Suzumiya Haruhi no Yuuutsu illustrated by Tsugano Gaku.
Suzumiya Haruhi is an adaption of the novel about Suzumiya Haruhi by Tanigawa Nagaru. I haven't read the manga but i feel that the Anime is the same since they both are adaptions. This anime would seem like a comedy at the start and is kind of like that throughout, but it really has a great philosophical theme which i really love.
On the first day of high school a beautiful girl named Haruhi Suzumiya introduces herself as having "no interest in ordinary humans". She asks for any aliens, time travelers, sliders or espers to join her. Watching her weird behaviour is Kyon a boy who sits in front of Haruhi and is the only person who talks to her. Commenting on Haruhi's joining every club in school and then quitting Kyon unwittingly gives Haruhi an idea to start her own after school club. Thereafter Kyon and several others find themselves literally dragged into the Save our world by Overloading it with fun Suzumiya Haruhi's Brigade (the S.O.S. Brigade for short).
This anime have been very popular for a short manga/anime and it seems that many people want more of it. I doubt this possibility though but they can hope i guess. although the main popularity has started to die down it seems its not completely dead yet seeing as there recently was released a drama CD.
i would really like to read the Suzumiya Haruhi novel sometime. since i really enjoyed this Anime. This is an anime you really should watch. And this is not like the no name mangas i usually write about, this one is really popular too. But i kind of belive that most people just see the comedy in Suzumiya haruhi and not the very deep story behind.
