A person can change their appearance, their height, and weight. After all, the Art of change is everywhere, they can even change their own aura.
But some people, even after changing everything, can't change the natural scent that emanates from their bodies.
Take for example a woman disguised as a man, even if she changes everything, her body is still hers, and if it originally had a woman's scent, that scent will linger. That's why Dominic Ruiz jokingly asked why the waiter had a woman's scent, and the waiter drew his knife and aimed it at Dominic Ruiz's forehead.
This was also a close-range assassination, and the opponent was very fast, so when Dominic Ruiz reacted, although he used a stone table for cover, what could mere stone achieve?
"Pfft," Dominic Ruiz's half head was pierced, with the tip of the knife emerging from the back of his skull.
