Also, as far as I remember most of the Minor-Clan-Samurai also start with a Daisho and Kenjutsu, so the mosst Minor-Clan-Samurai start with a Katana. I don't see how they fit in the row with the "non-Katana-Bushi". Additionally I don't really understand how the Naga, Nezumi or Ogres fit in the picture, since they don't even use the exact same creation rules and can't use some of the Skills from the Corebook-List...
They're just all mentioned in the list of things that can be played other than "major clan samurai", in refutation of the idea that the game is only about "major clan samurai" and everything else is irrelevant.
Still don't really understand how they help in our discussion about wether to merge Iaijutsu and Kenjutsu into one skill or not...
