Overview
あねぺったん is a Touhou Project arrange cover performed by the Tsukisuzu Sisters (月鈴姉妹), the sister duo within SEGA's original fictional band project Irodorimidor (イロドリミドリ). The song is a playful rearrangement of Silver Forest's iconic doujin track つるぺったん, which itself reimagines the final boss theme "竹取飛翔 〜 Lunatic Princess" from *Touhou 永夜抄 〜 Imperishable Night* (original composition by ZUN). The arrangement was handled by NYO (Silver Forest) and D.watt (IOSYS), with lyrics by bit, Dencyu, and Lettuce Shichijou, and vocals by Nachi Tsukisuzu (CV: Ayaka Imamura) and Shirona Tsukisuzu (CV: Marika Kōno).
The title あねぺったん is a portmanteau, combining *ane* (お姉ちゃん, "older sister," a reference to the elder Tsukisuzu sister Nachi) with *pettan* from the original つるぺったん. The song made its rhythm-game debut not in maimai but in CHUNITHM AIR PLUS as an April Fools 2017 WORLD'S END chart before receiving standard charts in that game later that year. It crossed over to maimai on October 16, 2018 as part of the MiLK PLUS update, where it was categorized under the オンゲキ＆CHUNITHM genre, a cross-title collaboration category spanning SEGA's three arcade rhythm games. Its chart levels have been adjusted upward over successive maimai DX versions, and it remains available across all regions (JP, INTL, USA, CN).
