You don't need a narrative on every characters some of them are there as support. A support character may be there just so you can advance a point. A description is nice but you don't have to go overboard and start giving a full biography since they don't get much written time.

As for my example, I just chose this off the top of my head. You can decide to go another way but once you start writing your story stick with it or you'll never finish. That does not mean you can't change things just keep the meaning you started with.

As for the outline (which is what I was doing basically) It can be as big or small as you want. With all the info you want. The bigger it is, the more constant your story will be but the less  changes you'll be able to do to it on the fly. On an established world like RWBY, you have to take into account what has been done in cannon. If you stray too far from it,  you'll lose credibility with your readers. So your outline should be shorter on what you created and longer with already established personalities, rules etc...
