A few years ago, was born a worldwide phenomenon of new musicians, realizing albums, figurines and even concerts. That was the beginning of the VOCALOID. Originally the VOCALOID began from the simple concept of synthesizing the human vocals for singing and the companies succeed versions of voice synthesizing applications have been sold commercially since then.

My name is Kagamine Len, codename: "CV02" means "Character Voice 02", a male Vocaloid. Me and Kagamine Rin were at first just a simple pair of voicebanks developed by Crypton Future Media. Therefore, we became popular among the humans and later we gain a real body, created by the company. We are almost organic, we like to eat, to sing and play like anyone, but they refer to us as Vocaloids. Our bodies were designed to appear 14 years old teenagers, we have the same blue eyes and blond hair. Rin is a female Vocaloid, also I am a bit taller than her. We were born at the same time, but she woke up first on the day we considered our birth. We aren't real siblings, but I've learned the human concept of twins. Rin and I don't share the same genes, but we have the same creator and we share the same surname. I like to think of her as my 'family'.

It was quite strange to woke up and have a body, hair, clothes, I remember waking up in a white and bright room, full of people, like a hospital, but wasn't a real one, and besides me was Rin, confused as me, even with our data about the Earth and their culture, we knew we were different from the humans around us. I can't imagine how was for the other 'androids', as they call our kind, to wake up alone like this. Because, at least, I always had Rin, we are very close to each other, just one look at her to know, since the beginning, that she was like me gave me a comfortable feeling and release me from the fear. We aren't authorized to meet our creator yet, but Patricia (an American female engineer) said that he described us as having one soul between us two, but I don't have any idea of what this mean.

Just after a few months of training and adapting to the work and ourselves that we became able to meet up with the ones whom came before us, the others Vocaloids.

The employees guided us through door after door, until we arrive in a long empty corridor. They left us alone and locked up the door behind us. We were worried. How they would be? They will like us? Rin was grabbling my sleeve, I stopped and hold her hand, we looked at each other and we gave a deep breath. The silence was uncomfortable, but we kept walking.

And then, we heard music.

It began slowly, but became louder as we approached, rushing towards the sound, each step sounded happier at the rhythm of the music, it was exciting! We turned to the right, it was a studio, like the ones that we had worked before, we looked through the glass and there they were! Singing and playing together, in such a perfect harmony! A woman with pink hair, a mature appearance, wearing old-fashioned clothes, black and yellow, long boots. Adorned by gold curl with the infinite symbol on her chest and a jewel on her neck, water-blue like her eyes. The other was a high-school girl, with blue-green pigtails, wearing a school uniform that match with her hair color on the neck tie and some details on her black long boots and black pleated skirt. Their headsets were glowing with the passion of their notes, so inspiring. I looked at Rin, she had the same bright in her eyes that I felt on my heart to listen. I pulled her arm and we ran to the sheet's support, we picked up the music sheets and read the notes. We moved our fingers with the time. As I was reading the notes they fit like the pieces of a puzzle inside my brain! Soon we learned, we started to sing with them. This music called SpiCa.

When the song ended we heard someone clapping behind us.

"Bravo! Very good indeed."

It was a man with long purple hair. He was tall and looked like a Japanese samurai, wearing a Jinbaori, a kind of kimono which was used as a battle robe. But this have parts of an Japanese armor in a cyber-style. More like our style. Another Vocaloids!

"Gakupo! You came!" The pink haired one rushed to him.

"I couldn't miss this meeting. So, who are the newbies?"

Everyone looked at us.

"M-my name is Kagamine Len and she is Kagamine Rin, codename CV02. It's a pleasure to meet you all."

Rin's face was red.

"Oh! They are so cute!" The pigtails girl hugged Rin and then held my hand.

"I am Hatsune Miku, codename CV01. Call me Miku, can I call you Len?"

I felt my cheeks burning.

"S-sure!"

"Don't be shy, you two have beautiful voices. My name is Megurine Luka codename CV03."

She nudged the samurai with her elbow.

"Welcome to the world! I am Kamui Gakupo. Different from you all I was developed by Internet Co. Soon you will meet many Vocaloids created by other companies. I don't believe that everybody will come today, thought."

"Are there so many others?" I asked.

"Of course! With lucky, you can work with the others!" Miku answered.

The door on the other side of the room opened in a burst, I almost had a heart attack! It was a teenager girl, with short green hair, wearing red and white goggles on her head and an orange and green outfit.

"No need for crying anymore, guys! I finally came!" She said, lively.

"So loud…" Gakupo mumbled, annoyed.

Luka giggled.

"Gumi! Come here! These are Kagamine Rin and Len. Guys, she is Megumi, also from Internet Co. like Gakupo." Miku said.

"Just Gumi, please! Oh! Hmmm…" She curved her body to look at our faces closely. She was taller than us.

"You are identical! Are you twins?"

"Well… We born at the same time." Rin answered.

"Oh! So cool! I wish I could have a brother like me."

"Two Gumis? It would be too much for me." Gakupo said.

Miku and Rin laughed.

They seemed to have a very close relationship, like a family. Before, was just Rin and me. We shared the same room, the same home, same routine, everything together.

"You live together?" Rin asked.

Gumi looked at her, surprised.

"No surprise that you are being shy, you two know nothing apart the Crypton schedule of work, right?"

"What do you mean?"

"You don't know what you are missing, let us show to you!"

Miku grabbed our hands and with the others leaded us to outside de building, there were no guards, or engineers, not even the production in our way now.
