Overview

隠密あんみつDX (Onmitsu Anmitsu DX) is a comedic ninja-rock original song commissioned for maimai DX FESTiVAL PLUS, composed by Carlos Hakamada (also known as Saize P, the creator of the equally playful maimai track ちがう!!!). Featuring dual vocals by Mei Hinami and Yui Furukawa, the track runs at a brisk 155 BPM and is officially classified under the in-game genre "糖質無制限ニンジャロック" (Sugar-unlimited Ninja Rock), a tongue-in-cheek label that perfectly captures its premise: a squad of ninjas abandoning their covert missions to satisfy their cravings for anmitsu, a traditional Japanese sweet made from agar jelly, red bean paste, and fruit. The lyrics narrate a stealthy nighttime escape, a dash to a beloved dessert shop, and the hilarious obstacles that stand between the ninjas and their sugary goal. The jacket and music video were produced by Taiyo Yamamoto, Radiosity, and えーれ. Originally tied to the Dragon Area 2 event as a 100 km distance reward in FESTiVAL PLUS, the song became universally unlocked by default starting with maimai DX BUDDiES PLUS and is now available across all regions including Japan, international, USA, and China.

Trivia

  • The song's in-game genre is officially listed as 「糖質無制限ニンジャロック」 (Sugar-unlimited Ninja Rock). This label was made available as a circle-point reward item from February 2026.
  • Carlos Hakamada (カルロス袴田), the composer, also produces under the alias Saize P (サイゼP) and previously contributed ちがう!!! to the maimai song library.
  • The song was originally unlocked in Dragon Area 2 (ドラゴンちほー2) by accumulating 100 km of distance traveled in the area's progression system. It became available by default starting with maimai DX BUDDiES PLUS.
  • The UTAGE (宴) chart, titled 「餡」 (An, referring to the sweet red bean paste used in anmitsu), was added in maimai DX CiRCLE on September 19, 2025. With 278 Break notes out of 740 total, it is an extremely Break-heavy gimmick chart.
  • The UTAGE chart's designer description reads: 「いい感じに同時押しするといい感じになる!」, meaning 'If you do simultaneous presses nicely, it'll feel nice!' This is a direct nod to the 'anmitsu' technique from beatmania, where notes are intentionally hit slightly early or late as chords to simplify complex patterns.
  • The music video was created by Taiyo Yamamoto (山本太陽), Radiosity, and えーれ.
  • The song has a duration of 2:08.
  • The lyrics follow a narrative arc: ninjas sneak through a nightscape under a hazy moon, rush to an anmitsu shop, face a sudden closure due to the elderly owner's financial troubles, and eventually help turn the shop around, all while repeating the refrain '忍者!なんじゃ!隠密なミッション / あんみつ食べたい!' (Ninja! What! A secret mission / I want to eat anmitsu!).
  • The title is a layered pun: 隠密 (onmitsu, 'secret agent' or 'ninja') combined with あんみつ (anmitsu, a dessert) and DX (deluxe), effectively reading as 'Secret Agent Anmitsu Deluxe.'
  • The MASTER chart (level 13, constant 13.5) was designed by はっぴー (Happy), while the EXPERT chart (level 10+) was designed by サファ太 (Safata).
