It's something you've always wondered, right? Well now you can have your answer with the highly-unscientific, potentially reliable Are You Part Demon Slayer? quiz.
Post your score below and I'll enter you to win a copy of The Dangerous Book for Demon Slayers. It's not even in stores until April 28, so you could get a copy before anyone else. The neener-neener-neener possibilities are endless.
And for added contest fun, post your score on my Angie Fox blog and enter to win a walk-on role in the third book in the Accidental Demon Slayer series, A Tale of Two Demon Slayers (coming in 2010).
