That Butler, Isekaid (Modern!Reader Insert)

That Butler; Une, Deux, Trois

Suddenly, the sound of approaching footsteps echoes through the corridor outside the room. The air feels charged with tension as the footsteps draw closer. Ciel's pulse quickens, knowing exactly who is coming to their aid. In a flash, the door bursts open to reveal Sebastian, his presence radiating an aura of pure power and grace. His reddish-brown eyes gleaming with a predatory intensity.

"Sebastian," Ciel's voice carries a mixture of rage and quiet confidence. "Dispose of this vermin swiftly."

Sebastian's lips curve into a wicked smile as he steps forward, his demeanor transforming from mild-mannered butler to cold-blooded demon.

"I'm afraid, sir, that your little game ends here," Sebastian's voice drips with barely-contained sadistic glee. And like clockwork, before Fidel could even think, Sebastian stops him from piercing a bullet into _____'s skull. Simply by taking the bullet before it is shot, a terrified expression gracing Fidel's face as he realizes that he hasn't killed the servant yet

"Apologies, are you looking for this? Here. Let me give it back to you"

Sebastian drops the bullet into the mafia boss's breast pocket, Sir Fidel's arm twisting and breaking, allowing ______ freedom from his grasp in a gruesome display of a broken limb. The butler tearing the ropes and such apart in a single pull and freeing Ciel and ______. Placing his Master on the nearby arm chair, while the servant stands up and stretches whilst asking the butler to not hold back

"I'd say no violence. But he's a piece of shit. So don't hold back."

Sir Fidel tries to offer Sebastian more than what Ciel "pays" him, but the butler is uninterested. Saying he does not care for such materialistic desires, exclaiming that as long as his master holds the contract that he is his loyal servant. The air about him darkening, a slight glimpse of his demonic powers shown through the shadows. Causing Ciel to order _____ to come close to him and close their eyes, not wanting them to see or hear any more unsightly things than they already have. To which, they shake their head

"I'm fine with watching... Actually, Sebastian, can I have a kick? Just one?"

Sebastian's lips curl into a devilish smile as he looks over at _____, amusement dancing in his eyes.

"Of course, my dear. Consider it a small gift for enduring such a troublesome encounter," Sebastian replies, his voice dripping with amusement.

As Ciel watches on, ____ steps forward with an unreadable glint in their eyes. Their (size) frame belies the strength within them, fueled by their desire for justice. ______ grabs the beaten man by the hair like he had done to them, lifting his head a good height before harshly kicking him in the face- the man's body crashing into the nearby wall, causing a sharp bang to echo through the room.

Ciel can't help but let out a small chuckle, his eyes softening slightly at _______'s display of strength and resilience. He was certainly a force to be reckoned with.

"Well done, ______," Ciel praises, his voice filled with genuine appreciation. And as soon as he is finished, Sebastian is back at it again. In a flash of movement, Sebastian unleashes his power, tormenting Sir Fidel in the most sadistic and unforgiving manner. The room resonates with the sounds of pain and terror, the air heavy with the echoes of remorseless punishment. Ciel and _______, though both captivated and horrified by the scene unfolding before them, can't help but feel a sense of satisfaction. They exchange glances, an unspoken agreement passing between them. They have endured enough suffering, and now they are witnessing justice being served.

Time seems to blur as Sebastian unleashes his wrath, each strike precise and calculated. It is a potent reminder of his true nature, of the demon that lurks beneath the veneer of perfection. Finally, as Sir Fidel lies broken and gasping for breath, Sebastian stands tall, his expression satisfied. The room falls silent, save for the harsh breaths of their defeated captor.
