All songs

Overview

オリフィス (Orifice) is a maimai original song from the Splash era, produced by veteran Vocaloid composer 40mP and performed by シャノ (Chano). The title's literal meaning, a small aperture used in fluid measurement, contrasts sharply with the song's emotional core, which centers on grief and the desire to rewind time. An in-game flavor text introduces Nanoha, a character who gains time-leap abilities after a car accident takes his childhood friend, leaving him in a world only he recognizes as incomplete. The lyrics reinforce this theme through the recurring image of an hourglass (砂時計), with sand falling in both directions as the protagonist struggles against an unalterable past. Musically, the track drives forward at 200 BPM with a bright yet bittersweet electronic-rock arrangement, balancing 40mP's melodic pop instincts with a lean toward urgent, high-energy production. 40mP and Chano had previously built a collaborative catalog on Sega's CHUNITHM, including 夕暮れワンルーム, 時の冒険者, and 朝焼けプラットホーム, making オリフィス their first song to appear in maimai. The accompanying music video was produced by the circle 群青リコリス (Gunjou licorice). In maimai DX, オリフィス was initially locked behind a travel-progress condition in the Sky Street Area (スカイストリートちほー), requiring 154 km of cumulative distance during Splash. It became available by default from UNiVERSE onward. The Master chart, designed by はっぴー, originally sat at level 13 through UNiVERSE before being revised to 12+ starting with BUDDiES+. The Expert chart was designed by 華火職人 (Kanon Oguni).

Trivia

The Japanese word オリフィス is a loanword from English "orifice," referring to a small hole in a thin plate used for measuring fluid flow in engineering contexts, a clinical term that contrasts with the song's deeply emotional theme of loss and time manipulation.
40mP (40meterP) is best known as a Vocaloid producer who has contributed numerous songs to the Hatsune Miku ecosystem, as well as original compositions for Sega's rhythm game series including CHUNITHM and maimai.
シャノ (Chano) and 40mP had previously collaborated on multiple CHUNITHM songs, 夕暮れワンルーム, 時の冒険者, and 朝焼けプラットホーム, before bringing オリフィス to maimai as their first cross-series contribution.
The music video was created by the doujin circle 群青リコリス (Gunjou licorice), who have produced visual content for several Sega rhythm game songs.
In the Chinese version of maimai (舞萌DX), オリフィス was unlockable by reaching 400 m of progress in the corresponding area, compared to the 154 km requirement in the Japanese and international versions.
The Master chart's level has been adjusted twice: originally level 13 in Splash through UNiVERSE, it remained 13 through UNiVERSE+ and BUDDiES, then was lowered to 12+ starting with BUDDiES+.
The Basic chart also saw a level change: originally level 4 in Splash through UNiVERSE, it was lowered to level 3 from UNiVERSE+ onward.
The lyrics center on an hourglass (砂時計) metaphor, with lines describing sand that falls from past to present while the narrator tries in vain to reverse it, echoing the time-loop premise established in the flavor text.
The song runs 2 minutes and 22 seconds, a compact length that fits its high-energy, 200 BPM tempo.
Unlike many maimai originals that later appear in other Sega rhythm games, オリフィス has not appeared in any other music game as of its latest update.
