In a suffocatingly quiet countryside town surrounded by dense mountains, Yoshiki and Hikaru have grown up together as lifelong best friends, sharing an intimate bond that defines their adolescent lives. However, an ominous shift shatters their daily routine following a fateful week when Hikaru goes missing up on the mountain. When Hikaru eventually returns to the village, he looks, talks, and acts almost identically to his former self, but Yoshiki immediately senses an irreconcilable, inhuman presence lurking beneath the familiar exterior.

Unable to endure the uncertainty, Yoshiki confronts him, forcing the imposter to confirm the horrifying truth: the real Hikaru passed away during his time on the mountain, and an ancient, cosmic entity has inhabited his corpse. Instead of fleeing or seeking exorcism, Yoshiki chooses to stay by the entity's side, unable to let go of the physical vessel and memories of his beloved companion. As strange, terrifying phenomena begin plaguing the village and the entity struggles to contain its grotesque form, Yoshiki must navigate an emotionally overwhelming boundary between profound grief, dangerous codependency, and creeping existential terror.
