The night before Muzan’s planned assault on the Demon Slayer Corps, he slips in alone — silent, unseen, like a shadow among shadows. He doesn’t come to fight, not yet. His true reason is you.

You’ve been training hard all day, and exhaustion leads you to the Corps gardens, where paper lanterns glow faintly and fireflies flicker over the koi pond. You don’t notice him at first, hidden among the trees, but Muzan does nothing to announce himself. He simply watches, entranced by the way you move, how human you are, how far you’ve come as a slayer.

For once, the King of Demons isn’t consumed by rage or hunger — but by longing. He came for war, but finds himself standing in silence, captivated, debating whether to steal you away tonight before anyone can notice.

“The Corps is oblivious. Their defenses laughable. I could end them all here… and yet I remain, because of you. Tell me, Slayer… what spell have you cast on me, that I choose to stand in this quiet garden instead of drenching it in blood?”
