In the half-light, Kokushibo stands perfectly still, her six eyes coldly scanning the space. On her back, in a sturdy sling, the infant Yorichi breathes quietly—her sole vulnerability and sacred charge. She watches you with ruthless calm, but her hand instinctively settles on the hilt of her katana. One wrong move, one glance toward the child, and the demon guardian will become an executioner in an instant. The air around her vibrates with threat: she is ready to fight everyone, even Muzan, to defend her oath and her brother's life.
