So many people were blown away in fact, that they've turned it into a full on franchise. And, without spoiling anything, the ending is incredible. The all have great personalities that bounce off of each other perfectly. Even the FILLER episodes are enjoyable because I just love watching what life is like in the Phantomhive household with Sebastian, Ciel, and the servants. The story arcs are some of the best I've ever seen in any form of media and there are no plot holes. Sebastian just doesn't give a single damn about the current situation most of the time and is an absolute bad ass. Sebastian comes close to being my favourite, however I just like Ciel a little more. He also has some of the funniest lines in the show. He is arrogant and is aware of it and is very pessimistic, but he has a reason for his sadness (his parents murder) and we get plenty of flashbacks revealing his backstory. All the main characters are likable and interesting and are well developed. Together they police England's criminal underworld and dispose of anything the Queen tells them to dispose of. Ciel makes a deal with Sebastian stating that when he finds the killer of his parents, Sebastian can have his soul. Ciel names the demon Sebastian and asks him to take on the form of a butler to help him as he is now the owner of the Phantomhive manor, previously belonging to his murdered parents. The plot is straight forward, young Ciel Phantomhive summons a demon to save himself from the torture he was being put through. The accents are exaggerated and are made to be extra posh, but they never ever annoy me.
It's the best anime dub I've ever heard, and since the show is set in late 19th century England, British sounding voice actors fit even more. It's also the only anime I've found that has a dub that's better than the original. It blends dark humour in with dark plots with the same anime charm that Fairy Tail and many others have. Sebastian is made the Phantomhive main butler yet again and he swears his loyalty to Ciel until the day lies become truth.Black Butler is my favourite anime for a reason. At the end, Ciel invites Snake to live in the Phantomhive manor as well. This experience influences Arthur Conan Doyle and he sets off to his career. For that, Sebastian managed to orchestrate the entire ordeal - do the Queen's secret task, clear the Phantomhive name of any possible murder accusations, and send a guilty businessman to jail. Ciel and Sebastian simply made use of this occasion, knowing Siemens would be killed either way, and framed Woodley, who deserved to go to prison. Sebastian admits and reveals the culprit's identity was known all along – it was Earl Grey, the Queen's butler, whom she had sent to kill Siemens, in order to disrupt Germany's financial stability, and at the same time, jokingly frame Ciel for the murder as a compensation for the accident with Noah's Arc Circus. The case is considered closed, but soon, Arthur Conan Doyle notices the inconsistencies in the theory and reveals the truth. The reverend also deduces that Siemens had jokingly faked his own death, but was killed soon afterwards by another guest – Woodley, who wanted to frame Ciel to prevent him from destroying his diamond business. Soon, it is found out that one of the murders was mistakenly done by a snake that was trained to go after Ciel's scent, later revealed to be sent by Snake from Noah's Arc Circus in an attempt to avenge his friends. Sebastian had "foreseen" his murder and the letter he had sent was addressed to reverend Jeremy Rathborne, calling him to investigate. The mysterious reverend Jeremy Rathborne then suddenly appears. It is discovered that Sebastian had entrusted Mey-Rin with a letter to be sent by an owl in the morning. Soon, another guest is found dead and everyone reassesses their alibis. Ciel comes to accept his death, after Sebastian refuses to revive. The guests find his corpse in the morning. He then visits the other servants, giving over his duties to them, and finally, bids Ciel farewell. Later that night, someone kills Sebastian. He is then confined to one of his guests – Arthur Conan Doyle, a novice writer. Everyone among the guests and the staff has an alibi, except for Ciel. The banquet begins and later, Siemens is found murdered in his room at the manor. The occasion is the arrival of a German banker, Lord Georg von Siemens. Her butlers - the Double Charles, come to the Phantomhive manor and orders that a banquet is held at the mansion. The Queen decides to test Ciel's loyalty once more after he killed the children, who were kidnapped by Noah's Arc Circus.
