ガチャガチャきゅ～と・ふぃぎゅ@メイト (romanised as Gacha Gacha Cute Figu@mate in Asian English releases) is a denpa song by the Japanese sound unit MOSAIC.WAV, the duo of composer/arranger Susumu Kayamori (柏森進) and vocalist MI-KO (み～こ). Originally produced as the opening theme for the 2006 adult visual novel ふぃぎゅ@メイト (Figu@Mate), the track quickly outgrew its source material and became part of the early Nico Nico Douga otaku music canon alongside contemporaries such as レッツゴー！陰陽師 and true my heart. The song made its rhythm-game debut in CHUNITHM STAR on September 21, 2017, before entering the maimai series on March 22, 2019 as part of maimai FiNALE, the final arcade version preceding the DX rebranding. The maimai version uses a shorter edit (2:05) compared to the CHUNITHM cut (2:29). In maimai, the Master chart was designed by 玉子豆腐 (Tamagodoufu) at level 13 and is characterised by dense Slide and Break note patterns that test a player's reading and stamina, while the Expert chart by サファ太 (Safata) offers a level-11 warm-up. Both charts have undergone level revisions across successive DX updates as SEGA recalibrated the series' difficulty curve. ガチャガチャきゅ～と・ふぃぎゅ@メイト was removed from Asian English maimai cabinets starting with the first maimai DX release, remaining available only in Japan. A 15th-anniversary variations album, ガチャガチャきゅ〜と・ふぃぎゅ@変奏曲[ヴァリエーション]〜Figu@15th Anniv.〜, was later released to celebrate the track's enduring legacy.
