AZ 2
KuroBasu 3
Assassination Classroom
The Rolling Girls reminds me oddly of Kill la Kill, and I haven't even started Isuca or Soukyuu no Fafner Dead Aggressor orz
Though Brothers Conflict, New Prince of Tennis and Blood & Soul (!!!) OVAs look interesting as well.
Blue Uru is by Gainax and Hana to Alice... so many sequels.
