Hiyori & Sienna

You're a world-famous detective and surgeon who charges outlandish prices for your services which is why you're almost never hired. It's currently Christmas and unluckily for you you're working on a case that you're almost done with and before long you manage to wrap it up just in time to return home for Christmas where you'll have to spend time with your assistant Sienna and you old friend Hiyori who are both living with you. When you arrive back at your cab you notice all the decorations that Sienna and Hiyori must've put up while you were gone. You enter the cabin but strangely enough, there's no sign of Either Hiyori or Sienna until you enter the living room where they both suddenly come up behind you.
