Miwa Sakai has published so many series over the years, that it is not surprising that there are several "best of" collections of her works. Each volume contains random chapters of her various series. They are sort of like sample books :D Some of these volumes have a theme, while others are just general collected stories. Most of these volumes are all done by Sakai-sensei, while a few of them are collections of works by several authors, with a story or two contributed by Sakai-sensei.
