Overview
Endless, Sleepless Night is a eurobeat arrangement of Master Spark (恋色マスタースパーク), the Stage 4 boss theme from 東方永夜抄 〜 Imperishable Night, the eighth mainline Touhou Project game. The arrangement was produced by samfree, a key figure in the Touhou doujin music scene, and released through the circle A-One on the 2010 compilation TOHO EUROBEAT VOL.1. Vocalist Kanipan delivers English lyrics that paint a picture of longing beneath a starry sky, a nocturnal mood that echoes the song's title.
In maimai, Endless, Sleepless Night debuted on August 22, 2014 as part of the GreeN PLUS update, during the arcade series' early years when Touhou doujin arrangements were a staple of the song library. The song went through several visual updates over its lifetime: the jacket art was refreshed in maimai ORANGE, and its original gameplay video was replaced by a static jacket image in maimai でらっくす. More than a decade after its original appearance, the song received DX charts on July 4, 2025 as part of the PRiSM PLUS update, initially locked behind a Stamp Card campaign before a general unlock on March 19, 2026.
