Overview
インビジブル (Invisible) is a VOCALOID original song by the producer kemu, first uploaded to niconico in 2011 on kemu's debut album of the same name. The track features dual vocals from GUMI and Kagamine Rin, with tuning by おればななP, accompanied by an animated PV from illustrator ハツ子 and video editor ke-sanβ. Its Japanese title translates to "Invisible," and the tagline printed on the jacket, "少年はよだかになりたかった" ("The boy wanted to become a nightjar"), echoes the themes of Kenji Miyazawa's short story "よだかの星" (The Nighthawk's Star). The lyrics revolve around a protagonist who has become a transparent/invisible person, wrestling with self-hatred and a desire to disappear while simultaneously craving acknowledgment, captured in recurring refrains like "大嫌い嫌い嫌いな僕" (the me I hate, hate, hate).
In maimai, インビジブル arrived with the MiLK PLUS update on August 7, 2018, notably receiving its Re:MASTER chart on the same day as the base song, an early signal of the track's enduring popularity among high-level players. The song's difficulty ratings underwent several rebalancing passes across subsequent versions (from でらっくす through FESTiVAL), with the Expert, Master, and Re:MASTER levels all being raised over time as the game's overall difficulty curve tightened. The Master chart (12.3, designed by 緑風 犬三郎) features an unusually high proportion of Slide notes, 156 out of 730 total, giving it a flowing, dense feel, while the Re:MASTER (13.7, by 華火職人) pushes the note count to 939 at a relentless 192 BPM. Outside maimai, インビジブル also crossed over into CHUNITHM (first appearing in AIR in 2016, before its maimai debut) and later オンゲキ SUMMER, making it a fixture across all three of SEGA's major rhythm game franchises.

Trivia
- The song's tagline "少年はよだかになりたかった" (The boy wanted to become a nightjar) is a direct reference to Kenji Miyazawa's 1934 short story "よだかの星" (The Nighthawk's Star), in which a despised nightjar bird transforms into a star to escape its suffering. The same phrase is used as the title of the in-game collection achievement (称号), unlocked by earning SSS rank on the MASTER chart.
- インビジブル was kemu's debut album, released in 2011. The album's only vocal tracks are this song and its sequel "インビジブル -a king of nothing-," with the rest being instrumental BGM pieces. kemu's works were part of the early-2010s VOCALOID boom on niconico, and he later went on to produce for mainstream artists under the name 中村遥 (Haruka Nakamura).
- The CHUNITHM MASTER chart for インビジブル was designed by a charter credited as ルンパッピー, a name lifted directly from the lyric "ルンパッパ" that appears in the song's chorus (\"見えてますかルンパッパ\"). This cross-game charter name is a playful nod to the song itself.
- The MV was created by the same duo, illustrator ハツ子 and video editor ke-sanβ, who collaborated on several of kemu's other early VOCALOID works. ke-sanβ is particularly known for stylized, fast-paced PVs in the niconico VOCALOID scene.
- The vocal tuning credit goes to おればななP (Oreba Banana-P), a well-known tuner in the VOCALOID community who has worked on numerous kemu tracks. The song uses GUMI (Megpoid) and Kagamine Rin, both iconic VOCALOID voicebanks.
- インビジブル was added to CHUNITHM AIR on November 17, 2016, nearly two years before its maimai debut, making its first rhythm-game appearance on SEGA's other arcade title. It later returned to CHUNITHM SUPER STAR PLUS on October 14, 2021 with its MASTER chart raised to level 14.
- In Asian English versions of maimai MiLK PLUS, the song title is left in its original Japanese form インビジブル without translation or romanization, preserving the kanji/kana display.
- The maimai jacket illustration, by ハツ子, depicts a surreal scene: a school-uniform-clad figure with long black hair sits on a chair, their face partially obscured and surroundings fragmented, reflecting the song's theme of invisibility and fractured identity.
- Over the course of maimai's version history, all five Standard charts underwent level adjustments. The Basic chart rose from 3→6, Advanced from 7→8, Expert from 9+→11, Master from 10+→12, and Re:MASTER from 12+→13+, reflecting the game's gradual upward difficulty recalibration across でらっくす, Splash, UNiVERSE+, and FESTiVAL.
- The song's duration in its original album version is approximately 2:10, a compact length typical of kemu's niconico-era VOCALOID production style.
