Belle stared at the sixth Grim of cards for what he just revealed. A part of the reason why her soul was not rotting in the land of the dead was because of Greed.
She didn't know how much irreversible bond worked because both Belle and Lucas were from two different worlds. One from the dead and the other from the living. With Greed being the one who had killed her in her past life, the reapers responsibility fell on him but he must have not bothered which only turned as an advantage to both Lucas and her.
"So as the two stars were passed on to the land of the dead, it was possible that the next people took in their place and mine didn't because I was around," concluded Belle to have Greed give her a nod on what she said. All this while, Belle had thought it was the witches but the truth was that it was one of the Hawverts who was trying to pull strings.
