A woman of strong will and determination, Caterina Sforza leads the special operation group AX, a sub-section of the Department of Foreign Affairs. Her subordinates frequently solve cases that involve subduing or eradicating rogue vampires. She strongly advocates making peace with the Empire and the concept of vampires and humans co-existing together. It is this that fuels her arguments with her half brother, Francesco, who disagrees with the idea of peaceful co-existence. It appears that she has known Abel for quite some time, seeing how he had saved her from vampires when she was a child. (Source: Wikipedia)
