Lucky 星, つ星 is one of those anime's that fit in the school category as the characters are Konata Izumi, Kagami Hiiragi, Tsukasa Hiiragi and Miyuki Takara, these characters are the main characters but mostly Konata Izumi is the main character in my opinion, these girls go through high school as フレンズ sadly Kagami was in separate classes then her フレンズ but this was the best アニメ I ever seen so far anyways Konata was the アニメ freak out of the フレンズ she loved cosplaying and マンガ also playing dating sims, Miyuki is the calm one out of everyone she wears glasses due to she hates anything to close to her eyes like contacts または water, Kagami is well a girl that is mostly serious and of course does her homework (( I never do mine half of the time :P )) anyways last but not least Tsukasa she is the twin sister of Kagami she is like Konata cause she copies off her sisters homework and she falls asleep when ever studying anyways this is my review I recommend to see it.
