アスノヨゾラ哨戒班 (Asu no Yozora Shoukaihan, "Tomorrow Night Sky Patrol Squad") is a VOCALOID track by producer Orangestar featuring IA's vocal synthesis, originally uploaded to niconico in 2014. The song quickly became one of Orangestar's defining works within the VOCALOID doujin scene, earning millions of plays and lasting recognition as a modern classic. Its lyrics trace a narrator who begins in despair, crying out "明日よ！明日よ！もう来ないでよ！" (Tomorrow! Tomorrow! Don't come anymore!), before being pulled forward by a companion toward hope under the night sky. The track appears on Orangestar's 2014 album 未完成エイトビーツ (Mikansei Eight Beats) and was accompanied by a music video created by M.B. A band-arranged version titled キミノヨゾラ哨戒班 was released to mark the song's first anniversary, and that arrangement also appears in the maimai series. The song crossed into SEGA's arcade rhythm game ecosystem first through CHUNITHM PLUS in 2016, then joined maimai でらっくす Splash on January 21st, 2021 with a shortened game edit. Its Master chart (level 12+ / constant 12.8) designed by はっぴー is recognized among players as a demanding slide-and-Break-heavy pattern, while the Expert chart (level 9) was designed by 隅田川星人.
