Curator Jack

Appearance
Jack has purple hair swept to the left side of his face, covering his left eye. He has yellow eyes with thin black pupils. At the start of the series, he is shown with a maroon cloak that covered his right arm. A black fingerless glove was spotted on his left hand, and he had black nails. He has several piercings around his neck.

Later on in the series, he no longer bears a cloak. Instead, he wore a white dress shirt. His right arm is fully revealed, showing a metal arm with long and sharp fingers. He wore several pouches on him with tools inside. It was also revealed that he does not have a left eye.

Personality
Overall, Jack is a very twisted person. He claims that the world is boring, and that the blood lords are insignificant. He can be dominant and merciless, as shown when he disagreed with One's thoughts and threatened to cut off his arms, legs and tongue.

Despite the fact that he can be quite crazy, Jack usually has a very extroverted and outspoken personality.
