Maestro Vento hails from Museaca—alternatively called Musica or Mushka—where he oversees the Hall of Farres as general manager and commands the planet’s musical robots. His design and persona draw direct inspiration from Ludwig van Beethoven, including the detachment of his right ear due to hearing damage. This impairment compelled him to pioneer a unique composition technique, sensing vibrations through his staff instead of auditory cues.

Vento actively shaped Museaca’s musical culture until private performances faced a system-wide ban. This prohibition lured a destructive cosmic entity known as Noise, which devoured the planet. Amidst Museaca’s collapse, Vento was composing in the Hall of Farres when he ceased functioning mid-score, entering prolonged dormancy. The Hall acted as a lifeboat, carrying him, young survivor Mikka, her caretaker robot Chapek, and other musician robots to safety.

After drifting near Earth, Vento remained inert until Nobita and his friends discovered and restored him using Doraemon’s gadget. Revived, he revealed Museaca’s fate, linking the Noise’s emergence to suppressed public music and tracing its spread on Earth to Nobita’s earlier wish for a music-free world.

Recognized as Chapek’s mentor from pre-cataclysm times, Vento united Nobita’s group, Mikka, Chapek, and the musician robots against the Noise. Their collective performance of his "Earth Symphony" repelled the entity, shielding Earth. Post-victory, Vento stayed aboard the Hall of Farres as it journeyed onward. Chapek later noted their symphony had signaled other surviving Museacan vessels, suggesting potential reunions with refugees.
