Moon

Background
iroha(sasaki)'s first original Vocaloid work. The lyrics are somewhat vague, but a common interpretaion is that Miku is in fact the moon, and is singing about always being by mankind.

This song is featured in the Miku no Hi Kanshasai 39's Giving Day, the Mikunopolis in Los Angeles Concert and the Miku no Hi Dai Kanshasai 39's Giving Day; also in the games Project DIVA 2nd, Project DIVA Arcade and Miku Flick.
