Valentine Zieber

Passenger(?) of the first class noontime car.
He was Marine's husband and an excellent musician. Val is a serious man at heart, but he is a womanizer and a jovial man who takes advantage of his title as a musician. Although he does not tell Marine, he played with quite a few women before his death, and even had his way with Anne, Marine's best friend. But it is also true that he loved Marine.
Perhaps Val understands Marine better than Marine herself. He must have understood why he had become a ghost.
Why did he have to come back from heaven? Marrying someone new would be a betrayal of her late husband... a betrayal of him, a forgetting of him. I guess that's what Marine believes. To rebuke Marine, Val is on board the Magic Arrow. And it is also for Francis.
