Megumi Sagano

Megumi Sagano is close friends with Karen Ichijou and Tsumugi Yuuki. She belonged to the girls' basketball team when she was in junior high, but became the manager for the boys' basketball team because there was no girls' team in high school. Though she seems concerned about her classmates' relationships, she does not seem to care about her own, and thus has no boyfriend.
