Hmm, let's see...
Katekyo Hitman REBORN!, D.Gray-man, Loveless, Kuroshitsuji, Soul Eater, Death Note, Vampire Knight, In The End, Junjou Romantica, Godchild, Hana-Kimi, Air Gear
That's not all of them, but that's a fair few. My favourites are mainly composed of Shonen, Shonen-ai/Yaoi, and a few Shoujo titles thrown in.
