やなぎなぎ
This single was the first release by Supercell which did not use the Vocaloid singing synthesizer Hatsune Miku as the vocalist, as they had done for their debut album "Supercell" (2009). Instead, Supercell employed the singer Nagi Yanagi, a vocalist who had previously submitted cover versions of songs to the Nico Nico Douga video sharing website under the name Gazelle. The single peaked at No. 5 on Japan's weekly Oricon singles chart, and in February 2010 was awarded a Gold Disc by the Recording Industry Association of Japan for having exceeded 100,000 copies shipped in a single year.
