Oshama Scramble! is a high-octane instrumental hardcore track by t+pazolite (Tomoyuki Hamada), one of the most recognizable names in Japanese doujin and rhythm-game music. The song debuted in maimai ORANGE PLUS on June 25, 2015, but its origins trace back to SEGA's HALFPIPE TOKYO attraction at Joypolis, an indoor theme park experience that served as the creative springboard for what would become one of the most ported tracks in the SEGA rhythm game universe. The title draws from the Japanese word "oshama" (おしゃま), describing a child who speaks or acts precociously like an adult, typically said of girls. This playful concept is brought to life in the music video by 百舌谷 (Mozuya), which follows the antics of two cats, the black Shama and the white Milk, named by chart designer Jack himself. Musically, the track is pure t+pazolite: a relentless 190 BPM barrage of stuttering synth leads, breakbeat-inflected percussion, and melodic hooks that have made it a favorite among high-level players. Beyond maimai, Oshama Scramble! was among the first original songs to appear across all three of SEGA's arcade rhythm game pillars, maimai, CHUNITHM, and オンゲキ, cementing its status as a franchise-wide signature piece. It has since been licensed to Cytus II, Arcaea, Muse Dash, GROOVE COASTER, and 太鼓の達人, and even appears as in-game music in Like a Dragon: Pirate Yakuza in Hawaii. The Standard Master chart, designed by Jack, is a punishing arrangement of exactly 1,111 notes with zero Hold inputs, an all-Tap/Slide/Break composition that has become a rite of passage for advanced players.
