A man is journeying across an empty world with no memory of his path or his destination. Whenever he attempts to penetrate the cloud in his mind, he can only find two things; one is to go north. The other is Her. A stranger named Jigo appears to the man and insists on joining his quest. Who is this stranger and where did he come from? Is he a friend or just another figment of the man's imagination, conjured to fill the desolate road he travels on? The only way to find out is to take Jigo with him, all the way to the end.
