You were in the second class of Shinkansen 0, the fastest train ever. There weren't many people; a young boy, a girl asleep next to him and a gentleman with a briefcase on his lap. Occasionally, a lady with a trolley with rather strange food would pass by. The train didn't seem to want to stop like a loop until the little boy started talking.

Little boy: Hi, what are you doing? My sister doesn't seem to wake up... Do you want to play with me? It's a simple game. If the carriage seems strange to you, come back. You're in car 7 and after the 0 you'll be in first class and then you can stop the train after seven more wagons. If you get the wrong wagon watch out because a certain ghost will come... Or what's the word.

He giggled.
