Overview
＋♂ (pronounced "Plus Danshi," ぷらすだんし) is a niconico & VOCALOID track originally created for the cosplay dance group ARSMAGNA, with music composed and arranged by Giga and lyrics penned by Reol, a duo well known in the Vocaloid producer scene for their energetic, pop-leaning productions. The song features Kagamine Len as the lead vocalist, supported by a chorus of Miku Hatsune, Rin Kagamine, Luka Megurine, and GUMI, giving it an unusually rich Vocaloid ensemble for a single maimai track. It first appeared on the 2014 compilation album EXIT TUNES PRESENTS Vocalospace feat. 初音ミク before joining maimai as part of the PiNK edition's launch lineup on December 9, 2015.
The title plays on the male symbol (♂), reading as "Plus Danshi", a lighthearted reference to boys and adolescent energy. Its lyrics follow a breathless schoolboy crush, layering math-class metaphors like "因数分解" (factorization) and rapid-fire wordplay over a driving 180 BPM beat. Rather than an animated music video, the in-game visuals use ARSMAGNA's own choreography footage, directly tying the track to its real-world dance performance roots. Over subsequent maimai versions, the chart levels for ＋♂ were revised multiple times as the game's difficulty standards evolved, the Master chart in particular rose from an initial 11+ to its current 13. The MASTER chart, designed by はっぴー, stands out for its dense Slide-note count (144), while Jack's EXPERT chart offers a demanding 10+ experience that has been a staple for intermediate players since the PiNK era.
