Overview

∀ (read as the universal quantifier symbol) is a high-energy BMS-origin track by the artist ああああ (aaaa), first introduced to audiences through BOFXVII, the 17th iteration of the BMS of Fighters competition. The song was later brought into the maimai arcade rhythm game series as part of the DX PRiSM PLUS update on August 1, 2025, under the ゲーム&バラエティ (Game & Variety) category. Clocking in at a brisk 245 BPM, the track pairs its relentless tempo with a distinctive visual identity: the title is rendered solely as the mathematical for-all symbol ∀, and the jacket art and BGA carry a cryptic, abstract aesthetic. In maimai, the song features DX-style charts across four difficulties. The Expert chart (Lv 11+, constant 11.6) was designed by Luxizhel, while the Master chart (Lv 14, constant 14.3) was crafted by サファ太 (Safata). The Master chart's 670 total notes include a notably high count of Slide (56) and Touch (49) notes for its level, reflecting the PRiSM-era design philosophy of integrating touch-screen patterns with traditional rhythm-game inputs.
