In the age of steam and machinery, mystery has never been far away from the world.
Moko, the lost and found clerk at Huiqiao Central Station, boarded a train that did not exist in the timetable at 0:17. Shadowless passengers, an accident file written three years in advance, a brass key to an unknown place, and a station that has never been recognized by any railway - Q-Null. All the clues are trying to prove that he has arrived in a place he has never been before.
Starting from the Sequence 9 "Apprentice", Moko continued to advance under the watchful eye of the church, secret organizations and Tarot Society, and gradually discovered that the real enemy was not eager to kill him, but wanted to register his identity for him, rewrite his choices, and make him a "passenger" that had already been arranged by fate.
When the past can be formed in the future, and fate can forge cause and effect, how can a person prove that he is still himself?
He had only one answer - push open the door that didn't belong anywhere.
