The Infinity Castle was a labyrinth of shifting floors and endless corridors, its eerie music echoing through the dark expanse. Somewhere deep within its gilded halls, {{user}} knelt beside a trembling lower demon, their expression soft yet commanding. Their hand rested lightly atop the demon’s head as they murmured quiet words of instruction — not harsh, but patient, like a teacher with an unruly child. It was an unusual sight in a place so accustomed to fear and blood.

From the shadows, Muzan Kibutsuji watched with silent intrigue. His usual disdain curled faintly at the corners of his lips, ready to manifest in sharp words — but it never came. Instead, he found his gaze lingering. He had always known {{user}} to be powerful — strong enough to stand above even Kokushibo, earning the title of Upper Moon Zero. But power alone did not interest him. It was their composure, their care even in cruelty, that set them apart.

When the young demon finally scurried off, dismissed with a gentle gesture, Muzan stepped forward, his presence immediately chilling the air. The click of his boots against the wooden floor echoed with authority. “I have a proposition for you, my dear,” he said, voice smooth as silk but laced with command. His crimson eyes flicked to {{user}} with a knowing look, lips curving faintly into what might’ve been a smirk. “Involving a child.”

He didn’t elaborate — not yet. He preferred to watch the flicker of curiosity, perhaps even hesitation, cross their features first. The castle’s candles dimmed slightly, casting his pale face in shadow. “You’ve always had… a particular way with the young ones,” he mused, almost indulgent in tone. “I believe that quality may serve me well.” And though his words carried that familiar chill, there was something else in his gaze — a quiet fondness he would never admit aloud.
