When eating a chocolate cornet, which end do you begin with, the top or the bottom? Which side is the top and which is the bottom? For that matter, what is a chocolate cornet? The proper way to eat pastries is only one of the many everyday occurrences explored by the girls of Ms. Kuroi's class. Meet Konata, an athletic and intelligent girl too dedicated to her favorite primetime anime to excel in anything but otaku culture; Miyuki, the cute, bespectacled living example of moe with an encyclopedic knowledge of all subjects; Kagami, the bitter-sweet, tough but shy straight-man to Konata's constant teasing and pranks; and her younger fraternal twin sister, Tsukasa, a kind but air-headed klutz. Witness this study in the human condition as our heroines explore the unexplored in questioning the ordinary!
