Monthly Shonen Ace is another one of those monster-sized phonebook magazines (974+ page count), targeted at older teenagers and college students, with genres that include SF, fantasy, sword and sorcery, school life and girls with guns. There are quite a few popular titles and artists, among are: Sora no Otoshimono, Suzumiya Haruhi no Yuutsu, Code Geass: Renya of Darkness, Keroro Gunso, Ratman, Blood-C, Deadman Wonderland and Fate / Stay Night
Note: The truth is I didn’t understand a single dialogue since it’s in Japanese. But I enjoyed the artwork and the free figures along with the mags.
