I guess some people didn't like Yasu, the baby Natsuhi threw off a cliff and miraculously survived, grew up and became Shkanontrice. Also in the miracle kakera where she accepted the baby, they became Lion, the heir to the Ushiromiya family. Also Kyrie and Rudolf kill everyone because they are now evil. And Shkanontrice blows up the house and errbody dies. I think. I've forgotten.

In EP 8, which people hate much more, everyone dies and Battler survives but gets amnesia and the whole story is him trying to make sense of his memories. For example, Lamdadelta is a cake.
