Negi Springfield is a typical ten year-old Welsh boy -- except that he's a mage, and an English teacher at an all girls school in Japan! In order to become a full mage he has to prove himself as a teacher and find suitable partners to aid him; but above all, he has to make sure that no one discovers his secret. Much to his dismay his secret is discovered on the first day by one of his students, Asuna. To prevent Negi from being punished, Asuna agrees to become his partner -- however she isn't the only one to find out. As time goes by more of his students find out his secret. How long can he keep his powers hidden when little by little all of his students are becoming his partners?
Layered with innumerable in-jokes and tailored to appeal to the fans Negima!? and Sayonara Zetsubou Sensei are part of the current fad for anime that speak directly to the more knowledgeable anime fans. Sharing the ubiquitous "in-joke" blackboard writings that are also a mainstay of Paniponi Dash!, and with the same constant verbal references as Lucky Star, these anime practically require a college-level course in Japanese popular culture and anime to understand. But if one of these is your thing, then it's likely that you'll enjoy the others, too.

F City, F Prefecture: the battleground where good and evil have finally chosen to decide once and for all who will rule the world…or at least that's the general idea! Neither side seems up for the task, as surviving the brutality of everyday life is enough of a chore. On the side of evil is the organization of Across, its only member the loudmouthed and abrasive Excel who struggles just to put food in her stomach; on the side of good, three disenfranchised, unemployed bachelors whose only pursuit in life is romance. Add in alien invasions, jungle warfare, and Mexican immigrant laborers to Japan, and this war doesn't seem likely to be ending soon!
Excel Saga and Sayonara Zetsubou Sensei are fast-paced, almost stream-of-consciousness, comedies. Both are marked by cinematographic in-jokes but, at their core, they are satires on the Japanese lifestyle and culture that take their assumptions to the extreme.
These series have plenty to offer fans of gag-based, self-referential comedy and those who enjoy black humor. So if you belong to either camp, there's always something to like.
