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.
É da mesma autora,tem traços parecidos,personagens que de certa forma lembram os de Pandora Hearts, além de aparentar ter um enredo tão obscuro e complexo quanto.
