@Ryl - not to disagree completely, but I dont think its the way the characters are presented (like the complex web of relations that you illustrated) that makes this show work. Its because it creates a realistic and familiar atmosphere, that is completely the opposite of other shows that tend to delve into fantasy and impossible situations too much. The jokes used in Lucky Star are something that people can relate to, and maybe even used themselves before. That said, I completely agree with your statement in bold, and I would just like to add - The Lucky Star world IS the real world
