I am aware of how Kitsune in traditional mythology gain their tails.

however, unless I missed [url=http://highschooldxd.wikia.com/wiki/Kunou]Kunou[/url] being 900 years old somewhere, we can assume power = number of tails or at least, possible potential power.

But y'know, that's why I am asking xD

I do want her to be a nine-tails, and if she can gain more later after someone kicks her lazy butt into gear then that is fine with me. She can have two or three to start with. If not, then I would rather her have nine.
