[Tiny spoilers] The entire plot is just so well thought out... But it doesn't really move Ciel forward in his revenge scheme. One thing I enjoyed was: a huge plot twist occurs in later chapters, showing just how well planned this manga is, but there are some arcs seem random but are in some way still enjoyable.. (The Circus, to cruise ship with zombies, a college, then a boy band?) The art style is refreshing - highly detailed and beautiful. I also love the Victorian clothing and styles... Each character has their own unique story and background - that's what I love, but side characters have littleto no development. Ciel doesn't have much character development, but further into the novel we begin to understand him and his actions better.
