"Falling" is an original maimai song by composer Shino (シノ) featuring vocalist Shiho (しほ), first introduced in maimai でらっくす FESTiVAL in December 2022. A gentle ballad at 122 BPM, it serves as a key narrative piece within the Sky Street Area 3 (スカイストリートちほー3) story arc, a multi-chapter narrative that runs across several maimai DX releases. The song's music video was produced by MiRA (STUDIO KAIBA) and しょくむら. The song is accompanied by an unusually elaborate in-game flavor text (フレーバーテキスト) that expands the Sky Street storyline. Written from the first-person perspective of a narrator within the character Kohaku (コハク), the text describes Kohaku's complicated feelings for her childhood friend Akatsuki (アカツキ), a bright, gifted boy who enrolled in the experimental Sky Street academy and pulled the reclusive Kohaku in with him. The narrator, whose own identity is tied to the name Noa (ノア), observes Kohaku's life from within like a spectator behind a stage curtain, knowing that Akatsuki's warm smiles are meant for Kohaku, not for her. The flavor text ends with a fragment of a promise: "Noa, promise me. You must, ," hinting at a larger narrative spanning the Sky Street series. The lyrics, written by Shino, use falling flower petals as a central metaphor, petals fall, the narrator falls, and the song traces the arc of unspoken love, quiet devotion, and inevitable parting. With lines like "Even if I wish for anything, I am powerless" and "Goodbye, I'm tired of saying it," the song carries a melancholic, wistful tone that complements the story's themes of one-sided affection and the passage of time.
