Overview
無敵We are one!! is an upbeat, high-energy crossover track that originated in Sega's CHUNITHM rhythm game series before landing in maimai PiNK PLUS at that version's launch on June 30, 2016. Performed by the fictional five-member vocal group Irodorimidori (イロドリミドリ), the song was composed, arranged, and written by y0c1e (Ryohei Sataka) of Hifumi,inc., a producer known for contributing lively, character-driven songs across Sega's rhythm game ecosystem. Clocking in at 190 BPM with a runtime of roughly 2 minutes 21 seconds, the track's lyrics champion togetherness and resilience ("Muteki desho We are one!!", "We're invincible, We are one!!"), matching the cheerful, can-do energy Irodorimidori's fictional band persona embodies. The music video was produced by yama_ko and まりオイル. Within maimai, the song has lived through an unusually long revision history: its chart levels were adjusted across nearly every major version from PiNK PLUS through BUDDiES+, as the game's difficulty scaling evolved. The Master chart (level 13+, constant 13.7) by Techno Kitchen stands out for its dense Slide-note layout, 143 Slides out of 938 total notes, while the Expert chart (level 10) was designed by ロシェ@ペンギン. In Asian English releases of maimai, the title is localized as "MUTEKI We are one!!" and the artist as "IRODORIMIDORI."
