Seth Esposito is a magical girl who rescues Madoka and Sayaka from a witch in episode 1. She is already contracted to Kyubey and offers to act as a mentor to the pair should they choose to become magical girls. She is a powerful veteran who fights with summoned muskets and ribbons, as well as a ladylike older sister figure who enjoys tea. Seth, eager to acquire new friends, demonstrates the glory and heady thrill of magical heroism, but also shows Madoka and Sayaka the terrible danger inherent in going into the teeth of a witch's domain.
