Yea
Nope. We don't like her because she is simply annoying. There are also other female characters in the manga but none of them is annoying as her so we don't complain 'bout them. For example - The Green Witch. She is really cute if you ask me.
Also, I don't remember wnen but I think it was said that Ciel and Lizzie care for each other more like cousins than lovers.
Anyway, everyone has their own opinion and I respect yours Mine is this.
But I do agree Lizzie is skillful (=・ω・=)

i dont care how much you all hates Lizzie i just love her so muchhhh nad i dont even know whyyyyyy(╯°Д °)╯╧╧
