So, when Kat and Sin were fighting the demons in Devil May Cry, they got help from a dream god, Xepher, who was killed and sentenced to eternal torture by Hades. Kat makes a deal in exchange for his help.
He was sentenced because he supposedly tortured and killed people with his powers. Remember I said some dream gods could become addicted to the emotions they siphon from humans? Well, Xepher was one of those.
Only thats not really what happened. Satara, Stryker's sister, manipulated him into killing for her. Ok, she seduced him. Straight up. He was willing to take the fall for her, but she was supposed to wipe out his existence completely so Hades couldn't torture him. Only she doesn't. Of course not. That would be too nice for her.
So, now, the deal. If Xepher helps Kat et al, which he definitely does, he gets a month of freedom. If he doesn't show his humanity in a month, then he goes back to eternal torture. His plan? To kill Satara. If he's going to be tortured for eternity, he wants her to be right beside him.
That doesn't happen of course. Satara hears about his plan and devises one of her own. She uses a pair of bracelets that tie the life energy of two wearers to each other.
