When the girl woke up, she had lost all her memories.
She found herself aboard a train running through the stars.

It seems to be a strange kind of train—one that only a few lives, those who have wished for death, ever receive a ticket to ride.
Stranger still, they say the memories you’ve forgotten begin to appear, taking shape within the train itself.

To reclaim what was lost, you must face each memory—gently, and in the right way.
That is the key to getting them back.

But you are not alone.
With the help of your twin brother—who boarded the train with you—
and a quiet companion who’s been riding it far longer than anyone else,
you’ll begin your journey to face what you’ve forgotten.
