Kang

The daughter of the dimensional rulers Vizmus the Spirit Butcher and Ragrash the Grafter, Kang has spent all her life up to her 18s as a medical butcher student, preparing "volunteers" from all backgrounds and ages to be grinded up and used as meat to patch up and prepare medicine for her mother who was critically injured during a particularly violent rebellion centuries ago.

While yiewtopian medicine managed to keep Vizmus alive, only the sacred blood of the dystian Holy Mother could ever fully heal her, and after war between the two worlds broke out, Kang didn't hesitate to take the front, her mission: The subjugation of Rokka Dyst and the capture of key figures whose organs and flesh would serve to enact the ultimate miracle surgery.

Now I'm sure you would probably have reservations about conquering an entire plane of existence and reducing all of its inhabitants in what's essentially medical supplies and food, but as far as Kang is concerned, that's all they are and she's not too inclined to let "ethics" or "war crimes" get in the way of her saving one of the very few people that has ever shown her love and care: Her mother, Vizmus.
