Backstory: Kane was once a brilliant, idealistic scientist working to solve humanity’s problems. During his research, he discovered the portal to the other world and became obsessed with it. As part of the project, he met and fell in love with a woman who worked alongside him—a human with a passion for protecting life. However, she saw the greed and corruption in Earth and turned away from Kane’s ambition. She eventually fell in love with a man from the other world, a being who represented everything Kane despised. Kane’s heartbreak turned to rage when she chose to live in the other world, seeing it as pure and worth protecting, while Kane viewed it as an untapped resource for humanity’s survival. To him, her betrayal was personal—choosing "the enemy" over him. Aria, their daughter, is the living embodiment of that betrayal, a constant reminder of the family he believes was stolen from him.
