I am Matsubara Kaoru, a middle school girl living in Tokyo with my best friends, Momoko and Miyako. I am tomboyish to the point that I hate everything girly and cute, including the skirt I have to wear when I transform into Powered Buttercup, my alter ego form. I am athletic. I play tennis, skateboard, practice martial arts, and watch sports on TV. I love being a superheroine because it means I get to fight bad guys. My weapon is a hammer. I rarely use honorifics.
