 * In Kokoro , Rin is a robot made by a lonely scientist, but she is missing something that can't be found in a program: a heart and a mind. Many years after her creation, her creator passes away, leaving her alone for several hundred years. Eventually she begins to wonder about the man who created her, and accesses his research. Discovering more and more about the reason the scientist created her and her kokoro, the robot is moved and is awakened to a world of new feelings. However, the kokoro which she found herself was too great for her fake body, and after some time the robot passes away.

ココロ・キセキ (KOKORO/KISEKI) / (Heart or Soul/Miracle)
Sung by Len Kagamine

Music and lyrics arranged by Jun-P (Zyun)

 * One of the most popular and famous of these derivations is KOKORO/KISEKI (Heart or Soul/Miracle) by Jun-P/Zyun-P. Though there is no clue who the scientist is in KOKORO, Jun-P let Len sing the story of the scientist who created the robot, arranging the original music and lyrics with her own interpretation, also using some parts of the original song and mixing them together. In KOKORO/KISEKI, Len is not directly portrayed as the scientist, but after Jun-P uploaded it, many PVs depicting Len as the scientist were made.


 * KOKORO/KISEKI serves as a prologue to KOKORO, telling the story of the scientist who created the robot in KOKORO. The scientist creates a robot but realizes that she is missing something important: her kokoro. He wishes to share happiness and sadness with her, and so he begins working tirelessly at creating a heart and mind for her. However, the time is running out for his life will eventually come to an end. As he begins to lose hope, a miracle (KISEKI) suddenly happens: he receives a message from the robot from the future, after she has created her own kokoro. The scientist obtains peace and passes away in tranquility.


 * There is also a second version of KOKORO and KOKORO/KISEKI mixing together both songs, this time to form a more involved and different take on the story. The first half of the original songs are played separately, one after the other. The first is told from Rin's point of view, and then Len's. The songs then switch between one and the other and eventually resulting in a crescendo of both songs finales being played in unison. As the melodies of the two songs were written to complement each other, the final effect is a complete and harmonious experience.

Kokoro lyrics
Romanji

Kodoku na kagakusha ni tsukurareta robotto dekibae o iu nara "kiseki"

dakedo mada tarinai hitotsu dake dekinai sore wa "kokoro" to iu puroguramu

ikuhyaku toshi ga sugi hitori de nokosareta kiseki no robotto wa negau

shiritai ano hito ga inochi no owari made watashi ni tsukutteta "kokoro"

ima ugoki hajimeta kasoku suru kiseki nazeka namida ga tomaranai... naze watashi furueru? kasoku suru kodou kore ga watashi no nozonda "kokoro"?

fushigi kokoro kokoro fushigi watashi wa shitta yorokobu koto o fushigi kokoro kokoro fushigi watashi wa shitta kanashii koto o fushigi kokoro kokoro fushigi nande fukaku setsunai...?

ima kidzuki hajimeta umareta riyuu o kitto hitori wa sabishii sou, ano hi, ano toki subete no kioku ni yadoru "kokoro" ga afuredasu

ima ieru hontou no kotoba sasageru anata ni

arigatou... kono yo ni watashi o unde kurete arigatou... isshoni sugoseta hibi o arigatou... anata ga watashi ni kureta subete arigatou... eien ni utau

English

A lonely scientist developed a robot The result was said to be a "miracle"

But it wasn't yet sufficient; there was just one thing he wasn't able to do And that was the program known as a "heart"

Hundreds of years pass Left alone The miracle robot wishes

I want to know, why Until the end of that person's life He built a "heart" For me

Now, movement has started, the miracle is accelerating Why? My tears don't stop... Why am I shaking? The beat is accelerating This is the "heart" I hoped for?

Mysterious, heart, heart, mysterious I know; there are things to be happy about Mysterious, heart, heart, mysterious I know; there are things to grieve about Mysterious, heart, heart, infinite How deeply painful...

Now, I've begun to realise the reason I was born Being on your own is surely lonely Yes, that day, at that time All the memories dwelling in my "heart" begin to overflow

Now, I can speak true words I dedicate them to you

Thank you... for bringing me into this world Thank you... for the days we spent together Thank you... for everything you have given me Thank you... I will sing for eternity
