Nyau (ニャウ Nyau) was a member of Esdeath's elite bodyguards, "The Three Beasts". Nyau was a young man of small build with blond hair and golden eyes. He wore the same uniform as the other Beasts, with the exception of wearing shorts instead of pants. He also had horn-like accessories in his hair and a demon-like tail; his teeth were shown to be sharp. When activating his Teigu's Trump Card, he gained a large, muscular body. Like his comrades, Nyau was extremely loyal to Esdeath and was willing to follow her orders, even if it would cost him his life.
