User blog comment:Sosuke Aizen008/Who is the most powerful in stern ritters?/@comment-1268838-20130924203012

I doubt that the letters really have anything to do with how powerful the Sternritter are, even with Yhwach and Jugram happening to occupy the two highest letters. It would be a little ridiculous if the Schrift somehow managed to be both an abbreviation for their signature abilities and an indicator of the order of their power.
