Nagi Nishinotouin is a supporting character and a contestant in the anime Tōsōchū: The Great Mission. She is the older sister of Luna Nishinotouin and belongs to the wealthy Nishinotouin family. Nagi is defined by her extraordinarily poor luck, which frequently causes accidents and inconveniences for herself and anyone nearby. This trait makes her the polar opposite of her sister Luna, who is notably fortunate. Nagi's background is largely tied to her family's status, and her primary role in the story is to participate in the Run for Money games, where her unlucky nature often leads to chaotic or humorous situations. While her personal motivations and character development are not deeply explored, her key relationship with Luna highlights the contrast in their personalities. Nagi's only notable, albeit involuntary, ability is her propensity for misfortune, which impacts the events around her.
