STAIRWAY TO GENERATION is the opening theme for Sega's arcade mecha shooter Border Break X, composed by Naoto Oike, arranged by Tomoya Koga, and performed by Yosh, the vocalist of the rock band Survive Said The Prophet. The track was added to maimai MURASAKi at its December 15, 2016 launch, debuting simultaneously on CHUNITHM AIR the same day, an uncommon cross-platform release for a single song. It has remained in the maimai DX catalog ever since, having been recategorized from the original "SEGA" genre (MURASAKi through FiNALE) to "ORIGINAL" briefly in でらっくす, and finally to "GAME & VARIETY" (ゲーム＆バラエティ) from でらっくす PLUS onward. At 150 BPM, STAIRWAY TO GENERATION is a driving rock anthem anchored by Yosh's distinctive vocal delivery and a propulsive guitar-and-drums arrangement. The track originally appeared on the BORDER BREAK X SPECIAL FAN DISC EUST album released in 2016. In maimai, its chart set spans two designers: rioN crafted the Expert (11+) chart, while Jack designed the Master (13+) chart. The Master chart is notable for its unusually high Hold-note count (129) relative to its Slide count (23), giving it a sustained, rhythmically grounded feel that distinguishes it from many peers in the same difficulty tier. The chart's level has been revised upward across maimai versions, starting at 12 in MURASAKi and eventually settling at 13+ by BUDDiES+, reflecting the game's ongoing difficulty standardization.
