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.
