[EN] Yoshiki Tsujinaka and Hikaru Indo are two teenage boys and childhood friends living in a small town in rural Japan. Despite having opposite personalities and different hobbies, the two maintain a close friendship. However, on a winter day, Hikaru is fatally injured while hiking in the mountains alone. Before he dies, a mysterious eldritch being comes across him and consumes him, becoming him physically in the process. This „Hikaru” has all the feelings and memories of the original, yet remains a separate being, something Yoshiki realizes rather quickly. Yoshiki still wants to stay with „Hikaru”; however, his alien nature, along with other eldritch beings and hunters of said beings, may make that impossible.
