Chapter Three: Vocaloid . exe

The first thing Len did when he woke up was getting back on the computer. He didn't care that it's SLIGHTLY unhealthy to be obsessed with an internet stranger, he just knew that he HAD to speak with _r3b00t_. After a full week of filling her in with his personal life, it was time to find out about hers. And sure enough, she was online:

(9/11/13 7:48 am) bananakagamine02: Who exactly ARE you?

_r3b00t_: Excuse me? Has something been bothering you, Len?

bananakagamine02: I know you had something to do with the accident yesterday. You were the one who had called Iroha, weren't you? If you hadn't, she would've been killed. I just wanted to thank you for that, and for your company. That's why I want to know your name.

_r3b00t_: That's very kind of you, Len. And you are already looking at my name.

bananakagamine02: I know, but your REAL name. And what you look like, maybe? So I can thank you in person.

Len was actually desperate to get her name, because he was curious how she knew so much about him. How she got ahold of his house's number, and the way she knew about his problems and such.

_r3b00t_: I'm afraid that's my official name. I'm not like you. I've been assigned a supposed life and personality, one with unclear origins. That's all I am, hun. I'm what they call an Electric Angel.

bananakagamine02: You're an angel...? S-so...you're not actually living?

bananakagamine02: Was that why you saved Iroha? not to mention how you helped me?

_r3b00t_: Yes, I don't know, yes, and yes.

bananakagamine02: Please...I can't dismiss you like this. :( Is there anything you can do so that I know who you are?

_r3b00t_: I know this may violate a majority of the policy, but I was programmed to have a rebellious nature anyhow. When I was created, I was given a name, screen name, gender, a partial history, and an artificial heart. I'm not sure if I'm living or not, but I have a mission: to comfort you. You may know me as "_r3b00t_", but my name is Rin Kagamine. And somewhere, at some time, I had a brother.

Len's breath caught into his throat, as he fell back from his chair. He stared at the blank ceiling above him, his heartbeat in his ears. _r3b00t_ messaged him again and again, but he didn't get up from the ground. He felt like sinking into it.

_r3b00t_: That's about all I can remember, heh.

His dead sister...? Was it true that she had came back from the other side, and became an "Electric Angel," just so she could bring him company? It seemed like a fairytale, a science-fiction movie being played out in front of him. How...how could something like this be possible?

_r3b00t_: Hey, are you still there?

Maybe it was just a prank. Maybe it was the kids from school trying to mess with him, or even scare him by acting like his sister speaking to him from the dead. Maybe he was going crazy, after all. The sudden feeling of nostalgia when he had first met _r3b00t_ was explained.

_r3b00t_: Len? Why aren't you replying...? :/

bananakagamine02: rin...i need to tell u something

He was too distraught to use capital letters and correct punctuation. He typed out a paragraph long message explaining that she was his sister, and that the brother she was unfamiliar with was actually him. Len gave a description of her, right down to the type of pajamas she used to wear to bed. And lastly, he told her that Rin had died at age fourteen. "You're not programmed," he told her. "Your personality is exactly like hers. You're Rin."

_r3b00t_:...

_r3b00t_: It all makes sense now,that feeling that something that was a part of me was missing. Is it true, that I am your sister?

bananakagamine02: Yes.

_r3b00t_: I feel...manipulated. Like life was only made to feel like a dream. Or a dream that turned out to be real life.

_r3b00t_: If all that's true, Len, then it's time for you to see this.

_r3b00t_ has sent an attachment: " Vocaloid . exe " (Save) (Download)

Len could barely believe that he was having this conversation. With a trembling hand, ran the program through several security systems. A computer geek can't help his habits, you know.

Finally, he opened the file. It was a large thing, taking up almost a hundred megabytes. What on earth could this be, he pondered.

It took a while for to start. Len wondered what the word vocaloid meant. Was it some sort of robot? Once the program opened, he could see piano keys going up on the side, each individual key becoming a bar of music. It was like a piano turned onto its side, and words could be imputed as well. But underneath that was something else, something much different. A pixelated sprite, with blond hair and a white bow, was sleeping.

"Rin..." Len whispered. He had no idea what the program was for, but he didn't want to exit just yet. He nervously moved his cursor over the sprite, and it instantly woke up. The chibi Rin yawned, her big blue eyes blinking. She looked at him, and smiled.

Len returned the smile. He moved the cursor over her again, and soon she was laughing. Apparently, he was tickling her.

Mini Rin interacted with him, and does casual things when he's not doing anything. Most of the time, she stared at him, with a thin smile on her lips. Sometimes she'd try to grab the cursor as it come towards her, and then fall on her bottom if she misses. She would also straighten her bow, count her fingers, dust off her shirt, and spin in circles.

It was all very cute to Len, even though she was clearly waiting for something. Len turned to the piano keys, inserting random syllables into the bars. Mini Rin watched him intently as he hit the Play button.

To his delight, Mini Rin started singing the syllables, with the note that the word was placed on. Of course, it was completely random, so it didn't sound very good. But the voice was clearly Rin's, and it nearly brought tears to his eyes.

After singing, Mini Rin suddenly blurted out: "MORE!"

So Len did. He made her sing Twinkle Twinkle Little Star, Sakura, and the theme to his favourite anime show. Then he made her say things Rin would say, although her voice was still musical.

"Daisuki dayo!" Mini Rin squeaked, spreading out her arms. Small heart animations appeared around her, and she reached out to hug the cursor.

Len laughed. For the rest of the day, Len played with the Vocaloid Program and Mini Rin. Once he logged into the chat-page, he found that _r3b00t_ had totally vanished. There was no trace of her ever being there, and their messages. Although he felt remorse at this, Mini Rin spoke to him from the Vocaloid Program minimized from the screen.

"Reboot is Rin! Reboot is Rin! And Rin is me~~!" She hopped up and down. Len now noticed that she had cute, rounded angel wings on her back. So this was what _r3b00t_ meant about that electric angel part.

"Arigato, Onii-chan. You taught me how to sing again~"

Len felt tears slid down his face, but they only complemented his smile. To distract Rin from his sentimentality, he tickled her again.

a/n: :3 I wish Vocaloid actually HAD Mini Vocaloids... T^T
