Ok I see some errors here as well, kid. Let's exploit them shall we?
1. There is no way for you to have three soul weapons at once upon your rank nor there is any abilities upon what each one does. You can only have one soul partner for now (Unless Maze or Khrona approves you otherwise) until you actually improve on yourself and your soul partner as well. Take a class or ask one of the higher ups in the village to help you with that.
2. The storyline is rather....interesting, but as usual you gotta edit it as well to only just having one soul partner (Once again, Maze or Khrona approves of this otherwise.) and how you met up with her.
3. You probably will have to speak to Maze or Khrona into getting your soul weapon first to make it official.
