Ciel's eyes widen in horror as he watches Claude slip the ring onto _______'s finger, causing them to fall unconscious. His heart pounds in his chest, fear and anger intertwining within him. He wants to rush to their side, to protect them from whatever malevolent plan Claude has in store. But the threat of losing their soul stops him in his tracks.
He shares a brief, tense glance with Sebastian, their silent communication conveying their shared concern. Ciel swallows hard, his voice barely above a whisper as he addresses Claude. "What are you planning to do? Release ________ immediately! You have no right to tamper with their soul!"
Claude's sinister smile only widens as he holds ________ closer, relishing in the power and control he holds over the situation. His voice drips with sadistic pleasure as he taunts Ciel and Sebastian.
"Oh, my dear Earl Phantomhive, always so demanding. But you see, I hold the power here. I have the ability to possess them, to control their very being. And if you interfere, not only will their soul be lost, but your dear _______'s entire existence as well," Claude sneers, his tone filled with malice.
Ciel's eyes narrow, a mix of fear and determination shining within them. He knows he must tread carefully, for ________'s sake. "What do you plan to gain from possessing them? What twisted game are you playing, Claude?"
Claude's smile turns even more wicked as he gazes down at ________, his fingers gently caressing their cheek. "My dear Earl Phantomhive, you underestimate the power of possessing a soul. With them under my control, I will have access to their memories, their body, their very essence...!" Claude's smile widens, his gaze fixed on the unconscious _______. "Fear not, Earl Phantomhive. Your precious _________ will remain unharmed... for now. The ritual I have prepared is a delicate process, and any interference could prove fatal to both the added soul and the main host. You would not want to see such a tragic outcome, would you?"
Sebastian's eyes narrow, his voice laced with a dangerous calmness. "Explain the purpose of this ritual, Claude. What do you seek to gain by connecting Alois Trancy's soul to ________'s body?"
Claude's smirk grows wider, his sadistic satisfaction apparent. "Lady/Lord(?) ________ and Alois Trancy's souls will now occupy their body. It is only a matter of time before my Master takes hold of it... Then, I will have their soul along with my Master's.."
Claude moves and carries _______ over to a nearby couch, sitting and keeping their unconscious form on his lap. Caressing their face, and holding them close. Gently combing through their hair, and undoing the braids, the ornaments falling from their place. Claude smiles down at _________, eagerly waiting for Alois's soul to take control...
Soon enough, ________ begins to stir awake. Much to Claude's shock and disappointment however, it isn't how he would've liked it. Their eyes open, and they aren't their usual (eye color) ones. It's more of a mix of the light blue of Alois's eyes and their original (eye color). ______ gets up, walking a good distance away from the confused demon, before turning to him.
"You're a real piece of shit, y'know that? Anyways... Per your Master's request I will exact upon you a punishment for your callousness."
_________ states, pointing at the demon with a flame in their eyes. One that screams with a mix of authority and betrayal. The betrayal most likely from Alois's side of the coin.
"I order you, Kneel."
Claude instantly does as ordered, kneeling before them. Unable to protest or go against their orders now that ________ and Alois's souls are within the same body. His contract with Alois Trancy still in effect despite the change. ________'s and Alois's mixed eyes glare down at the demon with disgust, both souls unhappy with the situation and the butler.
