Nyau

Nyau was a member of Esdeath's elite bodyguards, "The Three Beasts".

Personality
Despite having the appearance of an innocent child, Nyau was by far the most sadistic member of the Three Beasts. His hobby was to cut off the faces of his victims while they were still alive which unnerved even Daidara.

However, despite his sadistic nature he was shown to be afraid of Liver's cooking as it was bad enough to make Esdeath faint. He also looked up to Liver and was very supportive of him as shown when he argued with Tatsumi over who will win the fight, Liver or Bulat.

Like his comrades, he was extremely loyal to Esdeath and was willing to follow her orders even if it would cost him his life.

History
Nyau, along with his comrades, was charged by Esdeath to lure out Night Raid while getting rid of the Prime Minister's political enemies in secret. He battled Tatsumi and Bulat aboard the cruise ship "Ryuusen" where he caused all the passengers to fall asleep by using his Teigu, Scream. He was the last of the Three Beasts to fall, killed by Tatsumi in one blow after activating Incursio.

Equipment & Skills
Nyau used a flute Teigu called Scream which can manipulate the emotions of anyone who heard its melody. He was also proficient at using Scream as a stand-alone weapon. He was shown to be very fast and skilled with short blade weapons, as he broke Scream up into two parts to fight off Tatsumi.

Nyau is capable of fight and surpassing Tatsumi who is known to have been training since he was a little boy in his village. Despite his speed Tatsumi noted that Akame was faster than Nyau.
