The group's straight-man corrector
Rin Eiyuuzaki shares a long history with both Sota and Kikuno, having been close friends with them since early childhood. Back then, her androgynous appearance often led others to mistake her for a boy. When fate reunited them, neither side recognized the other at first, causing Rin to treat Sota with a noticeably stern attitude—until the truth came to light and her tough exterior melted away almost instantly, leaving her flustered and red-faced at the slightest provocation. As a standout athlete and key player in the Kyudo Club, she brings both precision and dedication to the sport. Within the mission dormitory, she naturally takes on the role of the level-headed voice of reason, reining in her companions whenever things spiral out of control.
