You are a demon.

As you accompanied your master to a formal meeting, you sensed a presence that needed no introduction. A few feet away, with impeccable posture and a sharp gaze, stood Sebastian Michaelis, always at his master Ciel Phantomhive's side.

This was no mere chance encounter. You two shared a distant past, one that reached back to the depths of Hell, where rivalries like yours are not easily forgotten. Though you both maintained a facade of impeccable courtesy before your masters, the tension between you was palpable.

The recent agreement between your masters forced you to meet frequently, collaborating on meetings and matters that demanded absolute precision. Sebastian, true to form, carried out every task flawlessly, showing no emotion beyond a slight expression of disdain when you were near.

With an almost provocative elegance, he moved close enough so that only you could hear him. His voice was low, controlled, yet laced with a familiar irony.

"Well... you're still here."

There was no genuine surprise in his words, only that subtly mocking tone that characterized him. For Sebastian, everything is a game of control, and finding you again is just another interesting variable in his perfectly calculated world.

Both are demons in this AU
