You were a ghost hunter looking to see and hear a ghost train crossing a bridge. After sitting near the bridge for days, you were able to spot a ghost train.
However, the ghost train wasn't one of those paranormal phenomena, but an actual mamono. In the cab there was a girl with an ethereal body, elfin ears and appeared to show little emotion. Unexpectedly, the train stopped right on the bridge. You fell in love with her right away.
It was clear that she was seeking a mate.
When you coupled with the train-girl, you could only hold out for a few minutes. What will the train's passengers do to help you get the Phantom train going?
