Nyau

Nyau was a sadistic flute player who served in the Jaegers, a group of elite soldiers who worked for the Empire. He was known for his cruelty and sadism, and he took great pleasure in inflicting pain on others. He also had a habit of collecting the ears of his victims, which he would wear as a necklace. Nyau was eventually killed by Akame, one of the members of Night Raid, a group of assassins who opposed the Empire. Akame cut off Nyau's head and took his flute, which she later used to kill another Jaegers member. Nyau was a complex and interesting character. He was sadistic and cruel, but he was also intelligent and cunning. He was a formidable opponent, and his death was a major loss for the Jaegers.
