first year students (k-on!)
Generic first year students in K-ON!! are identically drawn with beady eyes and permanent blush stickers, and their hairstyles are the only way of telling them apart. Examples seen in the second season of the anime include two members of the Jazz Club in episode 5, two members of the Akiyama Mio Fan Club in episode 7, and three girls who wanted to get their picture taken with Yamanaka Sawako in episode 10.
