[@Weird Tales] Well, it's important to know your character's backstory because she's so unique.  With a character like Gin or Shin we don't need a background as much because they can be explained through story.  With Princess she has such a unique aspect of her unlike any Z-fighter that it would be hard to really add her into the story properly without any better understanding.  It would be like adding Pokemon into a war thread.  No one understands why that would be good or how to put it in unless you give Ash a backstory that fits the plot, or can be fitted in.  I hope that makes sense, I just woke up. XD
