"Showasen★Girl" is an original electronic VOCALOID song by Kagome-P, sung by Kaai Yuki and "DJ G", a fictional, stereotypical black rapper whose voice is actually a filtered version of the VOCALOID2 voicebank Gackpoid. The song was created out of nostalgia for the Shōwa period; its subject matter mainly concerns Yuki being bored with school and interested in boys (80's guys in particular). "Showasen★Girl" is featured on the albums GOOD 2 GO!! and GUILTY? or NOT GUILTY?.
