He came back—but not the way he left.
Yoshiki knows something is wrong. The boy who returned from the mountains looks exactly like his best friend Hikaru—but whatever came back isn’t human. Despite the growing unease and the strange, creeping phenomena surrounding them, Yoshiki chooses to stay by his side. As their bond is tested by fear, grief, and the unknown, the quiet countryside becomes a stage for something deeply unsettling. Haunting, emotional, and atmospheric, The Summer Hikaru Died blends horror with a poignant exploration of friendship and loss.
