Gozuki

Gozuki served as the head instructor for an elite assassination unit, personally training its young members. For eight long years, he cultivated a fatherly image, leading children like Akame to revere him.

Through his special training, he meticulously molded these children into the Empire's most efficient assassins.

On the surface, Gozuki claimed to cherish his students like his own children, but this masked a much darker nature. He possessed a fearsome demeanor and was mercilessly cold, willing to dispose of any subordinate who failed a mission.

Despite his cruelty, he had developed a genuine, albeit conflicted, attachment to his "family." He tried to dismiss the death of Cornelia by calling her a "useless kid," but he couldn't deny the sadness he felt from their time together.

He was particularly bothered by Akame, as she was the only one who didn't offer him blind devotion. To test her, he once cruelly ordered her to assassinate someone she deeply trusted.

Gozuki was formerly known as one of the elite Four Rakshasa Demons and is the biological father of Mez. He was entrusted with raising the next generation of Imperial assassins, a task he performed with brutal efficiency.

Sensing that Akame was about to defect from the Empire, he set a trap for her with Tsukushi and the other assassins. He pursued the fleeing Akame and engaged her in combat, but she ultimately defeated and killed him.

In his final moments, Gozuki was met by the souls of the dead children from his unit. He mocked himself, believing he didn't deserve to see them, but came to a peaceful realization that no matter how twisted he was, he was still their father.

Gozuki was an incredibly skilled assassin and the master of many of the Empire's top killers. He was the wielder of the Teigu, One-Cut Killer: Murasame, before it was passed on to Akame.
