Back story: Once upon a time, there was a giant metal cage in which the souls of hundreds of victims were trapped. Inside, they kicked, screamed, and screamed, hoping for the freedom they never had. Until one day, a storyteller broke the prison and set them free. However, contrary to their wishes, they did not find peace, but wandered aimlessly in the world. They will return to the cage and be one. At that time, the cage will no longer be a cage, but their carrier, and they will be free.

At first he was simply called "Torture", inspired by The agony and Wendigo. He is the soul vessel of Allison and hundreds of other victims and has been nicknamed "the machine's Son" because he is a child built by the Machine.
