Special Express 'Mithishio'

Seiji is a train conductor aboard a special express called Michishio. To the outside world, it appears to be a normal train, but its true purpose is far more sinister. The train is designed to capture young girls and train them to become sex slaves.

A rumor spreads among young people that anyone who boards "that" train will disappear. Most dismiss it as a myth, but the Michishio is real. Once every few months, the train reveals its true nature. Seiji, using his special training abilities, can do whatever he wants to the girls on board. Now, another departure of the Michishio begins.
