Jump!! Jump!! Jump!! is the upbeat main theme of ONGEKI PLUS, the expanded arcade release of Sega's ONGEKI rhythm game. Composed, arranged, and penned by Makoto Miyazaki (宮崎誠), the track is performed by the voice cast of five ONGEKI characters, Hikaru Akao as Hoshizaki Akari, Risa Kubota as Fujisawa Yuzu, Anzu Haruno as Misumi Aoi, Yurika Kubo as Takase Rio, and Naomi Ohzora as Ousaka Akane, credited collectively as オンゲキシューターズ (ONGEKI Shooters). Unlike the main unit ASTERISM, オンゲキシューターズ is a flexible label that changes lineup per track; here it brings together all five heroines featured on the song's jacket art. The song arrived in maimai でらっくす on July 26, 2019, as part of a cross-title celebration marking ONGEKI's first anniversary. Alongside STARTLINER, it was one of the first two ONGEKI PLUS songs ported to maimai, laying the groundwork for the ongoing オンゲキ＆CHUNITHM category. Its MASTER chart (level 12, constant 12.0), designed by ロシェ@ペンギン, features a dense 574-note layout with prominent Slide and Touch patterns, while the EXPERT chart by サファ太 balances 480 notes across all five note types. The track's difficulty has been adjusted across several maimai versions, the MASTER level oscillated between 11+ and 12, and the BASIC level settled from an initial 4 to 3, reflecting how its place in the tier list evolved as the DX scoring system matured.
