Overview
GRÄNDIR is an original song created for maimai でらっくす PLUS, composed by Rigel Theatre (also stylized Rigël Theatre), an alias of Inoue⊿ (Delta), and performed with vocalist ミーウェル (Miwele). Released on August 7, 2020 as part of the Heaven Area 2 (天界ちほー2) unlock campaign, the track sits at 170 BPM and blends orchestral textures with electronic drive, evoking the epic fantasy-game soundtracks common to the BMS (Be-Music Source) doujin scene from which the composer emerged. The vocal line is purely melodic; the song has no lyrics, with Miwele's voice woven in as an instrumental layer rather than carrying words. The rhythm is built around triplet-based (12分) subdivisions that give the song a rolling, energetic momentum. Its MASTER chart, designed by サファ太 (Safata), is a demanding 13.9-level affair loaded with dense Slide and Touch note patterns totaling 813 notes, while Jack's Expert chart provides a meaty 11.0 experience. GRÄNDIR later crossed over to CHUNITHM SUN in December 2022, and the song's celestial jacket art and title, possibly a stylized reference to Old Norse "gränder" (borders/edges), fit the Heaven Area theme of its origin.
