Namiko is a character who appears in the Gridman Universe within the anime SSSS.Gridman and its sequel movie Gridman Universe. She is a sixteen-year-old high school student, born on July 10, and stands 150 centimeters tall. She attends Tsutsujidai High School alongside protagonist Yuta Hibiki and Rikka Takarada, and is a friend and classmate of Rikka. Namiko is portrayed as a very outgoing and sociable young woman, embodying the traits of a typical modern high school girl. She is cheerful and interacts casually with her peers, often appearing in the background of everyday school life. Her motivations and personal ambitions are not explored in depth; she functions primarily as a supporting character who represents the ordinary student population of Tsutsujidai. Her role in the story is limited to being a friend and classmate, providing a sense of normalcy and community around the main cast. She does not possess any supernatural abilities or special knowledge about the kaiju events. After the defeat of Alexis Kerib, her life in Tsutsujidai presumably returns to normal, with no further development or significant changes in her character across the series.
