"The Great Banquet" is a maimai original song by the artist Iris, first appearing in maimai でらっくす BUDDiES on February 2, 2024. It stands out among maimai's original catalog for its lyrical content: the song directly retells the Parable of the Great Banquet from the New Testament (Matthew 22:1–14 and Luke 14:15–24), a choice confirmed by the official music video's description. Iris handled composition, arrangement, lyrics, and vocals in-house, while the music video was produced by the duo あるし / かわく. Within the game's narrative framework, "The Great Banquet" is tied to the 7sRef storyline series, serving as a challenge track (課題曲) in 7sRef Area 3. The flavor text accompanying the song follows the character Liz (リズ), an observer of the 7sRef realm who grows fascinated by the "fragments" carried only by wanderers. Lacking a fragment of her own, she attempts to create one using old laboratory equipment, only to accidentally shatter a test tube when a mysterious voice warns her not to touch its contents, a moment of disruption mirrored in the song's ominous, driving energy. The DX charts span Basic (4), Advanced (8), Expert (11), and Master (14). The Expert chart was designed by サファ太 (Safata), while the Master chart was designed by Luxizhel. The Master chart's 953 notes include 131 Slide notes, giving it a notably slide-heavy profile for a level-14 song. Initially unlocked by accumulating 850 km of total distance in 7sRef Area 3, the track became available by default starting from maimai でらっくす PRiSM, with staggered unlock dates across Asian and Chinese regional versions.
