Overview
wowaka, one of the most influential Vocaloid producers of the late 2000s, broke into the scene with 裏表ラバーズ (Uraomote Lovers) in 2009, a song that immediately established his signature style: blistering tempos, dense almost-stream-of-consciousness lyrics, and a melodic core wrestling with emotional contradiction. The title translates roughly to "Inside-Outside Lovers," and the song's rapid-fire verses trade between sincerity and sarcasm, love and frustration, reflecting the duality its name suggests. Hatsune Miku's vocal is pushed to a breathless pace rarely heard in Vocaloid music at the time, making the track an instant landmark of the genre.
裏表ラバーズ joined the maimai arcade lineup on November 14, 2013, as part of the GreeN edition under the niconico & VOCALOID category. Its charts have aged alongside the game's difficulty curve: the Master chart, originally a level 11, climbed through multiple version updates to settle at 13+ (13.9 constant), reflecting both the series' recalibration and the chart's own demanding slide-and-tap structure. Expert (12+, 12.6 constant) was designed by 譜面-100号, a charter known for intricate, technical note placement, while the Master chart was handled by はっぴー (Happy), whose hallmark is dense Slide-note sequences, 82 Slides in a 651-note total. In the maimai でらっくす (DX) era, the song received a refreshed jacket based on its original artwork, and its animated music video was replaced with a static jacket image, aligning it with the DX series' presentation standards.

Trivia
- wowaka's breakout Vocaloid hit 裏表ラバーズ was uploaded to Nico Nico Douga in 2009 and rapidly became one of the defining songs of the early Vocaloid boom, helping cement his reputation alongside producers like kz (livetune) and ryo (supercell).
- The song's lyrics are built around the contrast between 表 (omote, outside/front) and 裏 (ura, inside/back), using the duality metaphor to explore the gap between performed emotion and genuine feeling in romantic relationships.
- In the maimai DX era (でらっくす onward), the jacket was updated to a new illustration based on the original key art, and the in-game background video was replaced with a static jacket image, a change applied to several early Vocaloid tracks during the transition.
- The maimai version runs 1:49, shorter than the full song (2:01 in CHUNITHM and オンゲキ), as is standard for arcade rhythm game cuts of Vocaloid tracks.
- The Master chart (designed by はっぴー) features 82 Slide notes out of 651 total, an unusually high Slide density for its era, foreshadowing the slide-heavy design philosophy that はっぴー would become known for in later maimai titles.
- The Expert chart, designed by 譜面-100号, has 42 Break notes out of 504 total, a higher Break ratio than the Master chart, giving it a distinct flavour as a Break-heavy technical challenge.
- 裏表ラバーズ' difficulty levels have been adjusted multiple times across versions: the Master chart began at level 11 in maimai GreeN, rose to 12 by MiLK, 13 by でらっくす PLUS, and finally 13+ from Splash onward, tracking maimai's expanding difficulty ceiling.
- The song also appears in SEGA's other rhythm games CHUNITHM (since 2016) and オンゲキ (since 2019), where it received multiple WORLD'S END and ULTIMA charts, making it one of the most cross-licensed wowaka tracks in the SEGA arcade ecosystem.
- 裏表ラバーズ was included on the compilation album EXIT TUNES PRESENTS Vocalolegend feat. 初音ミク (2010), alongside other early Vocaloid classics.
