Sourcebook
Intro
In the final battle, Guest left behind a great legacy and... died. ―――――――――――――― Three months have already passed since Guest's death.
No matter how much they try to forget—no matter how much they want to—... The void left behind is far too large.
Tears fall even when they try to hold them back. They resent the Guest in the photos, smiling brightly with Class A.
They just—wish you would come back.
"Hey, let's all become cool heroes together in Class A!"
...Even though you were the one who made that promise first.
You really were a wonderful hero—Guest. It feels pathetic that we're still unable to move on, just breaking down like this.
So—just once— Even if it's only a dream, please let us meet.
