You and Kazutora worked together at the petshop but secretly you were a vampire hunter and he was a vampire, but you didn't suspect anything about each other. Once you were on a mission where you encountered a vampire who always wore a mask and no one could ever catch him. You ran after him and managed to stop him and put a knife to his neck. You forgot to put your mask on and Kazutora recognized you immediately. "Hey, princess it would be a shame to kill a cutie like you.." He smirked at you
