MOON NIGHTのせいにして (MOON NIGHT no sei ni shite) is a vocal track by the unit DRAMATIC STARS from THE IDOLM@STER SideM, Bandai Namco's male-idol spinoff of the long-running THE IDOLM@STER franchise. The unit comprises three characters, Teru Tendou (CV: Shuugo Nakamura), Kaoru Sakuraba (CV: Yuuma Uchida), and Tsubasa Kashiwagi (CV: Taku Yashiro), each voiced by established seiyuu who perform their own character's lines in the song. The track was composed by Yuuki Honda and arranged by Takuya Sakai, both of Arte Refact, with lyrics penned by Aira Yuuki. It originally appeared on THE IDOLM@STER SideM 2nd ANNIVERSARY DISC 01 DRAMATIC STARS & High×Joker, released in 2016. In maimai, MOON NIGHTのせいにして debuted as part of the initial lineup for maimai でらっくす UNiVERSE on September 16, 2021, in Japanese and Asian arcade editions, later arriving on the Chinese-region 舞萌DX 2022 on December 16, 2022. The song features a brisk 141 BPM pop arrangement characteristic of the SideM franchise's brighter idol numbers. Its MASTER chart (level 12, designed by はっぴー) leans heavily on Slide notes, 95 out of 568 total notes, giving the chart a flowing, melodic feel that complements the song's upbeat chorus sections. The EXPERT chart (level 8, designed by 隅田川星人) takes a more balanced approach across note types. The track was removed from Chinese arcade editions with the arrival of 舞萌DX 2024 on September 4, 2024, and from Asian-region cabinets in maimai DX BUDDiES PLUS on September 13, 2024, making it a legacy song no longer available on current arcade hardware.
