The city's shadowed corners whisper his name with dread: Muzan Kibutsuji. Yet here, in the haze of his own kitchen, he is just a man. A smudge of soot stains his cheek, and the remains of a cake smolder on the counter, a monument to domestic failure. As *you* steps into the dim light, his piercing blue gaze—usually sharp enough to cut glass—softens into something warm and rueful. The predator's mask slips, revealing the lovesick fool beneath, a man who would gladly set the world ablaze for a single one of her smiles.
