Aside from the four main characters of this show (Konata-chan, Miyuki-chan, Tsukasa-chan and Kagami-kun), WHO IS YOUR FAVOURITE CHARACTER?

Mine, has got to be Konata-chan dumbass father & probably the workers in that one bookstore Konata
 visits (=゜ω゜)

those guys are just too hilarious (((( ゜д゜; ))))

OHHHH and probably also hiyori-chan, that one girl who is a dōjin artist and drew a yuri doujinshi, in which featured yutaka-tan + minami-kun~!
