Like a bit of a homage to the novels, all of these starts off with a page or two of dialog. It’s actually a pretty nice way to fit in some back-story while still maintaining a good tits-no tits ratio for the pages.

Vol. 1
Sena promises she’ll introduce Kodaka to a potential friend, but in return she wants to play around with Kobato. Sena isn’t willing to compromise when it comes to her demands, so Kodaka suggests they’ll solve their dispute with a chicken race. Basically it’s a number of dares, and the first one to back down has to listen the the other one.

Vol. 2
Everything that could be considered story in this book is covered by the first two pages of dialog (lots of text in this one), and then it’s just one long sex scene. At least it has a serious message: It’s important to have safe sex… unless you’re out of contraceptives.
Then it’s not so important anymore.
