Eh, I'm not into Shonen stuff, but I seriously suggest you try Zero no Tsukaima - I have the whole first season in Japanese (Manga) - and all four seasons of the Anime in Japanese with English Subtitles.
Other than that, try Soul Eater - it's got a lot of Shonen-style action value, but the Manga is extremely Ecchy...
