A still, white space expands as far as the eye can see. A man who's lost his memory awakens. An enormous door stands before him, and there's an old temple in the distance. The building seems to be calling to him, and the man approaches it. There's an old piano there. The moment he touches it, horrifying memories return.
An original work created by ECHOES, represented by KODAMA Tetsuro. Production was started with the goal of creating a film that had a “confusing plot, but would be visually appealing.” Eventually, it eclipsed that original idea, with the scenario and storyboards constantly being refined and the film being created using trial and error over a period of 3.5 years.
