ソレイユ -Soleil-

Background
-Soleil- was first uploaded on June 25th 2012; without a PV. It was uploaded as one of "Miku's Creator" Project on Google+, and Toraboruta-P was one of the first producers interviewed and invited to the project. The project took three months with steps and tutorials uploaded for the song by Toraboruta-P (Matsumura Takumi also made a brief introduction to the flute for the song to Soleil).

Although the song was finished on June 25th and was uploaded to Toraboruta-P's YouTube; it was incomplete for the PV was scheduled to take another month as well. CHRIS, like Toraboruta-P, set deadlines such as "finishing illustration", or "begin video making". There were stages of concept arts as shared by CHRIS. Later, on September 11th, the PV was finished and Toraboruta-P uploaded it to his Nico Nico Douga account and YouTube.

Like many other Toraboruta-P's works, his song tells stories; much like Kokoro, Toeto, or Soratobazu. In this, it tells a story of a girl (Rin), who wanted to save people in despair (in this case, the darkness). She sacrificed herself without knowing her limits, until Soleil (Len) took her away.
