"Sekiranun Graffiti" is the opening theme of the video game Hatsune Miku -Project DIVA- extend. With music and lyrics by two of the most prominent VOCALOID producers, ryo and Dixie Flatline, the song is accompanied by a well-executed anime music video depicting Miku flying among clouds. It is interesting to note that "sekiranun" translates to "cumulonimbus", a type of cloud that can develop into a supercell storm.
