宿星審判 (Shukusei Shinpan) is a driving instrumental composition by the enigmatic artist suzu, crossing over from CHUNITHM CRYSTAL PLUS into maimai DX UNiVERSE under the ONGEKI & CHUNITHM (オンゲキ＆CHUNITHM) genre category. Propelled by a brisk 189 BPM and layered electronic instrumentation with no vocals, the track carries the intense, high-energy character typical of CHUNITHM boss songs. The identity of suzu has long been a subject of fan speculation. The musical style closely parallels that of wa., a BMS (Be-Music Source) composer known for works such as Black lotus and for several CHUNITHM contest entries whose melodic phrases appear to be quoted in this track. A wordplay theory further links the names: suzu (鈴, "bell") → ring (both the sound and the object) → 輪 (wa, "circle") → wa. No official confirmation of the alias relationship has been issued. The song's MASTER chart, designed by ぴちネコ (Pichineko), is rated level 14 with a constant of 14.3 and contains 1,074 notes, including an unusually high 110 Touch notes that give the chart a distinctive tactile character. The EXPERT chart was designed by サファ太 (Safata). Beyond maimai, 宿星審判 earned the distinction of being the first non-オンゲキ original to receive a level 15 chart in オンゲキ, and it was featured as an online preliminary challenge song for KING of Performai The 3rd, Sega's cross-title rhythm game tournament. Unusually for its era, the song reached the International (Asian) version of maimai DX on July 30, 2021, over a month before its Japanese release on September 16, 2021, marking the first time a brand-new song debuted in the Asian version of maimai ahead of Japan. An extended arrangement titled 宿星審判 -眩耀、最果てにて- was later included on the CHUNITHM 10th Anniversary special CD.
