• In his childhood, he was very weak, as he was a medium like his real father and was very sensitive to otherworld entities.
  He was told to hide himself in family house, 'cause he looked very different from his siblings, but was sent to Duke Zero's house for trainings anyway. His last one ended unwell for him, he was heavily damaged by monster and almost left to die all alone, if not Mael, who was nearby and found him.
  Mael returned to home with him and took care about him, even if he saw Jack really rarely and Jack almost lost all his limbs in this incident and cried asking him to left him alone, 'cause he's useless now. With Teo's help Mael did his best to help him to recover and made his life almost normal - he even asked Taylor to create special long gloves for Jack.
  Since that time Jack almost got used to his new life, and finally was able to unite with his family. He hides it, but his romantical feelings also returned, but he is too shy to search a pair actively.
