化けの花 (Bake no Hana) is a VOCALOID song by Japanese producer nakiso (なきそ), featuring Hatsune Miku on vocals. The track was originally commissioned for the mobile rhythm game Project Sekai: Colorful Stage! feat. Hatsune Miku, written for the unit 25-ji, Nightcord de. (25時、ナイトコードで。), a group whose songs frequently dwell on isolation, emotional fragility, and the tension between outward appearance and inner truth. Released as an album track in 2024, the song made its arcade rhythm game debut in CHUNITHM X-VERSE-X at launch before arriving in maimai でらっくす CiRCLE on January 9, 2026, under the niconico & VOCALOID genre category. The title 化けの花 operates on dual meanings: 化け (bake) can signify a disguise or a monster (as in 化け物, bakemono), while 花 (hana) means flower, together evoking the image of a deceptive bloom or a monstrous flower that cannot return to its bud. Nakiso's lyrics revolve around concealing one's true self behind a mask, captured in the recurring plea: "見ないで 理解出来ないでしょう? / まるで咲いてしまった 化けの花" ("Don't look at me, you wouldn't understand, would you? / Like a blooming monster flower"). At 180 BPM, the arrangement balances driving energy with a tense, anxious undercurrent that mirrors its lyrical themes. In maimai, the song's DX charts span Basic (level 4) through Master (level 13.4). The MASTER chart, designed by サファ太 (Safata), makes notable use of Touch notes alongside dense Tap and Slide patterns, while the EXPERT chart (level 11.0) was designed by アマリリス (amaryllis). The music video was produced by Samejima Nurie (鮫島ぬりえ).
