SQUAD-Phvntom- is a hardcore collaboration track produced by Getty and DJ DiA, originally composed for SEGA's CHUNITHM NEW before crossing over into maimai でらっくす BUDDiES in September 2023. The title is a stylized rendering of "Squad Phantom" (スクワッド ファントム), evoking a tactical-meets-ghostly imagery that suits the track's aggressive, synth-driven production. At 200 BPM, the song showcases Getty's signature heavy bass-drop aesthetic, he is a trackmaker affiliated with both Hifumi,inc. and the long-running Japanese hardcore label HARDCORE TANO*C, while DJ DiA, founder of the Kirara Records label, contributes complementary electronic production. The result is a relentless, high-energy cut that sits comfortably in the ONGEKI & CHUNITHM category within maimai. In maimai, SQUAD-Phvntom- received DX charts across four difficulty levels. The EXPERT chart (level 12+) was designed by Jack, while the MASTER chart (level 14) was handled by Ruby, who packed it with a notably dense 1,064-note total including 140 Break notes and 77 Touch notes, making it one of the more physically demanding charts of its era. The song was initially exclusive to players who linked a corresponding CHUNITHM cabinet, but became generally unlocked in December 2023.
