Coti, also known as Josephine Polinyac, first disrupts a mountain race involving protagonist Gen Todoroki, sending her vehicle crashing off a cliff. Gen intervenes to rescue her. She later surfaces in Kenya, joining Gen's rally support team, though her specific function within the team is undefined. Her presence in Kenya lacks explicit explanation. Coti is the daughter of the founder of a major French company on the verge of partnering with the Japanese corporation sponsoring Gen's rally efforts. An initial plot point establishes her as a runaway from school, but this thread sees no further development or resolution. Her interactions primarily consist of following Gen and participating in team activities, with her motivations for being in Kenya or her connection to the rally operation remaining unexplored. The narrative offers minimal exploration of her background, including family connections or personal history. Similarly, her development throughout the story remains limited, showing no significant evolution in her role or personal arc.
