With a drama CD?!? Say what?
Edited to add the following:
Okay, apparently, they've gathered the cast and staff of the anime series together again to include a drama CD with the comic. First part comes out Summer '09 and the latter part in 2010. The title is "The Forgotten Children" which would mean it's the abandoned school house story (sic the current manga story).
Nifty. The thing that I'm not sure about is the price of the comic. The price that's listed was Y440 which is not far off of the normal price, so it might be that there's a different special comic release with the CD drama. (As much as I'd love to think that the Y440 version will include the CD, I tend to be a bit more jaded than that. ^^; ) In any case, I'll keep an eye out for manga release updates and for updates to this site (they haven't updated for the Aug manga release yet) and will post once I know more. ^_^
