High school students Kanae and Sōsuke live in a provincial town that is trying to revitalize itself with music. One day, suddenly "Classicaloid" versions of Beethoven and Mozart appear in front of Kanae and Sōsuke. When the suspicious-looking Classicaloids play music they call "mujik," it has a strange power: stars start to fall, and giant robots appear. Now every day is tumultuous. Eventually, more Classicaloids start to appear such as Bach, Chopin, and Schubert.
