It was midafternoon in Tokyo-3 when a knocking came at the door.
The person knocking didn't try the bell; they knew it wouldn't work.
Not satisfied with waiting, the person on the other side opened the
unlocked door. The door squeaked loudly on its ungreased hinges. On
the other side stood Ritsuko Akagi. After pushing the door open wide
enough to admit her, she slipped inside and let it close behind her.
"Rei?" she called out, stepping into the dirty, unlit apartment that
was Rei Ayanami's home.
