「華の集落、秋のお届け」(Hana no Shūraku, Aki no Otodoke) is an original maimai composition by Umiai, the founder and primary artist of the doujin music label sEa-PuLsE. Released for maimai DX UNiVERSE on October 29, 2021, the 165 BPM track blends Umiai's characteristically atmospheric style with a brisk, narrative-driven energy, a signature of the artist, who describes their work as prioritizing mood, world-building, and personal expression. The song debuted as part of Tenkai Chihou 4 (Heavenly Realm Area 4), initially gated behind a "36 km" challenge unlock before becoming generally available on September 15, 2022, coinciding with the FESTiVAL update. Its in-game flavor text weaves a tale of knights fighting for a figure named Mika, aware that their path leads to destruction by darkness, with the character 白法院ラグ (Hakuhoin Ragu) serving as a witness to the fates of those who have fallen from heaven. The DX MASTER chart, designed by あまくちジンジャー (Amakuchi Ginger), is notable for its unusually dense use of Touch notes, 246 out of 890 total, a higher count than any other note type except Tap. The chorus features repeated four-beat patterns where a Touch on beat 1 must be followed by a Slide on beat 2, demanding precise tactile coordination. Nearly three years after the DX charts arrived, STANDARD charts were added on July 19, 2024, as an Otomodachi Taikai Season 18 reward at 300 SP, with both Expert and Master levels charted by サファ太 (Safata).
