Could someone tell me what this is about?! I read Shugo Chara. . .but this is kinda creepy. . .

The series is about 7 different bambole called Rozen Maiden, fighting in a sort of game named "Alice Game". Their creator, Rozen, looked after the most beautiful girl in the world named Alice. So he created the seven bambole to kill eachother in this "Alice Game."

Then there's one doll named Shinku, who wants the Alice Game to end, as she doesn't want to see her sisters dead.

... That's how it is, I guess. Haven't watched the whole series, so. .____.
