Pandora Hearts

Both Kuroshitsuji and Pandora Hearts have a similar darker tone to the plot, and both also mix this with a small dose of comedy. Though the subject matter is different, both are also based on the supernatural. If you liked one, then try the other.

If you liked Kuro Shitsuji or Pandora Hearts, you'd more than likely like the other just as much, or perhaps more. They both contain a small amount of action to feed your inner action-hungry self, but are both more themed to a more mysterious, darker tone, and contain both mystery and supernatural.

Another thing to note is that they both have similar clothing, which is a plus, and that every character has a unique, definable personality. 

Both anime feature supernatural creatures. They also feature a boy dealing with his past, and the servant/master relationship is important in both as well. The settings are similar, and the tone and characters remind me of each other. 

Pandora and Kuroshitsuji  have the same felling, using a young boy as principal character. And actually the boy in both cases has a servants with weird powers.

I pretty sure that if you like one you will like the other..

Kuroshitsuji and Pandora Hearts have the same tone as well as similar characters. The two shows give a serious plot with strong willed young protagonists who are both accompanied by a supernatural being through a contract.  They also share good comedic relief, if not entertainment, plus nice art and animation. If you enjoyed either Kuroshitusji or Pandora Hearts and would like to watch something akin to it, check the other out.

Having practically the same protagonists and simmilar definition of life and death, along with all characters that are not human, including shinigamis, demons and simmilar, relying on simple rules that settle the question of using the abilities of a demon (Kuroshitsuji) and a Chain (Pandora Hearts) without harming the vesel, a.k.a. the contract, and yet another also for the fabulous artwork and music, the mood of one anime is incomplete without the other. So, if you've liked one, you're most definitelly to like the other one as well.

Each of these series are fairly dark, center around a kid that has lost his parents, and contain many extremely powerful fighters. With a good mix of darkness, action, comedy, and a bit of supernatural things in the works, these series are a good fit.

both anime's were somewhat  depressing at times and also funny  at times and the main characters reminded me of each other

Both main characters in this series are in master servant relation, both are boys from royalty making contract with some demon. The end of it always means death to human, however they developed a bond and neither human or demon want to see each other dead.

Watching it you can find some similar characters, like white haired sweety-tooth guy witch another side to him.

And if above is not enough for you there is always nice art and animation in each of this series :)

The one show that reminded me the most about Pandora Hearts would have to be Kuroshitsuji. Maybe it is the mix of old world society and the supernatural. Or it could be the similar themes combined with the concept of a magical contract binding two people together for a common goal, but these two shows have a lot of similarities and I think if you enjoyed one you would find yourself enjoying the other as well.

Art style very similar, delicious occult theme.  Dolls!  Fetishes!  Creepy undertones in both series.  For example when Gil holds Oz to activate his powers and the romantic tension between Jun and Shinko in Rozen Maiden.  If you can get over the doll fetishism both are solid fantasy serieses.

Thematically the two anime also have a lot in common.  They both include european themes of soceity and nobility; both utilize victorian wardrobes, and both could be described as darkly romantic.  Alice in Wonderland is another theme that interweaves both.

Heterochromatic (having different colored eyes) makes an appearance in Rozen Maiden with the fan favorite Suiseiseki and in Pandora Hearts in the evil and insane Vincent.  The relationship between spirit and medium is explored with a slight attitude of masochism, the spirit having to "drain" the medium's energy in order to battle opponents.

After watching PH, the idea of having a "contract" and "medium" really sounded like RM to me.  Although there's a huge plot difference, the idea of having strong female leads really appeals to me.  Both Shinku and Alice shine on the screen and both of them boss the male protagonist around like no tomorrow. 

In terms of genre, PH is a lot more mystery focused and is a non-stop roller coaster of questions after the first bump.  RM is more slice-of-life focused (especially in season 2) and although there's barely any real plot development, the characters carry the show well.  However, both anime involve a deep history between the characters that's revealed a little at a time.  It's this fact that keeps things interesting in the present.

The setting of each of these series seem to be very similar, involving another dimension and fighting with some sort of familiar type thing.

D.Gray-Man and Pandora Hearts invoke the exact same kind of atmosphere of twisted childhood themes warped with plenty of fantasy and action. In both the premise is almost identical: people on the brink of despair seal deals with supernatural creatures that are supposed to help but that turn out to destroy those who summon them. More, the main characters are involved in the conflict via personal issues and with the help of a vaguely religious-like organization. The band of friends that gather around the hero is another common feature of these better than average shonen titles.

If you liked Pandora Hearts, it's a safe bet that you'll like D.Gray-Man too. Because in both series the "flavor", the art is very similar, fancy outfits, toylike monsters and all. Also both series involve fighting with inhuman monsters, both has some sort of company set to research the monsters' power. Although I liked character development in Pandora Hearts more, D.Gray-Man isn't lacking in that area as well.

To sum up both series give the same feeling - without repeating each other, and D.Gray-Man is pleasingly longer.

When I first started watching Pandora Hearts, D.Gray-man came to mind. Both of these animes are about fighting supernatural creatures from the abyss and have a really dark atmosphere that might creep out some of you. The twisted "childish"-like art is just scary sometimes. In both Pandora Hearts and D.Gray-man the main protagonists are involved with what appears to be a religious-like organizations, in D.Gray its the Black Orden and in Pandora Hearts its the Pandora, which helps the main characters along the way, but also have their own selfish goals. Both Allen and Oz have a supernatural powers, which they improve throught the episodes to protect their closest ones and find their own path.
