It COULD just be bad writing. Because I remember it was mentioned somewhere that Kamachi actually did not want the dragons to be included in the manga, but the mangaka insisted. So, he might have had a reason for not wanting to include them (like he's actually still finalising about what resides within the IB and the mystery behind it). This is not entirely impossible, as I believe Kamachi is doing the same thing with #6 of Academy City, where he said that #6's power was too strange and he didn't really know how to explain it yet in one of the afterwords (forgot which volume).
