Jack

Jack(ジャック Jakku) is a spirit of a murder and Matilda Matisse's guardian ghost.

About
Jack was once a killer that lived in London in the early 20th century. His modus operandi was so atrocious that Scotland Yard decided to keep his case a secret. Jack had a gentle personality but one could see the madness in his eyes and he became known as the "Second Jack". He had already killed 112 people, including his own family, when he himself was shot down when he tried to attack a policeman.

But his spirit lingered within his knifes. He was eventually sealed by the witch taking care of Matilda Matisse, but once she died the seal was removed and thought Matilda knew he was dangerous, she still took him as her guardian ghost.
