Marinal is a young South American girl who appears in the second episode of Lupin Zero. She comes from an indigenous tribe and is determined to recover a necklace that belongs to her people. The necklace has been stolen and is being transported on a train, which leads her to cross paths with a young Lupin III and Daisuke Jigen, who are also on the train for their own reasons. Marinal is motivated by a strong sense of duty to her tribe and her cultural heritage, driving her to take bold action to reclaim what was taken. Her personality is characterized by determination and a resourceful nature, as she attempts to retrieve the necklace despite being outnumbered and outmatched by the criminals guarding it. In the story, she serves as a supporting character who initiates the central conflict of the episode, bringing Lupin and Jigen together for their first collaboration. Her relationship with Lupin and Jigen is cooperative; they help her recover the necklace after realizing the injustice of the situation. Marinal’s character development is limited to this single episode, but she successfully achieves her goal and presumably returns the necklace to her tribe. She does not display any extraordinary physical or combat abilities, relying instead on her persistence and the assistance of the main characters. Her role underscores themes of loyalty and the protection of cultural artifacts within the broader narrative of the series.
