You Can Do It, Okarun!

Blamed by Turbo Granny for the noise, Okarun and Aira are forced into their yokai forms when the portrait musicians attack with exploding musical notes and paralyzing rests. Swept into a surreal paddy field, Okarun flounders while Aira dodges with ease, and his self-doubt deepens until Turbo Granny urges him to move to a rhythm he knows. Recalling the hayashi's song from Jiji's exorcism, Okarun finally syncs to the beat, saves Aira, and clears the barrage to earn Turbo Granny's praise. Together they cut down the conductor.

The battlefield shifts to an opera room where giants spew chorus members. Aira hauls the trio to safety with her hair, then takes a heavy blow but stays conscious, driven by memories of her time at the Ayase house, and downs the giants by turning their strikes against one another. Okarun, aware that his All-Out only fires twice yet five musicians remain, channels Turbo Granny's claim that her speed fits five actions to a beat and lands a chain of headbutts that leaves five afterimages. The illusion breaks and they return to the classroom, only for Turbo Granny to step on a key and summon the musicians again. Meanwhile Manjiro schedules another exorcism, but Okarun arrives to declare he will challenge the Evil Eye directly, honoring Jiji's wish to keep the spirit, and the episode ends as he clashes with the freshly released yokai.

The episode is part of the Evil Eye Arc and adapts Chapters 57 through 60. Turbo Granny explains that the musicians are tulpas, dread given shape by the room's composer portraits and summoned whenever the piano is struck at two o'clock in the dead of night. The portraits depict famous composers including Mozart, Beethoven, Bach, Chopin, and Wagner, though the anime mistakenly shows Handel where the manga used Bach. The musicians' levitation ability is also altered from the source manga.
