Overview

Brain Power is a high-energy electronic track by NOMA (ノマ), instantly recognizable for its infectious, vowel-heavy chant, "O-oooooooooo AAAAE-A-A-I-A-U-", that swept the internet as a viral meme in 2016. The song was originally created for KONAMI's SOUND VOLTEX II -infinite infection-, debuting in June 2013. When its surprise popularity led to licensing restrictions that prevented NOMA from authorizing use outside KONAMI's ecosystem, he made the rare decision to terminate his contract with KONAMI, resulting in the song's removal from SOUND VOLTEX and MUSECA on March 28, 2017, and freeing it for cross-platform distribution. Brain Power arrived in maimai on July 3, 2018, as part of the MiLK PLUS update, one of the first former SOUND VOLTEX-exclusive tracks to cross over, alongside 進め!イッスン軍団 -Rebellion of the Dwarfs-. Its maimai incarnation is layered with knowing nods to its KONAMI heritage: the MASTER chart's maximum theoretical score is 573,000, a direct wink at KONAMI's corporate code "573" (go-nana-san), and earning a FULL COMBO on EXPERT unlocks the title "mai騎士", a playful twist on "魔騎士" (maxi), the rank name for clearing SKILL ANALYZER Level.09 courses in SOUND VOLTEX. The EXPERT chart was designed by サファ太 (Safata) and the MASTER chart by 小鳥遊さん (Takanashi-san). At level 13 with a constant of 13.4, the MASTER chart packs 663 notes into the song's brisk duration, demanding precise stamina and pattern recognition from players.

Trivia

  • Brain Power was one of the first songs created for the SOUND VOLTEX series to later appear in maimai, alongside 進め!イッスン軍団 -Rebellion of the Dwarfs- in the same MiLK PLUS update.
  • NOMA canceled his contract with KONAMI to allow broader licensing of Brain Power. The track was removed from SOUND VOLTEX and MUSECA on March 28, 2017, and the contract officially ended on March 31, 2017.
  • The song's viral "O-oooooooooo" lyrics became a widespread internet meme in 2016. During streams, chat rooms would flood with the lyrics, with the chorus section seeing the most activity.
  • The MASTER chart's maximum theoretical score of 573,000 references KONAMI's company code "573" (go-nana-san), a recurring Easter egg in KONAMI games.
  • The FULL COMBO title "mai騎士" on EXPERT is a pun on "魔騎士" (maxi), the SKILL ANALYZER Level.09 rank in SOUND VOLTEX.
  • Brain Power's maimai release followed its removal from KONAMI's games by roughly 15 months, making it a notable test case for former KONAMI-exclusive content appearing in competitor cabinets.
  • The maimai version uses the original SOUND VOLTEX cut (1:52), while the CHUNITHM version uses a longer short edit of the extended album version (2:16).
  • Multiple official remixes exist, including Brain Power (Cranky Remix) and a full remix album HEADLINER's -REMIXES OF BRAIN POWER- featuring t+pazolite, USAO, REDALiCE, MYUKKE., TAG, NAOKI, Frums, and others.
  • Brain Power appears in over a dozen other rhythm games including CHUNITHM, ONGEKI, Cytus II, Muse Dash, WACCA, GROOVE COASTER, PUMP IT UP XX, Lanota, and Taiko no Tatsujin.
  • The MASTER chart has undergone level adjustments across maimai versions: it launched at 12+ in MiLK PLUS, was lowered to 12 in FiNALE, and has since settled at 13 from Splash onward.
