Anyway, this drama is based on manga volume 5 and then volume 9,
skipping whole lot in between, which the OVA2 seems to be covering.
These days, the manga release rate is about one volume per year, so
I can't imagine more anime being made unless they change the voice of
Alpha. Besides, despite the effort, I find the anime lacking compared
to the manga. I guess I shouldn't talk about that until I review the
DVD.
Back to the CD, it's impossible for me to ascertain it without giving
myself an amnesia, but I think that if you listen to the CD drama
before reading the manga, you actually get more out of it. I say that
because I enjoyed the first two volumes of the CD drama a lot more
than Nonchan (Studio Neko-Han-Ten) did even though I was sort of lost
with the imagery. Thinking back, I might have enjoyed this CD more if
I didn't read the manga so far. I'm at volume 9. Volume 10 is coming
out next month (March 2003).
In the end, I highly recommend the manga and the soundtracks, but
not necessarily the CD dramas. I'll talk about the anime in my DVD
reviews.
