Schubert resides among four enchanted portraits of renowned composers within St. Claire Elementary School’s Music Room. Alongside Johann Sebastian Bach, who declares himself the "Father of Music," the tempestuous Ludwig van Beethoven, and the eccentric Wolfgang Amadeus Mozart, he safeguards one of three legendary medals capable of fulfilling a wish. Labeled "The Quiet One," Schubert’s subdued presence contrasts his peers’ more vivid personalities.

The quartet challenges visitors to craft a melody worthy of their approval. During an attempt by the deuteragonist trio, Mutsuko inadvertently presses a piano key while catching a fly, sounding a lone B-flat. The composers collectively deem this stark simplicity unexpectedly revolutionary, surrendering their medal. Schubert’s muted demeanor remains consistent throughout the encounter, though his individual responses remain unspecified in the scene.
