Marco

Marco (マルコ) is a main female character in the Marco and The Galaxy Dragon series by Tokyotoon.

Description
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.

Based on the treasure map (a photo of a partially burned and indistinct mother) that she had been holding for a long time, she searched for a "mother", a treasure that had not yet been seen, and found his hometown, the gold cord city of the earth.
