Rika Shiguma

A scientific prodigy and the fifth member of the Neighbors Club, this brilliant freshman joined the group specifically to pursue Kodaka after he rescued her from a failed experiment. Though she identifies as an anti-social shut-in and a passionate fujoshi, she is remarkably sexually forward, often using third-person speech and crude innuendos to shock her peers. Despite her eccentric, perverted persona, she is a deeply caring friend who works tirelessly behind the scenes to ensure the club's success.
