Pandora Hearts, Vanitas no Carte Recommendations
It's by the same author so the feelings and atmosphere around it are very similar. Some characters are also very similar both in looks and personality with some of the Pandora Hearts characters. I also tend to believe they both happen during the same time period aka the 19th century basing myself on the clothes, just that Pandora hearts happens in England while Vanitas no Carte in France.
Manga by the same author as Pandora Hearts, Mochizuki Jun. Though Vanitas no Carte is noticeably darker and more mature, it explores similar themes as Pandora Hearts.
Sorry for bad English, I used google translator to write this.
It is the same author, has similar traits, characters that somehow resemble those of Pandora Hearts, and appear to have a plot as dark and complex as.
This is Mochizuki's new work after Pandora Hearts with Vampires and Steampunk. The story has many twists and has the same tone and magnificent art as PH. Basically its her new work. Read it.
It has a very similar vibe to both manga.
