Anyone heard about volume 14 coming out?

It have been quite a while since volume 13 came out.

According to back of the book, it says the first edition of volume 13
was published in April 23, 1996. (It doesn't seem that long to me
though)

There are already 25 chapters after volume 13, I really need to see
chapter 78 through 86. I got hold of subscription to Afternoon from
chaper 87.  I know I can see the glimps of stories in
http://www02.so-net.or.jp/~akira_i/amg/ but it isn't just enough....

If there is a kind soul out there who would bother to tell me how the
story went, and when would volume 14 come out, please reply.
