    Black Butler AU: A Devil’s Vow

    Sebastian Michaelis had spent three years believing his wife was gone. After forming his contract with Ciel Phantomhive, Sebastian was forced to separate from Destiny, the demon he had loved for centuries. They had sworn that once Ciel’s revenge was complete, they would reunite. But only two months into their separation, Sebastian’s connection to Destiny suddenly disappeared. He searched for her whenever his duties permitted, yet he found no trace of her—until Alois Trancy invited the Phantomhive household to an extravagant gala. There, dressed in the uniform of a Trancy maid, was Destiny. The moment Sebastian recognized his wife, his normally flawless composure shattered. He crossed the ballroom without waiting for Ciel’s permission and caught Destiny by her arms. “Destiny?” Her eyes filled with tears. “Sebastian…” His gloved hand rose to her cheek. “You’re alive.” “I never stopped waiting for you.” Before Sebastian could embrace her, Alois stepped forward and revealed the crimson-black collar sealed around Destiny’s throat. The enchanted collar suppressed her demonic powers and forced her to obey every command Alois gave. “I do hope you like what I’ve done with your wife,” Alois taunted. The candles throughout the ballroom extinguished as Sebastian’s eyes glowed in the darkness. “You have made a most regrettable mistake.” Sebastian attempted to take Destiny away immediately, but Alois ordered her to remain at his side. The collar activated, dragging Destiny from her husband’s arms and forcing her to kneel beside Alois. “Destiny,” Sebastian commanded softly, “come to me.” She tried. The collar tightened until blood appeared beneath it. “I can’t,” she gasped. “I’m sorry.” Sebastian took a threatening step forward, but Claude blocked his path. “Removing the collar by force will destroy her soul,” Claude warned. “Then you will tell me how to remove it safely.” “No.” Sebastian smiled coldly. “I wasn’t making a request.”

    Black butler AU: The Devil’s Bride

    As Destiny and Sebastian investigate the Eden Society, their marriage becomes the center of a supernatural conspiracy. Someone is attempting to create an artificial demon capable of consuming souls without forming contracts—and they require blood from Sebastian’s true form and the death energy within Destiny to complete it. Destiny must work beside Ciel despite distrusting his control over her husband. Over time, she becomes fiercely protective of the young earl, although she disguises her affection through threats, sarcasm, and secretly leaving enchanted knives beneath his pillow. Sebastian’s perfect composure also begins to slip. He becomes openly possessive whenever Undertaker teases Destiny, irritated when Grell calls her “a gothic goddess,” and merciless toward anyone who touches the red wedding mark on her thigh. Their greatest enemy eventually reveals that Sebastian’s contract with Ciel contains a hidden condition: when Sebastian consumes Ciel’s soul, Destiny will be dragged back to the Grim Reaper Dispatch and executed for desertion. For the first time, Sebastian must choose between completing a contract—and protecting the only soul he has ever refused to devour. When Destiny offers to surrender herself to save him, Sebastian reveals his terrifying true form and places her upon his throne of shadows. “I existed for centuries before I met you,” he tells her, his skeletal hand holding her with impossible gentleness. “Do not mistake existence for living.” Destiny touches the face beneath his skull-like mask. “And if Hell itself comes to separate us?” Sebastian’s snakes coil protectively around them as his crimson eyes ignite. “Then Hell will learn why demons pray that I remain a butler.”
