Overview
ARROW is a VOCALOID track by producer niki, sung by the voice synthesizer Lily. Originally posted to niconico, the song arrived in maimai with the MURASAKi PLUS update on July 25, 2017, joining the game's niconico & VOCALOID lineup. niki handled the composition, arrangement, and lyrics himself, and also produced the accompanying music video, a hallmark of his solo production approach. The song's mid-tempo electronic pop arrangement at 131 BPM, paired with Lily's clear vocal delivery, creates a polished and emotive soundscape. Lyrically, ARROW uses the metaphor of a piercing arrow to evoke feelings of emotional exposure and longing, with lines like "僕の心に突き刺さるARROW" (the arrow piercing my heart) driving the theme home. The track later appeared on niki's album WAVE, released in 2019. Among rhythm game appearances, ARROW is exclusive to maimai. Its charts have undergone several difficulty adjustments across DX versions: the EXPERT chart rose from level 10 at launch to its current 12, the MASTER chart climbed from 12 to 13, and the ADVANCED chart was later bumped from 6 to 7+, adjustments that reflect maimai's expanding difficulty scale over successive editions.
