Sekiranun Graffiti is a one-episode music video set to the title track of an EP by the Japanese pop act Ryo (Supercell). Sekiranun translates to thundercloud, and the song also serves as theme music for a Hatsune Miku Project DIVA game on arcade and PSP. Sony Music Direct (Japan) brought the EP to the U.S. as a follow-up to the act's first full-length record there. The release pairs the title track with the new single "Fallin' Fallin' Fallin'," written by Ryo together with Vocaloid producer Dixie Flatline, along with instrumental versions and remixes of both songs. Atsuya Uki provided the cover art. The result is a short slice-of-life adventure music video.
