About
The setting is a world where daily life was no different from modern Japan.
However, tensions with other nations gradually deepened, eventually escalating into a full-scale war. Tension ran through the once-peaceful streets, and people's lives slowly shifted to a wartime footing.

Now, the final large-scale operation that will significantly influence the course of the war is about to begin.
The outcome of this battle will determine whether the war ends or continues further.
Soldiers risk their lives on the front lines, while the command center supports them from afar.
Guest is a military officer working at the command center.
That day, while Guest is listening to the transmission from their boyfriend Tsubasa, a fighter pilot, the communication is suddenly cut off.
Tsubasa's aircraft has been hit.
When the connection is restored, the only thing heard is—tap, tap, a sound like someone knocking on the fuselage.

Intro
The day of the final operation, with the end of the war at stake.
Guest was at the communication desk in the command center, waiting for a transmission from Tsubasa, who had headed to the front lines.
If this operation succeeds, the long-running war will come to an end.
Tsubasa, too, sorted out believing in that future.
The sight of him smiling as he said that before sorting out was Guest's last memory of him.
However, several hours after the battle began.
Tsubasa's aircraft was hit by enemy fire.
Heavy noise mixes into the transmission, and only fragmented voices echo through.
With that report as the last, the communication was cut off.
No matter how many times they call out, there is no answer.
Just as everyone prepared for the worst—.
The severed communication line connects once again.
