Overview
バグ (Bug) is a VOCALOID original song by prolific producer Kairiki Bear (かいりきベア), featuring Hatsune Miku on vocals. Released on September 14, 2023 as part of the maimai でらっくす BUDDiES launch lineup, the track quickly became a standout among the niconico & VOCALOID genre offerings. With a relentless tempo of 186 BPM, the song channels themes of spiraling anxiety, mental entrapment, and emotional breakdown, the title "バグ" (bug/glitch) reflecting the sensation of a malfunctioning psyche. The repetitive, staccato phrasing in the lyrics ("パッパラノーイ「ア」", "ぐるぐる") mirrors the cyclical, inescapable nature of the thoughts it describes. Kairiki Bear, a Vocaloid-P known for high-energy, emotionally charged compositions such as "Darling Dance" and "Venom," brings the same explosive sensibility here. In maimai, バグ features five DX charts designed by three different note designers (みそかつ侍 for Expert, 緑風 犬三郎 for Master, サファ太 for Re:Master), each bringing their own interpretive flair to the song's frantic pace. The Re:Master chart sits at a demanding Lv13+ (13.8 constant) with 989 total notes, making it a significant technical challenge for advanced players. Beyond maimai, the song also crossed over into SEGA's CHUNITHM LUMINOUS rhythm game in February 2024.
