Tucked away in the remote corners of Japan stands the estate of Dr. Naomitsu Madaraki, a surgeon infamous for his horrific procedures. In his absence, his artificial daughter Fran assumes control of the mansion and his gruesome surgical practice. Assisted by her violent younger sister Veronica, the human-cat hybrid Okita, and Dr. Madaraki’s other macabre creations, Fran attends to the peculiar requests of her clients. Whether removing tumors or reviving the dead, no two jobs are the same, yet no task is too difficult—or too dangerous—for Dr. Madaraki’s successor. This eccentric medical prodigy will do anything to save a life, even if her results are rarely pretty.
