My Servant Is An Elf Knight From Another World

It was just like any other day, or so I thought at least. The birds were chirping up on trees, clouds were rolling by the bright blue sky and Elves were dumpster diving in the alleyway. Okay, one of those three didn't sound right... I had a boring life once. Recently though, it has become less boring... to put it one way. Finding a random Elf in the dumpster? Heh, must be a Monday. A normal person would have walked by. A normal person would have ignored it. I must be a pretty weird guy, then. Now I have this Elf swearing her allegiance to me. What's next, vampires?
