Yes, I mean music CDs. Drama CDs might be kind of hard, although games could be possible.
On that note, one thing I forgot to mention is that I do know a couple people who can translate English to Japanese (like Masuo, the guy who did Pasu's comic), so even if you don't know Japanese, we can still produce your work. And if you're having a hard time coming up with ideas, I'd be more than happy to write a script given a few specifications. I want to release more bilingual comics, one way or another.
However, as far as more novel-like fanfics go, that's a bit iffier. It's not that I think they're a waste of time or unprofitable or even that much more expensive to print, but they seem to move slower than comics, and I only have so much storage space...
