The Beluga is a long-distance train that travels across the North.
For seven days, fourteen carriages drove all the way to the snowfields, the Old Kingdom, the North Sea and the sunless wilderness. Gojo Satoru originally just thought that taking a train with Megumi Fushiguro for seven days sounded interesting - to see the scenery, eat something sweet, and experience a trip that would be so slow for normal people that it would be a waste of time.
Until the first night on the bus, a passenger disappeared from the locked room.
Then, a figure running side by side with the train appeared outside the window; in the photo of the first flight forty-seven years ago, there was a white-haired man who looked exactly like Gojo Satoru; the non-existent station was lit up at midnight, and the dead stood in the snow waving; the shadow began to leave its owner, the old ticket wrote the destination on its own, and the train announcement repeatedly reminded:
Do not talk to passengers who say they have been traveling for more than seven days.
What's even more troublesome is that they gradually discover that the real danger on this train is not the ghost.
Beluga will find a "most wanted place" for each passenger.
The person you lost, the home you never had, the regrets that never happened, are stuck in the past one day... You can have them again as long as you open the door.
If there really is what you want most in your life, would you still be willing to move forward?
Intention: A snow train that is always looking for the "destination" for passengers, and two people who decide not to let fate make choices for each other.
