This is for the manga section.
I can think of 2 new series and a general suggestion.
"Lovely complex" is a relatively new manga from Shoujo Beat. It's a comedy romance where the main guy, Otani, is about a head shorter than the main girl, Risa. They usually make insults toward each other such as "Amazon," "Shorty," and so on which cracks up everyone else in the school. As the story progresses Risa begins to have feelings for Otani but she still sees themselves as the comedy duo of the school.
"King of Thrones" is also new. There is a deadly virus spreading around the world called the Medusa virus which pretty causes your body to solidify and crumble. A lottery was done and the chosen people who are infected were sent to an island that was transformed into a research lab to find a cure. Everyone is put into a cryogenic state until they can find a cure. The capsules suddenly reopen and everyone sees the whole lab has been covered in thrones and vines with monsters roaming around. Those that are left must find out what is going on, how long they've been cryogenically frozen, and if there is a cure. At the same time, they have the Medusa virus to worry about. A horror/survivor story for mature audiences.
My other general suggestion is recently I noticed some places carrying.... I'm not sure what to call them but they are large books of series that contain 3 volumes of storys. I've seen some for Negima, Tsubasa, and the one for RayEarth contains the entire series. And they're cheap too. I would recommend the RayEarth one just because that's such a old manga and the original individual manga is out of print.
