Meet Konata, an athletic and intelligent girl too, dedicated to her favorite primetime animes and 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 Konatas 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!
