Georg von Siemens

Honorary director of Germany's Bamberg Bank and the guest of honor at a formal dinner. A distant relative of Her Majesty Queen Victoria and a guest. He visited the country to inspect British culture and technology, and at the queen's request, was invited by Ciel to be the guest of honor at the Phantomhive estate's formal dinner. Normally a strict and serious person, he has a very bad habit of drinking, causing trouble by making advances on Irene and Mey-Rin when drunk. After the dinner party, he is found murdered in his room, a locked room mystery, marking the beginning of the murder case arc.

In reality, he was induced by Grey to take a drug that put him in a state of suspended animation as part of a ruse. However, upon regaining consciousness, he was truly murdered by Grey. The queen's true objective was to prevent the strengthening of German military power by killing Siemens, and to pin the blame and responsibility on the Phantomhive family, as a penalty for disobeying orders in the "Noah's Ark Circus" arc (for not saving the kidnapped children).

The character is loosely based on the German banker Georg von Siemens.
