Set for Oct. 30 release
HakuYou 白い翼を継ぐ絆 (Bond of the White Wings)
......If only HakuYou and Migawari would be released at around the same time rather than being a month off of one another. (Both have vols coming out ~every 3 months right now. ^^; ) At a guess, HakuYou should have another SS vol coming out soon as well. With the next Cobalt, there will be 5 SSs that have come out in the mags that haven't been released in a vol. I'm seriously falling behind. >.<;
Otherwise, there's an interesting comment in the Akuryou thread on 2ch as to why GH stopped after Akumu. Will comment more if any actual detail comes out about it.
