死ぬな！ (Shinuna!, literally "Don't Die!") is a high-energy J-pop track by Japanese musician Kocchi no Kento (こっちのけんと), added to maimai でらっくす CiRCLE at its launch on September 18, 2025. Composed by Kocchi no Kento together with GRP, who also handled arrangement, the song originally released as a standalone single/album of the same name in 2022, three years before its rhythm-game debut. Clocking in at a brisk 220 BPM and running 2:07, its driving instrumentation and shouted chorus belie lyrics that confront mortality with defiant optimism, repeatedly urging the listener not to die and instead to think of three wishes. The official music video, directed by HONA of zow films, visually amplifies the song's chaotic, vibrant energy. In maimai, the song received four DX-standard charts plus an UTAGE (宴) endurance chart. The MASTER chart (level 13, constant 13.3) was designed by ロシェ@ペンギン (Rocher@penguin), while the EXPERT chart (level 9+, constant 9.6) was handled by Luxizhel. Notably, the EXPERT chart uses zero Touch notes, a compositional choice that sets it apart from many DX-era charts at a similar level.
