Okay, I decided to give my system a check on a known rank. I can't think of Raising certain aspects of Hayate's stats higher than they are right now, so I decided she's getting a bonus because of her very high leadership qualities, and her magical power qualities. Oh, and to make things evenly rounded off, I added one more rank above triple S. Not that anyone makes that rank...
Comments, suggestions?
EDIT: Non-conventional ranking...
