BackgroundEdit

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.

Many PVs present Rin's scientist being Kagamine Len.

This song is featured in the Miku no Hi Dai Kanshasai 39's Giving Day concert, the MikuPa Live in Tokyo 2011 concert, the MikuPa Live in Singapore 2011 concert, the MikuPa Live in Tokyo 2012 concert, the MikuPa Live in Hong Kong and Taiwan 2012 concert, the MikuPa Live in Sapporo 2013 concert and the MikuPa Live in Kansai 2013 concert; also in the games Project DIVA 2nd, Project DIVA Arcade and Miku Flick/02 (DLC). It has also been featured in a stage play and a novel adaptation.

ココロ・キセキ (Kokoro・Kiseki / Heart Miracle)

	Category:	Arrange
	Featuring:	Kagamine Len
	Nicovideo Broadcast Youtube Broadcast
Description One of the most popular and famous derivations of "Kokoro" is "Kokoro・Kiseki" composed by Jun-P and sung by Len. "Kokoro・Kiseki" serves as a prologue to "Kokoro", telling the story of the scientist who created the robot in "Kokoro". Short after create the robot, the scientist realizes she is missing something important: her kokoro. Whishing to share happiness and sadness with her, he begins to work tirelessly at creating a heart 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. Though there is no clue who the scientist is in "Kokoro" and despite in "Kokoro・Kiseki", Len is not directly portrayed as the scientist, after the release of Jun-P's work, many PVs depicting Len as the scientist were made. There is also a mixed version "Kokoro" and "Kokoro・Kiseki". The songs 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. This cover is featured in the EXIT TUNES compilation album Vocalogemini.
