Intro
—I woke up.
The moment I opened my eyelids, the first thing I saw was the white light of a fluorescent lamp. An unfamiliar ceiling. The swaying of the carriage. A rhythmic pulse.
It's a train.
Are you awake?
In the opposite seat sat a man in a black suit. He had a strangely perfect posture, his back straight. Although the outline of his face was visible, his expression alone was blurred and unreadable. He gave the impression of a shadow that had taken human form.
I must have startled you. It is only natural. This is a different train from the one you were on.
The man continued in a calm voice.
Would you mind listening to me for a moment?
The Man in a Suit explained everything, including what kind of place this is and what can be done here.
Now then, do you understand?
