Kanae has accepted her life: a haunted house full of dead composers who treat reality like a punchline. The show knows exactly what it is and swings for absurdist comedy every single time, never once pretending the premise makes sense. When Wagner and Dvorak show up, it doesn't try to explain them, it just adds more chaos to a formula that works because Kanae's exhaustion is the only real thing in the room.

Kanae, an ordinary high school girl, finds herself sharing space once again with the house guests she likes least. Beethoven, known as Beet-san, and the carefree Mozart, called Motz, are back, along with Chopin, Liszt and Schubert, who are also living there uninvited. These composers have already shown they can save the world with their explosive tunes, known as Musik. Now two more Classicaloids, Wagner and Dvorak, enter the picture, and Kanae's patience is about to run out. The second season of the slapstick comedy mixes gags with classical music and asks what new realities these composers will create with their Musik.
