~My Answer~
1-Fafner In The Azure : Right Of Left (OVA) : This OVA Is the best thing I've watched (it was better than the main series) what i like about this ova it's because the story is Awesome and mystery and i liked the main characters Yumi And Ryou and it's more different than the main series it's more cooler although the ending was Sad but still it's my fav OVA....
So What's You Favourite?
