Kuroshitsuji
In Victorian-era Europe, a young boy loses everything he once held near and dear to a vicious plot. In his moment of death, he strikes a deal with a demon: his soul, in exchange for revenge. Ciel Phantomhive is now the head of the Phantomhive corporation, handling all business affairs as well as the underground work for the Queen of England. His new partner is a demon butler, Sebastian Michaelis, whose prowess as a butler is only surpassed by his strength as a demon.
The story follows the two along with their other servants, as they work to unravel the plot behind Ciel’s parents’ murder, and the horrendous tragedies that befell Ciel in the month directly after.
Pandora Hearts
To young Oz Vessalius, heir to the Vessalius Duke House, the perilous world called the Abyss is nothing more than a folktale used to scare misbehaving children. However, when Oz’s coming-of-age ceremony is interrupted by the malicious Baskerville Clan intent on banishing him into the depths of the Abyss, the Vessalius heir realizes that his peaceful life of luxury is at its end. Now, he must confront the world of the Abyss and its dwellers, the monstrous “Chains,” which are both not quite as fake as he once believed.
Based on the supernatural fantasy manga of the same name, Pandora Hearts tells the story of fifteen-year-old Oz’s journey to discover the meaning behind the strange events that have overtaken his life. Assisted by a mysterious Chain named Alice, whose nickname is “Bloodstained Black Rabbit,” and members of a clandestine organization known as “Pandora,” Oz begins to realize his existence may have more meaning than he could have ever imagined.

Kamigami no Asobi

Ao no Exorcist
Humans and demons are two sides of the same coin, as are Assiah and Gehenna, their respective worlds. The only way to travel between the realms is by the means of possession, like in ghost stories. However, Satan, the ruler of Gehenna, cannot find a suitable host to possess and therefore, remains imprisoned in his world. In a desperate attempt to conquer Assiah, he sends his son instead, intending for him to eventually grow into a vessel capable of possession by the demon king.
Ao no Exorcist follows Rin Okumura who appears to be an ordinary, somewhat troublesome teenager—that is until one day he is ambushed by demons. His world turns upside down when he discovers that he is in fact the very son of Satan and that his demon father wishes for him to return so they can conquer Assiah together. Not wanting to join the king of Gehenna, Rin decides to begin training to become an exorcist so that he can fight to defend Assiah alongside his brother Yukio. [Written by MAL Rewrite]
