東方スイーツ！～鬼畜姉妹と受難メイド～ (Touhou Sweets! ~Cruel Sisters and the Suffering Maid~) is a denpa-style electro-pop arrangement by the Touhou doujin circle Innocent Key, featuring three vocalists who each voice a member of the Scarlet Devil Mansion cast. The song draws from two iconic themes from 東方紅魔郷 (Touhou Koumakyou / Embodiment of Scarlet Devil), Remilia Scarlet's "Septette for the Dead Princess" (亡き王女の為のセプテット) and Flandre Scarlet's "U.N. Owen Was Her?" (U.N.オーエンは彼女なのか？), weaving them into a fast-paced, playful track at 179 BPM. A recurring lyrical refrain of "メイド！ニーソ！PAD長！" (Maid! Nylons! PAD-chō!) became a memorable hook among Touhou fans, riffing on Sakuya Izayoi's signature look and the long-running fandom nickname "PAD長", a joking reference to her platform boots. 小宮真央 (Komiya Mao) handles Remilia's vocals, ココ (Coco) takes on Flandre, and 樹詩音 (Shion Jyu) sings as Sakuya, giving each character a distinct voice in the back-and-forth dialogue-style arrangement. Added to maimai during the ORANGE PLUS edition on July 16, 2015, the song received four standard charts. The Master difficulty (Lv13, constant 13.2) was designed by rioN, a prolific maimai charter known for technically demanding patterns, while the Expert chart (Lv10+, constant 10.6) was crafted by 某S氏.
