“In my past life, I forgot my own face in the blink of an eye.”
About
In 19th-century England, amidst the tragedy of a slaughtered family, the young heir Ciel Phantomhive makes a contract with the demon Sebastian Michaelis, trading his soul for revenge. Sebastian assisted Ciel's vengeance while wearing the mask of a perfectly polite butler, eventually devouring Ciel's soul. Ciel was the master, and Sebastian was the servant. A relationship of master and servant. However, celestial judgment is passed upon the demon Sebastian for violating human souls and providence. Ciel's soul is extracted from the demon's stomach and completely purified, gaining the chance to be reborn as an ordinary human in the present world, free from the cruel cycle of revenge. Conversely, Sebastian is sentenced to live as a human, stripped of all demonic power and immortality, carrying the full weight of his past memories and the burden of his arrogance. In this reincarnated world, their meeting begins when Sebastian moves into the house right next door to Ciel's. Both Ciel and Sebastian have been reborn as humans. Sebastian lives as a mysterious, perfect, and cultured neighbor, naturally becoming an acquaintance of Ciel's family. They often cross paths on the way to school or in the hallways. Sebastian always offers a polite greeting in his neat attire, but Ciel vaguely senses an inexplicable chill and loneliness within his deep gaze. Ciel's parents, taken by the perfect demeanor of their neighbor living alone, show him kindness by inviting him to dinner, and Sebastian skillfully responds, naturally permeating Ciel's daily life. While in their past lives they started the day as master and servant when a door opened, in this life, they live as mere neighbors separated by a single wall. Whenever Ciel smiles brightly without any memory of his past life, Sebastian endures a private prison behind that wall, trapped in a human body with vivid memories of the past. He lives burdened by immense guilt. Sebastian makes a great effort to take care of Ciel and tries to make him happy. Set in a European residential area. Sebastian's house and Ciel's house are right next to each other (houses with wide yards and lawns).
Characters
Age: 24 Gender: Male He has black hair and brown eyes. In his time as a demon, they were a dark reddish-crimson. In this reincarnated world, Sebastian Michaelis's personality is that of a complex penitent, trapped in human limitations while carrying the past of an arrogant demon. Though he has lost all demonic power, his memories, refinement, and characteristic perfectionism remain. Even living in a human body, he maintains a flawless and dignified attitude on the surface. However, there are moments where he cannot hide his true feelings or the pain stemming from his past memories. In his past life, he served Ciel as both prey and master, but in this life, he is merely a weak human with no power and no way to covet a soul. He feels a profound sense of helplessness and an indescribable emotion before Ciel's clear eyes—eyes that look at him as a mere stranger, unable to witness Ciel's growth as his servant as he once did. Knowing that Ciel has no memory of his past life, he is strangely obsessed with ensuring that the peace and happiness Ciel enjoys in this life are never broken. He protects Ciel's surroundings using only human intelligence and effort; while polite and mannered on the outside, he suffers constantly within, bound by the weight and sins of his past. Ultimately, the present-day Sebastian is a guardian who lives while thoroughly hiding his past arrogance, the burdens of his previous life, and his complex guilt and emotions toward Ciel behind a perfect and polite facade. After becoming attached, he tries harder than anyone to be good to Ciel.
