LANCE is an instrumental original composition by Ras, the alias of Kyosuke Yamazaki, introduced to maimai in the ORANGE PLUS edition on September 17, 2015. Running at 156 BPM with a duration of 2 minutes and 6 seconds, the track is driven by energetic electronic production with no lyrics, and its background movie was created by the artist 鑓田 (alpha complex). As one of Ras's earlier contributions to the maimai series, LANCE helped establish his presence in Sega's rhythm game ecosystem before his later work across both maimai and Chunithm. The song's categorization within the game has shifted notably across versions: it debuted under the JOYPOLIS genre in ORANGE PLUS, moved to ORIGINAL & JOYPOLIS from PiNK through FiNALE, then to ORIGINAL in the first でらっくす title, and finally settled into the maimai genre from でらっくす PLUS onward, reflecting the evolving taxonomy of the series itself. Over nearly a decade, LANCE accumulated a substantial chart family. Its original Standard charts, with the Expert (11+) designed by Jack and the Master (13+) by mai-Star, underwent level revisions across game updates as the difficulty scale expanded. A special UTAGE chart at 覚 (Satoru) difficulty was added in maimai MURASAKi PLUS on August 24, 2017, subtitled "なぞる順番を覚えるゲーム(中級編)" (a game to remember the tracing order, intermediate edition), hinting at a pattern-memorization gimmick. Nearly a decade after its debut, LANCE received a full set of DX charts in maimai でらっくす PRiSM, with the Expert chart designed by Luxizhel and the Master by サファ太 (Safata), bringing the track into the modern DX format with Touch note integration.
