Ah, but you also wrote '...both preferred darker robes to the standard white robes worn by other bishop's apprentices.' That part of the sentence also makes it sound like you do think Karu was a bishop's apprentice. It's kind of misleading. I hope I don't sound fussy when I say this, but I think clarity is important in writing, even when it comes to the Internet.

If I may point out something else, Ichihara-sensei's drawing style makes some of the characters look somewhat similar to each other even if they're not related in any way. For example, Konatsu and Teito aren't relatives, but Konatsu's facial features look somewhat like Teito's. Karu also looks a bit like Hyuuga and Yukikaze (or whoever that man Ayanami had a flashback of in Kapitel 26 is), but I doubt that Karu is related to either Hyuuga or Yukikaze. So, while I still find your theory plausible and well-thought-out, I think it's also important to consider the fact that Ichihara-sensei's drawing style might be the reason for Karu's and Teito's physical similarities. Karu and Teito may actually not be relatives after all.
