I'm sure this is due, at least in part, to the fact that it was never (to my knowledge) translated.
It's hard to rally properly around a subject that you understand at most bits and pieces of it.
... which made me go randomly check what I DO have stored on the dramas, only to find that my links to an old Japanese El-Hazard site were broken. (As it unfortunately happens... most of the older El-Hazard sites, even in Japan, are slowly dying off one after another.) Of course, I apparently foresaw this event, as all of the html's I needed I had already locally stored in the "radiodrama" directory. (Of course, thank God, there's always the good ol'
Wayback Machine otherwise.)
If someone with a good knowledge of Japanese were to make an English translation of the Radio plays, that would be a real treasure.
And while they're at it, do the other CD dramas, too.

I'd love to have all of that stuff well documented. Though, of course, that's kind of just wishing on a star. But as long as I'm wishing, let's even have it performed vocally by the English cast after it's translated...
