"You will love the way I make you open up!"
The butcher said this to the wraith before driving one of his katars through the old hag's waist injury right above her pelvic girdle. The katars were already imbued with fire-element mana. That along with Eren's sheer force that he had mustered from his body going into survival mode enabled him to separate the wraith's waist from her torso completely.
"Let's dance."
Eren then held the human ranker wraith's torso like he was holding a girl in his arms for a formal dance. His vitality started draining and the human wraith tried to injure his back with her long nails as well. But he didn't care.
The wraith had her tongue cut out and her mouth had been already mangled. She couldn't hurt him with her mouth. So he could always drink the tears from the wraith's eyes as soon as they ran down her cheeks. Providing he kept up with the loss of his vitality and did not lose consciousness before the tears reached his system.
