Lividi is an original maimai composition by Feryquitous, a composer affiliated with the Diverse System label. The track stands out for being performed entirely by the composer himself, Feryquitous handles composition, arrangement, lyrics, and vocals. The lyrics are written in a constructed fictional language, accompanied by a Japanese translation that touches on themes of obsession,颠覆ing rules, and clinging to fixed values. Released on March 28, 2017, Lividi debuted as the fourth Challenge Track in maimai MURASAKi, available only during a limited preview period until April 9 before entering the general rotation. Its music video was created by the artist レク (Reku), the same visual collaborator behind AcuticNotes' Axeria, and the two songs share more than just a production tag. The MASTER chart, designed by Moon Strix, deliberately carries forward the difficult key-change (転調) sections that made Axeria's chart notorious, creating a spiritual sequel for players who mastered that earlier gauntlet. The EXPERT chart was designed by Jack. With a relentless 191 BPM pulse, Lividi is characterized by aggressive synth leads, driving percussion, and a brooding atmosphere that matches its lyrical darkness. Over the course of maimai's version history, its chart levels have been re-evaluated multiple times, the Advanced chart rose from 8+ to 9+, Expert climbed from 10+ to 13, and Master escalated from 12+ to 14, reflecting both the game's evolving difficulty standards and the chart's enduring challenge. The song also appears in the Splash PLUS 十段 (10th Dan) course alongside other demanding tracks.
