Why was called Weaponry in the first place?
Because the story's main character was Rebecca at the time. And she was built as a weapon. The story had no special meaning, and lacked in environmental designs. Now that I'e gave it a bit more meaning/message to the story, some things had to change. I merged two characters into one, and so now the story is not only about Rebecca, it's also about Yuw and Ching.
