Saint Vega is a two-piece unit consisting of Osaka-based rapper/singer/trackmaker Vega Merceline and trackmaker Maybe Juice. This is the second single of 2021, and it is a new level of personal expression. The song is a piano-driven rap about expectations for the future that "swells up like a balloon". Inspired by the lyrics, the artwork was created by miso, who is active in various fields including artwork for iCE KiD.
