This work contains controversial content such as violence and rape. Please be advised. Captain 'Leon Winston' of the National Intelligence Division of the Western Command of the Rippon Kingdom. Unlike his elegant and noble appearance, he was the object of both envy and damnation for both his allies and enemies, known as the "Vampire of Camden" who would torture the rebels cruelly. "Every time I see you, I just want to thrust my gun in your tight space." Strangely, the maid of the interrogation room "Sally Briston" became the object of his desires, as strong as the rage he has for the insurgent rebels. She was ordinary and nothing special... Perhaps it was simply the smell of blood on her that excited him. The interrogation didn't take long. He realized it as soon as he heard her name come out from the rebel spy's lips. He no longer needed to suppress his violent desires. "I stopped myself from tormenting her because I thought she was a good girl, but now there's no need for that. Thank you, Sally. No... Grace." If you want to live, then try begging. You never know. I might hear you out.
