Overview

デビルじゃないもん (Devil janai mon) is a Vocaloid track born from a collaboration between DECO*27 and Pinocchio-P (ピノキオピー), two of the most influential producers in the Japanese Vocaloid scene. Featuring Hatsune Miku on vocals, the song was originally released as a single in 2023, with arrangement credited to Rockwell and Pinocchio-P and a music video produced by OTOIRO. The track made its rhythm-game debut in CHUNITHM LUMINOUS PLUS before arriving in maimai DX PRiSM as part of the September 12, 2024 update. The title translates to "I'm Not a Devil," and the lyrics playfully lean into the classic ironic trope, a character emphatically denying being a devil while the song's own chorus undercuts the claim. Musically, the track blends DECO*27's accessible pop-rock hooks with Pinocchio-P's signature internet-culture edge: deadpan newscaster interjections like "【悲報】" (sad news) and repetitive "堕" (fallen/corrupt) chants give the song a distinctly online, satirical flavor. In maimai, the MASTER chart (Level 13, constant 13.0) was designed by Luxizhel, known for technically demanding layouts, while the EXPERT chart (Level 9+, constant 9.6) was designed by アマリリス (amaryllis).
