The Master chart originally debuted at level 12+ in UNiVERSE PLUS and was later re-evaluated to level 13 starting with the FESTiVAL version, reflecting the chart's sustained demand on player stamina and pattern-reading ability. The accompanying video was produced by Sam and yozba, complementing the song's atmospheric interstellar imagery with a visual style that mirrors the cosmic drift of its lyrics.
