got into a school here in Kansan. I couldn't go to the same school with you.
So this was the reason why she was so nervous. She had been with Len primary and secondary school, and she hated the idea of being separated with him. Len also understood this. He smiled lightly and talked to his best friend.
- Don't worry, Miku-chan. I will always be there for you. If you have any trouble here, call me and I will be there for you. Besides, it isn't like that we would be separated forever. I'll return her once I finish my study, then you can meet me again.
Len's words are so comforting that Miku smiled back to him. She knew they would meet again no matter what, and she would visit him sometimes.
- I'm sorry. I've been too emotional about this. I'm really...really...sorry...
Len let out a sign of relief.
- That's nothing at all. Ok, let's finish drinking your coffee and we have to go home. I got a lot of things on plate since tomorrow is my first day to Vocaloid. I have to leave here this afternoon.
- Sure. I'll give you a helping hand. - Miku smiled cheerfully.
- Thanks...

In Tokyo...
The police station...
- We cannot allow this to happen. - A police officer said.
- But what can we do right now? - Another officer asked. - This is beyond our control. That yakuza group is a monster. We've lost too much already.
- Yeah, chief. We need help from the higher authorities, we can't take it out on our own.
The chief sighed deeply. He felt so helpless.
- No, the authorities won't listen to us anyway. They just cared about some other trivial problems.
- So should we give up on them? - A police officer asked.
- NO WAY! WE CAN'T LET THEM TAKE CONTROL OF EVERYTHING. WE'RE THE POLICE FORCE, THE PRIDE OF JAPAN. WE CANNOT LET PEOPLE DOWN.
- Father, could you turn your volume down please? I might have a hearing problem if you continue to shout like that. - A boy around sixteen years old step inside the police office. He had black hair and rather brown eyes. His style of dressing was odd, as he was wearing a black jacket with white shirt and a pair of purple trousers. However, he did look intelligent.
- Yumma. What are you doing here? - the chief asked his son.
- About the yakuza group, would you mind if I lend you guys a hand? - Ignoring his father, Yumma asked the entire police officers.
Some of them looked at him wide-eye, while others gossiped. All the officers here knew how intelligent he was, comparing with average person. Yumma was known for his sharp deduction and observation. He had helped his father in many cases. Despite all those facts, he was pretty arrogant. Yumma tended to look down on his opponents, so when it came to capture criminals, despite skillful skill, he could hardly capture anyone.
- Son, I know you've been waiting for an opportunity to show yourselves but... this isn't a right time. You couldn't capture them with your skill, and about investigating the members, we've tried many ways.
- You think I come here without preparing for anything? Dad, I've been investigating the case for quite a while, and I could find a suspect. He had every potential of being a member of the Yami organization. I had his picture with me.
Yumma put down a picture.
- A...A... - the reaction was unbelievable. Everyone in the office gasped in surprise.
- A HIGH SCHOOLER?
- Yes. He is about my age. So do you understand what I mean. I can approach him much easier than you guys. All I need you to do is to transfer me to that school.
Everyone remained quiet. Then the chief started to break the silence.
- OK. Do whatever you want, Yumma. But remember not to take too much risk. You can always turn to us for help, and don't undermine your health. Oh, your mother will blow through the roof if she finds out. - the chief sighed in defeat.
- Don't worry, dad. I'll do my best. - Yumma smirked.
