Club Ibuki in Break All is a Touhou Project arrange track produced by the IOSYS doujin circle, built around two themes from the fighting game 東方萃夢想 (Immaterial and Missing Power): the Hakurei Shrine feast stage theme Demystify Feast and Suika Ibuki's boss theme 御伽の国の鬼が島 ～ Missing Power. The arrangement is by void (Yuuya Kobayashi), with lyrics by Yoshimi Youno (Takafumi Suzuki) and vocals by Marina Fujiwara. It originally appeared on IOSYS's 2009 Comiket album 東方年柄年中 (Touhou Nenjuu Nenjuu), and the jacket art used in maimai is taken directly from that album release. The song takes a playful, self-aware premise: Suika Ibuki, the oni of size-altering power, is recast as the boisterous proprietress of a host club. The lyrics, laden with call-and-response shouts, fourth-wall breaks, and rapid-fire lines like "福はウチ！鬼もウチ！酒もウチ！" (Good fortune is ours! Oni are ours! Sake is ours!), lean into the character comedy that became a defining IOSYS hallmark in the late 2000s Touhou arrange scene. The animated music video by ノヤマコト (Noyamakoto) amplifies the track's chaotic energy with vibrant, fast-paced visuals. In maimai, the song has seen its chart levels revised upward across multiple version updates, with the Master chart rising from 11+ in the original MURASAKi release to 13 in later editions.
