Overview
Beat Opera op.1 is a maimai original composition by bermei.inazawa, the alias of Koichi Murakami, founder of the doujin music circle studioCampanella. The track debuted in maimai でらっくす FESTiVAL on February 3, 2023 as part of the Heaven Area 6 (天界ちほー6) unlockable song set. Its title, employing the classical "opus" numbering convention (op.1), signals the beginning of a planned series, and the music carries an operatic, story-driven weight befitting that framing.
The song is accompanied by an unusually elaborate flavor text that reads like a fairy-tale prologue: a great calamity (厄災) ravages the land of No-グ, feeding on human suffering. Four young beastmen warriors rise to challenge it, fall one by one, and with their last breaths pray to the goddess Dana (ダーナ) to protect the people in exchange for their eternal devotion. The text frames this as a bedtime story told to a child named Dean (ディアン), who drifts off to sleep mid-tale, a gentle, melancholic twist on the epic fantasy setup.
The video/movie was produced by サム (Sam). The track's BPM (145), moderate length (2:14), and lack of lyrics keep the focus squarely on the instrumental arrangement and the atmospheric story the music and visuals convey together.
