BackgroundEdit

"Heart" is an original song by Toraboruta-P.

The song tells a story about a robot (Rin) made by a lonely scientist, but is missing a program unable to be made: a heart. Some time after her creation, her scientist passes away, leaving her alone for several hundred years. She begins to wonder about her creation and makes a wish. She accesses the files that her creator had left and finally gains a heart. In the process, she discovers what it's like to be happy and sad. With her new feelings, she gratefully dedicates all of the songs that she sings to her creator. In the end, the miracle robot had a short in her system and could no longer sing. However, she had a smile on her face in her last moments, resembling an angel.

A prequel named "Sayonara Arigatou" was made for the album of the same name. It tells the story of the robot's creation and the making of the heart told from the scientist's (Gackpo) point of view.

This song has entered the Hall of Legend.

LyricsEdit

Japanese (日本語歌詞) Romaji (ローマ字)
孤独な科学者に作られたロボット kodoku na kagakusha ni tsukurareta robotto
出来栄えを言うなら”奇跡” dekibae o iu nara "kiseki"
だけどまだ足りない 一つだけ出来ない dakedo mada tarinai hitotsu dake dekinai
それは「心」と言うプログラム sore wa "kokoro" to iu, puroguramu

幾百年が過ぎ ikuhyaku toshi ga sugi
独りで残された hitori de nokosareta
奇跡のロボットは願う kiseki no robotto wa negau
知リタイ アノ人ガ shiritai ano hito ga
命ノ 終リマデ inochi no owari made
私ニ 作ッテタ 「ココロ」 watashi ni tsukutteta "kokoro"

今 動き始めた 加速する奇跡 ima ugoki hajimeta kasoku suru kiseki
ナゼか ナミダが 止まらナい・・・ nazeka namida ga tomaranai…
ナぜ 私 震える? 加速する鼓動 naze watashi furueru? kasoku suru kodou
こレが私の望んだ「ココロ」? kore ga watashi no nozonda "kokoro"?

フシギ ココロ ココロ フシギ fushigi Kokoro Kokoro Fushigi
私は知った 喜ぶ事を watashi wa shitta yorokobu koto o
フシギ ココロ ココロ フシギ fushigi kokoro kokoro fushigi
私は知った 悲しむ事を watashi wa shitta kanashimu koto o
フシギ ココロ ココロ ムゲン fushigi kokoro kokoro mugen
なんて深く切ない・・・ああああ~~ nande fukaku setsunai… aaaahhh~

今 気付き始めた 生まれた理由を ima kizuki hajimeta umareta riyuu o
きっと独りは寂しい kitto hitori wa sabishii
そう、あの日、あの時 sou, ano hi, ano toki
全ての記憶に宿る「ココロ」が溢れ出す subete no kioku ni yadoru “kokoro” ga afuredasu
今 言える 本当の言葉 ima ieru hontou no kotoba
捧げる あなたに sasageru anata ni

アリガトウ・・・ この世に私を生んでくれて arigatou… kono yo ni watashi o unde kurete
アリガトウ・・・ 一緒に過ごせた日々を arigatou… isshoni sugoseta hibi o
アリガトウ・・・ あなたが私にくれた全て arigatou… anata ga watashi ni kureta subete
アリガトウ・・・ 永遠に歌う arigatou… eien ni utau

Written by an unknown artist, this version of the lyrics was used in the English version of Hatsune Miku -Project DIVA- F 2nd.

A robot made by a lonely scientist
In almost every way a "miracle"
But this miracle wasn't enough
There was one thing it couldn't run:
A program called "Kokoro"

Centuries pass
Left all alone
The miracle robot pleads
I want to know how he felt
Working till his dying day
Making it for me
My "Kokoro"

Just now it started, a quickening miracle
For some strange reason the tears won't stop
Why am I shaking? The accelerating beat
Is this the "Kokoro" I wanted?

Now I can say these words of truth
And offer them to you

Thank you…
For bringing me into this world
Thank you…
For the days spent together
Thank you…
For all you've given me
Thank you…
Forever I'll sing

Novel adaptationEdit

Toraboruta-P announced that on April 27, 2012; (previously it's stated to be April 17, but it was delayed) he will release his novel entitled "Kokoro", a novel based on the song.

The novel is written by Katsuyoshi Ishizawa and illustrated by Nagimiso.SYS, an illustrator most notable for his PV of "Roshin Yuukai" also a card illustration by redjuice. The price is 1,200 yen and was available for purchase in Amazon on April 27.

A crossfade of the novel ("Kokoro" arrangement by Toraboruta-P and video by Nagimiso.SYS) can be seen on niconico and YouTube. A month after the novel was put on sale on Amazon, it was announced that the "Kokoro" novel had sold out and could no longer be purchased from Amazon. There is currently no news of a second wave of printing; it has sold faster than expected.[2]

The novel tells the story of a group of scientists who worked on realistic-looking robots. Their works included 'Number 02' (Kagamine Rin) and 'Mirai' (Hatsune Miku). One of the scientists wished to install the Heart, a program that allowed the robots to have feelings, into Number 02. However, the others refused, due to the fact that a few years back, when they installed the program into 'Number 01 Rin', the robot went insane and killed a scientist named Kagamine Rin. The robot has since be modified into 'Number 02'. The Heart, which still contained memories of Rin, was secretly installed into Number 02. Many centuries later, Number 02 woke up and and found out that she was surrounded by a search party. There she meets 'B' (Kagamine Len), who explains to her that they were looking for the Heart. Number 02 then explains the origins of the Heart…
