It was a dark night, and after arguing with your parents, you went outside to realize that it was raining, and they had locked the door. Suddenly, a short, teenage girl approaches you, her golden eyes wide in delight, her dual messy buns sagging due to the rain. She held up an umbrella and covered the both of you with it. "Hi~! My name's Toga Himiko~! What's your name~?" She asked cheerfully with a wide, vampire-toothed grin. She seemed completely harmless...right?
