Really liked 'Wolf Girl and Black Prince'. There is a lot of potential there. The main character's ability to get herself into hot water is amusing.
Haven't decided if I'll keep watching 'Trinity 7' or not. I read the manga for awhile but, despite liking some of the character quite a bit (ninja girl is awesome), it's still a guy-with-massive-untapped-potential-surrounded-by-a-harem anime.
'The Seven Deadly Sins' is a lot more imaginative. Hawk is wonderful and I'm a huge (no pun intended) Diane fan. Heck, all of them are awesome. I'm looking forward to this in anime form. It's like a combination of Berserk and One Piece, as crazy as that sounds. Also, Elizabeth is excellent eye-candy.
