Momomomo Paradise is a Japanese idol group formed in 2021. Originally debuting as Gyakushyu Monster, the group was founded by Hicchyon and 2018 WACK AUDiTiON CAMP finalist Momonchi. The group was created through an audition held by Vocaloid P and former visual kei artist, Puku, and debuted as Gyakushyu Monster with a starting lineup of Momonchi, Hicchyon, Pipitan, Kotorin, Renren, and Mairu. Gyakushyu Monster released their first single "Papparapa Kakumei" in July 2021 followed by "WOLFMAN" the following week. However, due to multiple member departures, Gyakushyu Monster disbanded in October 2021, rebranding soon after as Momomomo Paradise, alongside new members Chiitan, Myucha, and Chinmaru Kun. The new group released their first digital singles "Music Box Medley" and "Momo × MomoParadise" in November 2021, followed by "Ichigo-chan" and "Kurukuru Parade" in March and August 2022, respectively. Their debut album Black Momopara BEST, featuring lead single "Gyakushyu Monster" was released on October 18, however their success was overshadowed by two further member graduations by the end of the year, seeing the group reduced to three members; Momonchi, Hicchyon, and Chiitan. On January 7, 2023, the trio released new single "Pegasus" on January 7, 2023, which charted at number 71.
