Overview
右肩の蝶 (Butterfly on the Right Shoulder) is a Vocaloid original track by のりP (NoriP), a producer active in the Vocaloid doujin music community. The song exists in two distinct vocal arrangements: an original version sung by Kagamine Rin and a self-cover featuring Kagamine Len. The version included in maimai is the Kagamine Len self-cover, as shown on the in-game jacket art. Released on January 25, 2019, during the FiNALE era, the track falls under the niconico & Vocaloid genre and has remained exclusive to Japanese arcade cabinets. Over successive maimai DX version updates, from Splash through FESTiVAL, its chart levels have been revised as part of ongoing difficulty rebalancing. The Master chart, designed by ものくろっく, features a dense Slide-note layout (130 slides in 757 total notes) at a constant of 13.1, while the Expert chart was arranged by サファ太. The song's in-game achievements tie it to another track, 木彫り鯰と右肩ゾンビ, through shared keyword "右肩" (right shoulder) in their titles, requiring them to be played in the same credit.
