Yume Hibana (ユメヒバナ, "Dream Spark") is a maimai original song by the doujin music circle RD-Sounds, featuring the vocals of Mitsuki Nakae (中恵光城). It debuted in maimai でらっくす Splash on December 11, 2020, as part of the Sky Street area (スカイストリートちほー), a narrative-driven region that tells the story of a mysterious nocturnal dance troupe in traditional Japanese clothing. When night falls, the group appears without warning and transforms ordinary streets into an otherworldly, dreamlike spectacle, a guerrilla performance that draws crowds every evening. The troupe's leader, Akatsuki, becomes caught in an inexplicable incident and finds a butterfly mark carved into his wrist, setting him on a path to pursue a net master known as "Noa" who shares the same butterfly emblem. Composed, arranged, and written by RD (the principal behind RD-Sounds), the track sits at 151 BPM and runs 2:02 in length. The music video was produced by the artist 群青リコリス (Gunjou licorice). Yume Hibana is widely recognized as a spiritual successor to ユメキキョウ (Yume Kikyou), a song RD-Sounds previously contributed to SEGA's CHUNITHM AMAZON PLUS, both feature Nakae on vocals and share the "ユメ" (yume, "dream") motif in their titles. In maimai, the song's chart lineup spans Basic through Master, with the Master chart (level 13.4, designed by ぴちネコ) standing out for its dense Touch-note placement (116 Touch notes out of 731 total), giving it a tactile, pattern-heavy character distinct from many other level-13 charts in the Splash era.
