Natsumi Hinata

Height: 158cm

She is the eldest daughter of the Hinata family and Fuyuki Hinata's older sister. She is a Sagittarius and a student in Class 2-A of Kissho Gakuen Junior High School. Her partner is Corporal Giroro.

She excels in both academics and athletics. Perhaps because her mother is often away for work, she is also skilled at household chores like cooking. Her physical prowess often leads to requests for her to help out with various school clubs; while she enjoys sports and physical activity, she does not belong to any specific club because, as mentioned, she has to handle the housework at home.

However, regarding her studies, her grades have occasionally dropped due to interference from Keroro and his group.

On the other hand, unlike her mother and younger brother, she is not good at arts or cultural activities. She is not very skilled at drawing and has a unique sense for naming things. She is also a poor actor; perhaps due to her honest nature, her thoughts are immediately visible on her face. She is also bad at Rock-Paper-Scissors. She is uncomfortable with "occult" matters like ghosts and spirits, yet she possesses a spiritual sensitivity that causes her to frequently encounter paranormal phenomena. She also believes in things like horoscopes and the "Seven Mysteries of the School"—unscientific concepts that ordinary people tend to believe in.

She also dislikes "slimy things" like slugs (in fact, part of the reason she doesn't view Keroro and the other Keronians favorably is simply because they are frogs). She is an avid fan of the radio personality 623 and a listener of his show, "623's My Radio." She is also a fan of Dance☆Man.
