Another explanation could be that he's the real "K" and that BG9 was his creation or something. That would explain BG's origins and why he's the ninth.

I have a feeling that some of the Stern Ritter and Shinigami powers that have been mostly left unknown are going to be revealed in a flashback, like Robert's schrift meaning and Unohana's bankai. Bobby boy mentioned how Liltotto was too young to realize what Yhwach does to his subordinates he deems unnecessary, which implies that he's been there for a long time. So maybe we'll get a flashback to the conflict of 1000 years ago. Perhaps Shaz will be explained then as well.
