康莊大道 (Bright Road) is a maimai original song composed collaboratively by Spiegel, an alias of the well-known doujin composer Ice, and Yukino, a Hong Kong-based producer making their maimai debut. The track was added on February 3, 2023, as part of the maimai DX FESTiVAL update and serves as the final Perfect Challenge song for Heavenly Realm Area 6 (天界ちほー6), unlocked at the 1,300 km milestone. The Chinese title 康莊大道 translates to "a broad road illuminated by light." Composer Ice confirmed on Twitter that this meaning directly shaped the song's bright, uplifting melodic character, a deliberate counterpoint to the darker narrative of the Heavenly Realm Area 6 storyline, in which a spreading defilement across the land of Norg threatens the four beast tribes descended from the world's gods. In the maimai DX database, the song's reading is listed as ひかりにてらされるおおみち (hikari ni terasareru oomichi), placing it in the "ha" (は) row for alphabetical sorting on cabinets and in maimai DX NET. On the charts side, the Master difficulty (level 14+, constant 14.7) was designed by ボコ太 (Bokota) and packs 1,129 notes with an unusually high concentration of Touch (140) and Break (114) notes, demanding both stamina and precise technique. The Expert chart (level 13, constant 13.2) was designed by Jack. The in-game background movie was produced by わっふゑ (Waffue).
