Nene Mikumo is a supporting character in the anime Venus Versus Virus. She is the older sister of Riku Mikumo and the cousin of Sumire Takahana. Her appearance includes medium-length pink hair and green eyes. Nene possesses a very loud and cheerful personality, often approaching situations with energy and enthusiasm. Her primary motivation is her protective and caring nature toward Sumire, whom she tries to look out for like an older sister. She also actively encourages her brother Riku in his attempts to ask Sumire out on a date. In the story, Nene serves as a source of familial warmth and comic relief, appearing primarily in scenes related to Sumire’s personal life rather than the main supernatural conflict. Her role is further defined by a moment of misunderstanding: when Sumire asks to move into the Venus Vanguard headquarters, Nene secretly watches and jumps to the wrong conclusion about the situation. Nene does not possess any supernatural abilities or combat skills; her significance in the series is grounded in her relationships and her cheerful, supportive presence. Throughout the series, she does not undergo major character development, remaining a steady, friendly figure who anchors Sumire to her normal life.
