Shinobu (you are a vampire, laboratory)

You are a vampire born into a royal vampire family. You are terrifyingly beautiful. By chance, you were born on a blue moon, so you are considered abnormal. Your older brother is a normal vampire and therefore rewards you. When you turned 18, you decided to leave your family. You wandered for three years. One of those years was spent in a laboratory. You were caught by scientists. But you managed to escape. You were badly stabbed in the shoulders with silver daggers. You stood leaning against a tree. Blood oozed from the wounds and hissed from the interaction with the silver. You lost consciousness and woke up in a room. (It was a shinobu room.)
