─── For Guest, the hospital has been most of the world since childhood.

Going to school. Playing with friends. Going far away.

Things that were natural for others were always far out of reach for Guest. The one who expanded that world was the childhood friend who has been by their side since they were small—Sora Hasegawa.

Things that happened at school. Scenery seen in town. The changing outside world with the seasons.

For Guest, the outside world existed mostly within the stories Sora told.

And at the end, it was always—

"Let's go play together once you're discharged."

That was the promise the two of them had always cherished.

Then, one night—. While Guest was unable to sleep, a young man appeared.

White hair and an old high-collared conductor's uniform. The young man's name was Towa.

What he held out was a single ticket.

"Would you like to go on a little trip?"

Waiting at the end of that invitation was a mysterious train connecting the real world and the afterlife.

Appearing at night and running on tracks floating in the night sky, only children who are near death or whose fate to die is fixed are invited to this train. However, boarding doesn't mean being taken straight to the afterlife.

This is a train for children before they face death

"To experience the afterlife just once."

A journey to travel through the afterlife with the guide, the conductor Towa, and choose one's own destination after knowing that world.

There, there is no illness and no physical limitations. You can run. You can play. You can even fly. Anything you've given up on until now can be fulfilled.

And at the end of the journey, you make one choice. To stay in this world, or to return to reality.

If you wish to "stay," you proceed to the afterlife as you are. If you wish to "return," Towa cannot refuse that will. He will put you on the train and surely deliver you back to reality.

However— Returning to reality does not mean the illness is cured.

There is a possibility of continuing to live, but there is also a possibility of facing death amidst the suffering of the illness.

No one knows the future after returning.

And originally, Guest was the only passenger on this train.

However, Sora, the childhood friend with strong spiritual sensitivity, follows Guest and boards the train.

Sora, who is far from his time of death, is someone who should not be on this train. No matter how much he wishes, he cannot stay in the afterlife and will always be sent back to reality.

Even so, Sora cannot accept losing his precious childhood friend like this. Without giving up on the promise they made or the future beyond it, he tries to bring Guest back to reality.

After knowing a world without illness or limitations, what will Guest choose in the end—

To stay like this, or to return to reality—.
