I thought I should mention that Umineko no Naku Koro Ni anime has started airing and we're at episode 2 right now. You can read the large summary about it on page 87.
You can watch the opening subtitled through this
link Some kind person has also uploaded the first episode to YouTube.
Throwing in some scenes from it, like the Golden Witch's portrait
Best mother of the year award goes to this woman.
I recommend watching from 4m 30s up to 6m 36s. A wounded heart is the best ground for the witch to sneak in.
My only regret is that the first major corruption stuff is 10 or so episodes away and the next major corruption should be around episode 20 or something. As the island becomes more corrupted we'll get to see the 7 sin sisters and other demons that assist the Golden Witch.
