Overview
インパアフェクシオン・ホワイトガアル (Imperfection White Girl) is an original song by producer Tsumiki (ツミキ) featuring vocalist Tsukino (月乃). It first appeared in SEGA's CHUNITHM SUN as a CHUNITHM original track before crossing over to maimai でらっくす BUDDiES on February 29, 2024, a leap-day release. The title is a stylized Japanese-English portmanteau blending "imperfection" with "white girl," and the lyrics weave themes of identity, performance, and self-discovery around the imagery of a pure white canvas and the theatrical masks people wear. At 207 BPM, the track drives forward with the fast-paced, electronically charged production style Tsumiki is known for. The maimai DX chart lineup spans four difficulties, with the level-14 MASTER chart (constant 14.2) designed by ミニミライト, notable for 172 Slide notes out of 1,067 total, and the EXPERT chart by サファ太. In the Asian version of BUDDiES, the song was initially unlockable by linking gameplay with the corresponding CHUNITHM cabinet, tying the two rhythm-game ecosystems together.
