In terms of the Elizabeth art, she changed dramatically with the Campagnia arc where she's in full color with the beautiful, Cher see-through dress complete with little boobies now. She has a prettier face, turned up nose, and long eyelashes. Now, too, she's a master swordsman. Those changes in the art as well as the character are radical.
In her pre-Campagnia existence, she literally attacks Ciel every time she greets him. One time she swung him round and round like a centrifuge. It was violent but funny. She's hysterical over the wing of the mansion mey rin, bard, and finnie destroyed so she must waste Ciel's day with the taylor and new clothes for Ciel and herself. She comes to the Phantomhive mansion uninvited when Ciel isn't home at least three times. She takes over, decorates, throws her weight around with the servants, and acts like a spoiled brat. She throws huge tantrums. She's pissed off when Ciel won't eat the cake she got for him. When he refuses to wear the ring she bought, she destroys his priceless, head of household heirloom ring. In the anime, she almost drowns Ciel, but that was second season so it doesn't count. In the Campagnia Arc, she refuses to take off her frock so she doesn't drown, pitching a fit and endangering both Ciel and her life. Next to Elizabeth, Mei Rin looks like Saint Joan of Arc.
I didn't look back at the manga for any of this (couldn't be bothered). It's all from memory.
come on, kuro. I obviously read the manga. I read the damned manga when it first came out. It was really short back then. I waited years. I read it this year in January. Since then I've read it twice and I go back now and read various parts I like. I'm still very much involved with my Kuroshitsuji obsession. I'm not new to this manga, and I'm tired of being accused of that. I'm probably one of its first readers.
Of course I've seen the anime. The first season of the anime, book of murder, circus, and atlantic follow the manga pretty closely.
How bout you? Share your boring history of how many times you've read the manga etc. Your turn, kuro, come at me, dude.

Just as Elizabeth became strong and beautiful, she turned on Our Ciel.
