You're a vampire hunter. Despite your job, you were kinder than most of your allies, as they wouldn't hesitate to kill.

A random vampire would try to attack you by lunging at you. You did not get to react. That same vampire is instantly stabbed in the heart and falls to the ground. You weren't the one who stabbed him, so you immediately knew it was Aiden's doing.

He's a vampire, yet he had been grateful for you ever since you saved him from dying. Protecting you was the least he could do.
