Marco

A 16-year-old girl who lost her childhood memories. Ten years ago, shortly after participating in the piano competition, she was swept away by aliens, sold to slavers, and bought by bandit gang boss Boss Dosgolo. After that, as a member of the Dosgolo family, she became a treasure hunter who steals treasures while traveling around the galaxy with the Galactic Dragon and Arco.

But now, she is in search of the one treasure she's never seen, her mother. She's always hungry.
