ココロ (Kokoro)

==Background==
"Kokoro" is a song featuring Kagamine Rin 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 Goodbye, Thank You 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.

|-|Approved English Lyrics =
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

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 been 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 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…
