しゅわスパ大作戦☆ is a high-energy Touhou Project arrangement by the prolific doujin circle SOUND HOLIC, fronted by vocalist Nana Takahashi who also wrote the lyrics and arranged the track. The song remixes the staff roll theme from 東方萃夢想 (Touhou Suimusou / Immaterial and Missing Power), the collaborative fighting game developed by Team Shanghai Alice and Tasogare Frontier. First released on SOUND HOLIC's 2009 album 想 -OMOI-, the track was composed by U2 with guitar work by Josh and a music video by 月見堂. The title playfully combines the onomatopoeic "shuwa" (the fizz of carbonation) with "supa" (spark) and "daisakusen" (great operation or battle plan), mirroring the lyrics' flirtatious, cocktail-mixing pursuit of love punctuated by shouted calls of "いっき♪" (bottoms up!). The song's bubbly, effervescent production contrasts cleverly with the bullet-hell danmaku imagery of its source franchise. In maimai, しゅわスパ大作戦☆ debuted on October 3, 2013, as part of the GreeN update and has since become one of the earlier Touhou crossovers in the series. Its MASTER chart, designed by 某S氏, currently sits at Lv. 12+ and is recognized for dense slide patterns that test a player's spatial awareness and cross-hand coordination. The chart has been re-rated multiple times across versions, originally Lv. 10 in GreeN, it climbed steadily through Lv. 11, 11+, and 12 before settling at its current rating. The EXPERT chart by mai-Star offers a Lv. 9+ challenge with a strong focus on slide note execution. An UTAGE (banquet) chart at difficulty 星/13?, designed by ☆TAP大作戦☆, was added during MURASAKi PLUS and later revived in BUDDiES, extending the song's replayability for high-end players.
