Overview

Little "Sister" Bitch is a blistering happy-hardcore arrangement of U.N. Owen Was Her? (U.N.オーエンは彼女なのか？), the extra-stage boss theme of Flandre Scarlet from 東方紅魔郷〜 the Embodiment of Scarlet Devil. The track was produced by t+pazolite (Tomoyuki Hamada), a prolific doujin and rhythm-game composer whose high-BPM, aggressively cheerful sound has made him a fixture across arcade music games. Originally submitted to THE BMS OF FIGHTERS 2005, where it placed 26th overall, the track later appeared on the compilation album t&T. (tpz And TOUHOU.) and eventually crossed over into maimai DX as part of the 東方Projectちほー (Touhou Project Area) event in November 2019. Its maimai incarnation features a notoriously punishing 13+ MASTER chart (designed by チャン@DP皆伝) that demands rapid alternating-tap patterns, dense slide sequences, and acute spatial awareness across the full DX touch panel. The EXPERT chart, handled by 華火職人, underwent a minor revision shortly after the song's general unlock in January 2020. Little "Sister" Bitch went on to appear in SEGA's CHUNITHM NEW as well, and a spiritual sequel, Electric "Sister" Bitch, was released for KONAMI's SOUND VOLTEX.
