The Secret Life of Lavinia

Hi. My name's Lavinia, but my friends and bros call me Nia. I'm your regular, badass kunoichi from NYC. I've lived in the sewers for the passed 8 years, training with my bros. I've had to fight mutants, ninja armies, and the Shredder himself. There isn't anything too challenging for me. Well... maybe one thing. I think I might have a crush on my hotheaded best friend. Any advice?
