Something that bothered me while watching Azumanga Daioh is the way that its main characters always seemed to contrive ways to all hang out together, even when it didn't make sense for them to be there. Azumanga Daioh has a large ensemble cast of entertaining personalities, each with their own sets of relationships and friendships among each other. While all of them are in the same class together and generally get along with each other, not all of them are actually friends with each other. Tomo and Koyomi were friends before the series started and generally have the closest relationship of the bunch. Osaka and Chiyo are basically outcasts who stand out from everyone else (the former for being from Osaka, and the latter for being a child prodigy, plus they're both generally adorable weirdos), so they quickly formed a close bond. Kaori has a crush on Sakaki so they're together on occasion, and Yukari-sensei and Minamo-sensei were also friends before the start of the series so
