Nene Fujiyoshi is the younger twin sister of Tsuyoshi Fujiyoshi and a supporting character in Cosmic Baton Girl Comet-san. She and her brother are among the first Earthlings to meet Comet shortly after the princess arrives on Earth, and they become her close friends and playmates. Nene is depicted as a tomboyish and precocious child, full of energy and curiosity. She is easily recognizable by the cowlick on her head that falls to the left side. Nene’s primary motivation is to have fun and explore the world alongside Comet, whose magic and star powers fascinate her. She and Tsuyoshi are among the few humans who know that Comet is a magical being from another world, and they often join her on her adventures. Nene enjoys playing rough and can sometimes annoy Comet’s pet, Rababou, with her boisterous behavior. She shares a close bond with her twin brother and treats Comet as a special friend, helping her adjust to life on Earth. Over the course of the series, Nene remains a cheerful and loyal companion, though her personal development is not heavily emphasized. She has no magical abilities of her own, but her willingness to accept Comet’s true nature makes her an important confidante and ally.
