Marifune-kun:
Looking at your list, you seem to like a lot of action shonen, so recommending off of that (and yes I do see 1-2 slice-of-life and one of the most male-oriented shoujo stories out there)
First off, seconding everything ampzz recommended. (still, your reading seems ratehr light, so I am probably not going to name any darker series like Akumetsu)
My recs:
1/2 Prince
Aлёша!
Denpa Kyoushi
Iris Zero (you can almost call this a school based toaru clone)
Medaka Box
Oto x Maho
Siesta (another shoujo that appeals to a male audience)
The God of High School
Watashi no Mesiah-sama
Witch Hunter
World Embryo (If you liked Alive, this is similar)
Zippy Ziggy
There is some Korean Manhwa in there, but I don't think you will mind. If you or someone else ever reply to what they read and liked in this thread so far, I can give further recs.
