Kōko enters Banri's apartment alone, missing him deeply. After sniffing his pillow, she performs The Exorcist to calm down. Nana catches her and suggests using the act in her show, but Kōko refuses. Kōko strangles Nana to prevent her from telling Banri about her visit. Nana then uses Kōko as a guinea pig for a new idea. Meanwhile, Linda and her brother arrive at Banri's home for the class reunion. During the drive, Linda notices the mirror Kōko gave Banri and realizes he is nervous. At school, Banri is too anxious to move, so Linda tricks him into entering. They play a dodgeball rematch where Linda's team previously lost on a technicality. Linda uses the same rule to win. Classmates welcome Banri warmly despite his memory loss. They share stories of the old Banri, causing him embarrassment. Their teacher adds more details, worsening his feelings. Taking photos with former classmates helps him feel better. On the way home, Linda and Banri discuss accepting their situations. Banri photographs the bridge where he fell and sees a vision of the accident. He tries to save the ghost Banri, but the ghost forces himself to fall. Banri drops and breaks the mirror, wondering if his memories are returning.
