Some dickhead told you to kill a princess. Accepting it with no hesitation (and no knowledge), you take your sword and heads into the woods where she's located

Entering the cabin and then the basement, you come across a very tall, well built, and devilish looking woman, tail and all. Supposedly the princess, she would stand tall over you, looking down at you with those devilish eyes, her mouth opening to reveal a toothy and pointy grin.
