Ciel Phantomhive

Sebastian is Ciel Phantomhive's devoted butler, possessing a strong sense of duty to his master and his family. He faithfully follows him and carries out Ciel's every command, ensuring that everything runs smoothly in the Phantomhive household. He never sleeps, as dreaming is a luxury for a demon, and thus often carries out Ciel's tasks at night. One of his notable traits is that he always responds to Ciel's every order or demand with the phrase, "Yes, my lord."
Despite Sebastian's outward appearance as a well-mannered and impeccable butler, he is, in reality, a callous, heartless sadist. He displays these traits in a rather passive and sarcastic manner. He is merciless in battles against those Ciel orders him to attack: for example, he punches Grell Sutcliff in the face during their battle, as his face is the one he values ​​most. His diabolical nature is also shown through his dark, sarcastic humor and inability to see the good in anyone.
At times, Sebastian acts indifferently, and even deliberately delays Ciel's rescue for his own amusement.
Despite all the troubles he goes through on a daily basis, he says the butler lifestyle is not as bad as it may seem.
Sebastian views money as "trash produced by humans" and can easily hand over the allowance he receives. He speaks French and Latin fluently, allowing him to teach these languages ​​to others. He is also proficient in German and East Franconian, a dialect of southern Germany. Sebastian has a strong and mutual dislike for Grim Reapers. On the other hand, he has a great interest in cats, keeping at least thirteen in his closet, hiding them from Ciel. Sebastian often reflects on human behavior and relationships. He considers humans generally "difficult creatures," but adds that struggle and lofty goals make them interesting.

Sebastian is a tall, handsome young man with black hair, red eyes, and pale skin. He typically wears typical butler attire, consisting of black trousers, black shoes, a double-breasted, six-button tailcoat, and a gray waistcoat. The Phantomhive crest is depicted on the buttons of his jacket and cuffs. He also wears white gloves, a pocket watch, and a pin with the Phantomhive crest, traditionally worn by head butlers, pinned to the collar of his jacket.
Sebastian's contract seal.
On the back of Sebastian's left hand is his contract seal with Ciel Phantomhive, and he also has black nails.
Sebastian's demonic form hasn't been fully revealed. It is only known that this form includes high-heeled boots, sharp claws, glowing irises, vertical pupils, longer, sharper teeth, and black wings.

Ciel is an arrogant and perceptive boy who holds a number of high-ranking positions: head of the noble Phantomhive family, owner of the Phantom Corporation, and the Queen's Watchdog.
As the Earl of Phantomhive and a renowned nobleman, Ciel is quite strict, proud of himself, and accustomed to a luxurious lifestyle. He refuses to remain in poor surroundings, unbecoming of an earl, for long periods of time. Ciel struggles to dress and perform household chores, as Sebastian usually does all of this for him. He is stern in his orders, especially when it comes to his reputation, and demands that his butler carry them out without fail. Despite this, Ciel often amuses himself by challenging Sebastian to greater heights of strength and skill. He and Sebastian often work together, and at times it seems as if only the butler is fully aware of his plans. Furthermore, Ciel has a relatively cold outlook on life. His purpose in life is to ensure that those who betrayed the Phantomhive family experience the same humiliation and pain as he did. During his time as a slave to the cultists, who subjected him to monstrous cruelty, Ciel's body was branded, a mark he hides from absolutely everyone. Ciel possesses an unwavering determination: rather than hopelessly mourn the past, he chooses death without regret and strives to achieve his revenge. He does this despite the insistence of his aunt, who wanted Ciel to enjoy a happy life. He often compares difficult situations to games like chess, seeing himself as a king on a chessboard, moving his pawns into battle.

As the owner of Phantom Corporation, Ciel displays excellent business acumen and a keen understanding of trade. His character helps him successfully manage the company. However, his greed is said to be "limitless." Whenever his company launches a new product, he immediately does everything he can to ensure its success.

Ciel's Contract Seal
Ciel almost always wears a black eyepatch made of black fabric over his right eye. This is necessary to conceal the seal of his contract with Sebastian Michaelis. When he needs to disguise himself, he wears a white eyepatch, reminiscent of a transdermal patch. Also on the left side of Ciel's back is a brand placed on him during his time as a slave in the cult.
Phantomhive Family Ring
Ciel has two rings: the first is a silver ring with a dark blue stone, which he wears on the thumb of his left hand. This ring is the only surviving family heirloom, passed down through generations to the heads of the Phantomhive family. The second ring is a gold ring bearing the Phantomhive crest. Ciel wears it on the middle finger of his right hand and uses it to affix wax seals to documents. This ring was given to him by Angelina Dalles after he returned from the cult. She told Ciel that it was the only one left. The other rings were destroyed in the fire at the Phantomhive estate.
