Reiko Saeki

As Reishirou’s younger sibling, this dedicated member of the First Student Council maintains a distance from the central conflicts involving Aine and Asura Machina. Though she shares a warm bond with Aine from before her transformation into a Burial Doll, she remains focused on her own path. She also harbors a visible, bashful crush on Tomoharu, even going so far as to change her hairstyle just to catch his eye, despite her outward denials.
