I found summaries and a few photos of these two chapters (+bonus) from an Aki fanblog (mushroompie @ wordpress) and was just wondering. Personally, I think it might be because these two chapters were from the Kurofune ZERO magazine instead of the published volumes and so they weren't scanned but anyone's guess is as good as mine.

Anyway, just a little sad that this manga got so unceremoniously axed especially when some character backstories were finally beginning to be revealed after only some of the vaguest most cryptic clues as to how they're connected and their motivations desires goals etc etc. Guess we'll never know now 😢
