"It's like, for them, life just went on, and then we drop back into it and we don't fit anymore. Like they've already figured out how to survive without us and we're just here, in the way, until we can figure out how to get our old lives back. But we're not the same people, and probably never will be."

After being away for over a year, Alfonse Keller has returned from the trenches on Teuton's western front, fighting in the war that's broken out against the Steppes. He should feel relieved now that's he's back in his own village in the care of his brother Ernst, but he's not. It seems like nothing has changed except for him, like he's a traveler from a different world.

When Alfonse left to join the army, he was a natural magician making a name for himself, but after a tragic incident resulting in the death of his friend, and his own crippling injury, he no longer has the ability to use magic.

Suffering from constant nightmares and revisited trauma, Alfonse can't get the trenches out of his head. Ernst tries to help, but he doesn't really understand either. How can he, when Alfonse doesn't really understand himself? He feels like a phantom, standing on the outskirts of a life he'll never live again.

As Ernst tries to do everything he can for his brother, he can't help but feel like Alfonse is slipping away, that maybe part of him never left the trenches at all. But how can he save his brother when Alf refuses to let anyone in?
