Overview

It was made generally available on January 9, 2026. The track showcases Chikara's dense, poetic lyricism, the title itself is a portmanteau of 流浪 (rurou, wandering) and 襤褸 (ranru, tattered rags), evoking the image of a drifting, broken soul. Sung by CeVIO AI voicebanks Teto Kasane (重音テト) and Moca Miyamai (宮舞モカ) with an unusually large chorus cast including GUMI, Seika Kyomachi, Ryo, Jin, Frimomen, and Ryuusei Aoyama, the song layers rapid wordplay, rhetorical questions, and dark, theatrical imagery over a driving 156 BPM production. The music video was created by 翌明ネガ. Chikara debuted as a Vocaloid producer in April 2021 with "Untitled Document" (無題のドキュメント) and Rurouranru represents his first maimai commission. The MASTER chart, designed by るしえる (Luxizhel) at level 14 (constant 14.3), and the EXPERT chart by はっぴー (Happy) at level 11+ (constant 11.6), give players demanding note-density to match the song's frenetic pace.

Trivia

Rurouranru was one of the winners of the maimai DX Award at FEAT CONTEST 2024, a SEGA contest soliciting original song submissions for inclusion in maimai.
Composer Chikara (ちから) debuted as a Vocaloid producer in April 2021 with the song 'Untitled Document' (無題のドキュメント). Rurouranru is his first maimai commission.
The song features an unusually large chorus of six additional vocalists: GUMI, Seika Kyomachi, Ryo, Jin, Frimomen, and Ryuusei Aoyama, layered beneath the lead vocals by Teto Kasane and Moca Miyamai.
The title 'るろうらんる' is a portmanteau of 流浪 (rurou, wandering/roaming) and 襤褸 (ranru, tattered/ragged), visualized in the lyrics as a wandering broken figure. The Japanese wiki playfully notes it is 'definitely not ranranru'.
Rurouranru is the first niconico & VOCALOID genre song to appear as a Perfect Challenge in the maimai DX era, and the second overall life-based unlock for the genre since 幸せになれる隠しコマンドがあるらしい in maimai MURASAKi PLUS, a gap of roughly 7 years and 10 months.
The lyrics contain the line 「恥を知れ」(shame on you) answered by 「あい！」(aye/yes!), which also appear as in-game称号 (title/achievement) names. The title '恥を知れ' unlocks by getting 1 MISS on the song, and 'あい！' unlocks by playing the song together with someone wearing '恥を知れ'.
The MASTER chart at level 14 (constant 14.3) was designed by るしえる (Luxizhel), while the EXPERT chart at level 11+ (constant 11.6) was designed by はっぴー (Happy).
In the Asian version, Rurouranru became unlockable from February 13, 2026, later than the Japanese release.
The song's BPM is a steady 156, with no tempo changes, and runs 2 minutes and 4 seconds in length.
