ミラクルペイント (Miracle Paint) is a VOCALOID song by OSTER project featuring Hatsune Miku, originally uploaded to NicoNicoDouga in 2008. It was included on OSTER project's debut album みくのかんづめ (Miku no Kandzume, 2008) and quickly became one of the composer's signature tracks, appearing across multiple Sega rhythm game franchises. The song was added to maimai MiLK PLUS on August 21, 2018, under the niconico & VOCALOID category. At 215 BPM, the track is driven by an upbeat shuffle rhythm, a swing feel that gives it a distinctive bounce. Its MASTER chart (level 13, designed by 某S氏) directly interprets the song's lyrical imagery: the slide patterns trace magic-circle brushstrokes that mirror the phrase "魔法の一筆" (a single stroke of magic) from the chorus. The first and second iterations of the chorus flip the slide layout left-to-right, creating a mirrored challenge that occasionally forces arm crosses when maintaining a simultaneous hold note. The EXPERT chart (level 10+, designed by はっぴー) shares the same rhythmic foundation at a lower density. The in-game background video originates from Hatsune Miku: Project DIVA Arcade, based on the PV first seen in Project DIVA 2nd on PSP. The song later appeared in Project DIVA F2nd with a branching PV that alters the performance animation depending on player inputs. ミラクルペイント was removed from the Asian and Chinese versions of maimai starting with the first maimai DX, restricting its availability to the Japanese version. Outside of maimai, OSTER project released a remix by Plus-Tech Squeeze Box titled ミラクルペイント (PSB REMIX) on the album Recursive Call, and published a 10th-anniversary sequel, ミラクルショウタイム (Miracle Showtime), in 2018.
