I need a really good anime.. These are the ones I have watched..?

WOW, you certainly love anime, don't you? One of my all-time favorites is "Hetalia: Axis Powers" It's broken down into 2 seasons, which consist of about 20 5-minute episodes each. It follows history a bit, but doesn't have much of a plot, really. Nevertheless, me and my friends find it hilarious! Also, a lot of my friends enjoy "Black Butler". Though I haven't seen it yet, I heard it's very good. Lastly, one of my friends likes one called "Higurashi". It's very gory; lots of blood and murder, if you like that kind of anime. Good luck and happy watching!
