-Soleil- was first uploaded on June 25, 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). It has entered the Nico Nico Hall of Fame.
