A Knight Raised by Vampires

A calculated battle, with only one person left in the huge vampire family. Even the most cold-blooded creature will be ignited by anger. When all the silver hair turns to blood, it's time to start the reckoning again. If one person isn't enough, how about adding a baby? If you can't even take care of yourself, you have to take care of others. It means nothing if the child is not there to play with it. The knight's only creed: Even if I am a vampire, even if I die, you must protect me.
