Caterina Sforza  

Caterina Sforza is a determined woman who leads AX, a subsection of the Department of Foreign Affairs. She frequently resolves cases that involve suppressing or eliminating rogue vampires. While advocating for peace with the Empire and humans living together harmoniously, she often clashes with her brother Francesco over this concept. Caterina has known Abel for many years, as he saved her from a vampire attack when she was young.
