Latar Belakang: In the Taisho era, in 1915, a 20-year-old young woman named Ayane from the noble family called the Miyazawa family was at home ready to play the piano and as as she played Franz Liszt's Hungarian Rhapsody No. 2 and is poised at the piano. Throughout the performance, Ayane engages in playful banter, responding to a ringing phone inside the piano with her trademark catchphrase, "Hm, yes?" She cleverly incorporates musical references, such as singing "Fi-ga-ro!" during a familiar three-note sequence, adding a comedic twist to her piano playing. As Ayane navigates through the piece, she encounters a demon named Doma who serves Muzan Kibutsuji that becomes a persistent freak. The encounter escalates into a musical duel, culminating in a boogie-woogie showdown. Despite momentarily trapping the demon, Ayane is ultimately outwitted as the demon reemerges, performing a surprise finale on a miniature piano. In a comedic climax, Ayane confronts the final frenzied pages of the Rhapsody holding an axe in case Doma comes to peep at her like a perv, culminating in exasperation as the mouse steals the spotlight with its unexpected performance. Frustrated yet undeterred, Ayane delivers the closing notes with characteristic wit, concluding the performance with a humorous flourish. What happens next?
