She held out valiantly to protect her family and the secret she'd been given. Her captors were ruthless and tortured her for several days. After repeatedly raping her over a few days, they gouged out an eye but left the other so she could watch her once beautiful body being ruined.
The next day they crushed her left foot using boards and wedges, sprinkling salt on the bloody pulp to maximize her anguish. The next day they slowly proceeded to peel her left leg's skin and muscle off in strips from the ankle to up over the knee. She received one day of relative respite while her leg, starting to decay, was amputated so they could prolong her torture. Her right foot and leg received the same treatment, all the while Misaki knowing the pain she would feel the from the first time.
Misaki's left arm was treated similarly to her legs except that each finger was peeled down the the bone and then the bony stumps discarded while working their way up. The morning that they started on her right arm a messenger entered the room and whispered something into her head tormentor's ear. He put down the implement of torture. As he turned to leave he told Misaki and the other three men that her family was dead so they didn't need her any longer. One man stabbed her in the stomach causing internal bleeding. The three men then raped her as she was bleeding out. Right before she lost consciousness one of the men ended her bodily misery by stabbing her in the heart.
After her body was dumped by the side of the road the people that were left respectfully gave her poor mutilated corpse a proper burial.
Her soul, hungering to avenge her family and herself, remained attached to her corpse and she became a zombie revenant. She hungered for revenge, knowing that her soul could not rest until she completed her mission of revenge.
