Neither was Schwarz Bruder. If you're Japanese and in the 90s, it makes as much sense as Chibodee Crockett.
They just didn't think or care much about the future palatability of the show.
They also dropped a massive fucking amount of hints throughout all of his appearances that he was, in fact, Kyouji. Pretty much everybody but the show's characters were painfully aware of it, even if they didn't know German.
There's also the fact that by itself, Schwarz Bruder doesn't mean shit. Who knows, maybe he's the "black" member of a brotherhood of German ninjas and there are red and yellow members too. It only makes sense after the fact.
I found one but it smells like hamburgers

I went in unspoiled (miraculously) somewhat recently and I figured it out within like two episodes after his introduction. Now, admittedly, I do have a pretty good ear, and I did watch it all in one weekend; there's a good chance that I wouldn't have remembered what Kyoji's voice sounded like watching it weekly on toonami as a 6yo. But I also watched through all of Speed Racer in middle school, so I was suspicious at just how hard Imagawa was shoving that Racer X dick down my throat.
Except it didn't. The show intentionally made it seem like the twist was gonna be Kyoji as a red herring for the real twist about it really being a robot. Did you even watch G Gundam?
