Keisuke Hirose

As a childhood companion of Shouya Ishida, this former classmate played a complicated role during their elementary school years. While he participated in the harassment of Shouko Nishimiya, he often appeared visibly uneasy with the cruelty. His character dynamic shifted significantly as he grew older, transitioning from a reluctant bystander in the bullying of Shouko to an active and willing antagonist toward his old friend, Shouya.
