Yoru, Tooku e Mukau
Another commenter did not "get" this. Or at least, the benevolent aspect of this. The tall man is like a shinigami. The girl is sickly and due to depression has given up on life. The shinigami is leading her to "the far away place" beyond the boundary of land/sea (death). But he is clearly leaving the choice to HER. The Shinigami has also somehow informed the young boy the girl would be there/when/that night. The boy comes to confess and show her she's the "special" thing (the bag on her head). She's now happy and wants to try hard again to live and get better. The Shinigami or dream god --if this is a supernatural dreamland experience with the three, versus waking life, which is also possible--or whatever he is says it's been up to her and goes into the sea. All along, it's been about love. The girl twice mentions how "the moon is beautiful." Well, that's a euphemism for "I love you" in Japanese, saying the feeling without saying the direct, embarrassing words. Tsuki vs suki. (Google it, it's pretty well known to be a substitute for a confession.) The girls feelings of love saturate this. And then the boy's. And love brings life. The tall man was never a danger to the girl. He came to change her life, and she chose LIFE. The title is about Night (also a euphemism for death and/or sadness, loss of hope, depression). Facing the distant bay (the distant shore is often used to signify death, going across the sea or river being the passage to THE OTHER place). The girl is facing that faraway place, and it is her decision. She faced death, and she chose to live and to love.
