Overview
失敗作少女 (Shippaisaku Shoujo, "Failed Creation Girl") is a high-energy Vocaloid track born from an unusual cross-circle collaboration between two of the most prominent producers in the Japanese Vocaloid scene: Kairiki Bear (かいりきベア) and MARETU. Featuring Hatsune Miku, the song barrels along at an intense 235 BPM, a tempo befitting both producers' signature styles of frantic, emotionally charged electronic rock. The title suggests themes of inadequacy and self-perception, framing the vocalist as a "failed creation", a lyrical angle consistent with the raw, introspective writing both artists are known for. The song was added to maimai でらっくす UNiVERSE on December 24, 2021, and falls under the niconico＆ボーカロイド (niconico & Vocaloid) in-game genre. Its original upload appeared on NicoNico Douga (sm35513238), alongside an official YouTube release. In maimai, the MASTER chart, designed by 翠楼屋 (Suirouya) at level 13 (13.1), packs 795 notes into its short runtime, making it a stamina-intensive play for advanced players, while the EXPERT chart by 隅田川星人 (Sumidagawa Seijin) offers a denser-than-typical level-10 experience at 450 notes.
