On December 2007, Ryo submitted his song "Melt" (メルト Meruto) to NicoNicoDouga using the Vocaloid singing synthesizer software, Hatsune Miku, for the vocals. This song was very well recieved, adding to the fact that Hatsune Miku's popularity was soaring high at that time, it garned 5 million views since then.
However, Ryo used an illustration of Miku drawn by 119 (pronounced Hikeshi) without permission. Hence prompting Ryo to contact 119 to apologize, 119 responded with a great interest on "Melt" and the both of them began working together, forming supercell in between.
