Bunkasai! You just have to have one. I can't seem to remember, and
I'm too lazy to open up the DVD box, but I'm pretty sure some form of
bunkasai story was animated. There are actually multiple bunkasai
stories, which I'll get to in Nanaka 6/17+ review.
Then we have a short story in which Nanaka goes into (or dreams of)
Domiko's world. Again, I can't remember if it was animated, but I do
remember that it was in the CD drama. Hmm, I wonder why I can
remember CD drama better than the anime even though it's been longer
ago since I listened to the CD drama. I keep saying, CD drama was
better casted.
