Himari Haruno

She is a female student who serves as the manager of the baseball club and is in the same class as Mikage Sakurai. At first, she saw Mikage Sakurai as a "mysterious and cool character," but her impression changed after observing Mikage’s activities in her club. She expressed interest in the Earth Sciences Club, saying she “doesn't really understand it but finds it interesting,” which caused Mikage Sakurai to reconsider her belief that her classmates wouldn't understand her interests. During the school festival, she visited the Earth Sciences Club's exhibit with two male baseball club members who had helped with the drilling survey.
