Fushigi Densha

Our protagonist awakens in a bar in front of the station, intoxicated and drunk.
He finds himself in a strange city rife with insanity and bereft of all sense. Yet, he spots a mysterious train rushing to the platform.
In the absence of a great many alternatives, he boards the train and sets out on a journey full of bizarre stories and lots of sexual temptations.
Except when he finally gets to the terminal station, the sun has long hidden behind the horizon, so he decides to wait for the dawn in a bar conveniently placed in front of this very terminal station.
Once again drunk, he awakens and finds himself in a strange city with a mysterious train running through it. Having lost all of his previous memories, our hero gets on it and sets on a mysterious journey once more.

How long will this seemingly never-ending journey last?
Will he ever make it home?
