Overview
M.S.S.Planet is the title track from M.S.S Project's debut self-published doujin album, released on July 7, 2013. The song is a Vocaloid duet between Hatsune Miku and GUMI, with composition by FB777 (the group's founder) and arrangement and guitar work by KIKKUN-MK-II. Its lyrics weave a vivid sci-fi fantasy narrative touching on themes of destiny, chaos, fallen angels, and cosmic phenomena such as Ragnarok, Eclipse, and the Big Bang, a style that fans often describe as carrying a chuunibyou (delusional middle-school) flavor. The music video was produced by the creator ぼうし屋 (Boushiya).
The track was added to maimai as part of the GreeN PLUS update on March 20, 2014, initially available only with Standard charts under the niconico genre (later re-categorized as niconico & VOCALOID). Nearly eight and a half years later, it received a full set of DX charts (Basic through Master) in maimai でらっくす FESTiVAL on September 15, 2022, originally unlockable via Stamp Card and made available by default from the BUDDiES version onward. The song also crossed over into SEGA's CHUNITHM series, appearing at that game's launch and eventually receiving an extravagant WORLD'S END chart. Within maimai, M.S.S.Planet is notable for having its Standard and DX Master charts handled by different designers, mai-Star and はっぴー respectively, giving players two distinctly flavored top-end interpretations of the same composition.

Trivia
- M.S.S.Planet was the title track of M.S.S Project's debut doujin album, released on July 7, 2013, a date that coincides with Tanabata, the Star Festival in Japan.
- The song features dual Vocaloid vocalists: Hatsune Miku (初音ミク) and GUMI (Megpoid), a relatively uncommon pairing for a single niconico-originated track at the time.
- The music video (movie) was produced by the creator ぼうし屋 (Boushiya).
- Within maimai, the Standard Master chart and the DX Master chart were designed by different note designers, mai-Star and はっぴー (Happy) respectively, resulting in two distinct high-difficulty interpretations of the same song.
- The DX Master chart debuted at Level 13 in FESTiVAL, making it one of the hardest charts in the game at that moment, before being revised down to Level 12+ (constant 12.9) from FESTiVAL PLUS onward.
- The Standard Expert chart has undergone significant level inflation over the game's lifespan: it started at Level 9 in GreeN PLUS, climbed to 9+ in でらっくす PLUS, and reached 10+ by UNiVERSE PLUS, reflecting the gradual upward recalibration of maimai's difficulty scale.
- The Standard Master chart was originally Level 10 at launch, then rose through 10+ (PiNK), 11 (MURASAKi), 11+ (でらっくす PLUS), 12 (Splash through FESTiVAL), and finally 12+ from BUDDiES PLUS onward.
- The lyrics build toward a climactic four-line sequence invoking Norse and cosmic mythology: 「最強プラネット ラグナロク / 極限プラネット エクリプス / 終焉プラネット ビッグバン / MSプラネット カオスアンサー」 (Strongest Planet Ragnarok / Ultimate Planet Eclipse / Final Planet Big Bang / MS Planet Chaos Answer).
- The song is 2 minutes and 2 seconds in length.
- In SEGA's CHUNITHM, M.S.S.Planet received a WORLD'S END chart (difficulty 割☆3) designed by 'M.S.S.Split', a charter alias that appears to be a wordplay on the group's name, containing 4,546 notes, one of the highest note counts in the game.
- The DX charts were added nearly 8.5 years after the original Standard charts, making M.S.S.Planet one of the older songs in the maimai catalog to receive a full DX chart refresh.
