アナーキー・イン・ザ・JK

This one volume manga focuses primarily on the daily life of a group of five (mostly) high school girls. Some of them have unusual qualities, like a glowing butt or a single cyclopean eye. The girls nevertheless have a fairly normal and comedic daily life, including stuff like going to family restaurants together, joking about sex, and talking about boys. (Source: MangaHelpers)
