The Summer Hikaru Died narrates the story of two boys, Yoshiki Tsujinaka and Hikaru Indou, who share a close bond in their rural Japanese village. Their harmonious friendship takes a dark turn when Hikaru returns from the mountains changed and seemingly not himself. Yoshiki, who recognizes the unsettling transformation, confronts Hikaru six months later, only to learn that an otherworldly entity has taken over Hikaru’s body.

This entity, masquerading as Hikaru, lays bare its feelings, offering confrontational love and a chilling death threat to Yoshiki. Bound by his memories and grief for his lost friend, Yoshiki grapples with accepting this new being, even as it poses a threat to those around him.

Is The Summer Hikaru Died a BL series?

As Hikaru is no longer fully human but an otherworldly creature, the complexities of his feelings remain undefined. As the story progresses, he himself questions the essence of the love he feels for Yoshiki, adding another layer of intrigue to their dynamic.
