Concetta, eldest daughter of puppet troupe leader Peppino, performs alongside her father and sisters Fiolina and Giulietta in their itinerant family variety show. She specializes in puppetry, excelling at manipulating and presenting puppet acts within their performances.

As part of the Peppino Troupe, previously known to Marco in Genoa, Italy, Concetta and her family encounter him again in Buenos Aires, Argentina. They accompany Marco to Bahía Blanca during his quest to find his mother, offering companionship and support.

Her background firmly places her within this traveling performing family. Peppino relies on outdoor puppet shows for their livelihood, with Concetta and her sisters integral to the act. Her role remains that of a consistent supporting member of the Peppino Troupe, aiding Marco during this segment of his journey.
