サイエンス (Science) is a VOCALOID original song by producer MIMI, featuring the SV voicebank of Teto Kasane (重音テトSV). Released as a single/album in 2024, the track was added to maimai でらっくす CiRCLE at the version's launch on September 18, 2025, appearing across Japanese, international, and US arcade regions. The lyrics weave scientific vocabulary, experiments, flasks, reactions, theorems, into a deeply personal narrative about loneliness, the search for meaning, and the desire to find one's "proof of existence" (存在証明). The music video, produced by 3774., depicts choreographed hand and body movements that directly influenced the EXPERT chart design. Designer はっぴー placed notes to mirror these MV motions at specific lyrical moments, such as the inward slide gesture during "今日も探すよ" and the head-tilt-like slide movements during "サイエンスみたいに." At the song's final "サイエンス," the hold and touch note positions are deliberately aligned with the hand positions seen in the video. The Master chart, designed by サファ太 at level 13.0 with 750 notes, presents a high-density arrangement with demanding slide patterns that test endurance and precision.
