UTAKATA is a character song for Kaede Kujou (九條 楓), a member of the in-unit R.B.P. from Sega's rhythm game ONGEKI. Composed by yuyoyuppe (Takehiro Mamiya), a prominent doujin music producer known for blending metal, electronic, and vocaloid-driven production, the track originally appeared in ONGEKI PLUS in June 2019 before being ported to maimai でらっくす PLUS in February 2020 under the cross-game ONGEKI & CHUNITHM genre category. The title "UTAKATA" (うたかた) translates to "bubbles" or "foam" in Japanese, a word often used poetically to evoke ephemerality and fleeting beauty, fitting for a character song themed around transience and emotional intensity. The track's driving BPM of 185 and yuyoyuppe's signature fusion of aggressive synth riffs and pop-accessible melody lines give it a distinctive energy that carries across all five maimai DX note types. In maimai, the Master chart, designed by シチミヘルツ (Shichimi hertz) at level 12+ (constant 12.6), features a notably high Slide-note density (93 slides out of 680 total notes), creating a flashy, flowing pattern that mirrors the song's ephemeral title. The Expert chart was designed by KTM (Kiyotaka Sasa). The Master difficulty underwent an unusual level revision over the game's version history: it launched at 12+, was lowered to 12 during the Splash through BUDDiES era, and restored to 12+ from BUDDiES+ onward. An extended version and an instrumental version of UTAKATA appear on the ONGEKI Vocal Collection 05 soundtrack.
