Suzumi Mori

Suzumi Mori is the former student council president of Seiran High School and an upperclassman whom the protagonist Nao encounters during the preparations for the school cultural festival. Her true identity is a Replica named "Ryo"—since the real Suzumi Mori has remained in a vegetative state following an accident, she has been living in the world in the original's place. Sharing the same circumstances as Nao, she possesses a profound understanding of the suffering and struggles faced by Replicas, making her a pivotal figure who guides Nao and provides her with emotional support.
