Overview
メズマライザー (Mesmerizer) is a VOCALOID track by producer Satsuki (サツキ) that pairs the synthesized voices of Hatsune Miku and Kasane Teto over an energetic, J-pop-infused composition at 185 BPM. The song originally appeared on Satsuki's debut full album Circus's Detail (2024) before making its way into Sega's rhythm game ecosystem on March 13, 2025, launching simultaneously in maimai でらっくす PRiSM PLUS, CHUNITHM VERSE, and ONGEKI Re:Fresh.
The title is a transparent play on "mesmerize," and the lyrics lean into that conceit with hypnotic imagery and psychological wordplay. Lines like "あなた段々眠くなる" ("you're getting sleepy") and the recurring, pleading refrain "誰か、助けてね(^^♪" ("Someone, help me") weave a narrative of self-deception, societal exhaustion, and willing surrender to illusion. The song's official music video was produced by the artist channel, whose visual direction complements the hypnotic, slightly unnerving tone of the track.
In maimai, Mesmerizer is represented across all five DX difficulties, with the Re:Master chart (designed by サファ太 / Safata) standing out for its dense note count of exactly 1,000, a milestone number in rhythm-game charting, and a remarkably high 155 Break notes that test a player's precision under pressure. The Expert and Master charts were designed by ロシェ@ペンギン (Rocher@penguin) and 緑風 犬三郎 (Ryokufū Inusaburō) respectively. A cooperative "Buddy" utage (宴) chart was also added at launch, featuring asymmetrical left/right note distributions that require two players to work together.
