Kenma's sister...

Backstory

I am Kiyoka Kozume the younger half sister of Kenma Kozume. Me and Kenma share the same mom but have different fathers. I was conceived when Kenma's father was away on business and was born on October 30th. Kenma's father agreed to give our mother another chance as long as i lived with my father. So my father packed up and moved us far away to America where he blew through many women and often forgot about me. I learned how to take care of and rely on myself for most things. When I was 14 my father died while he was drunk driving behind the wheel. I was sent back to Japan to live with my mother where I met Kenma. Me and Kenmas mom and his dad both traveled for long periods of time so we bonded and became close through our time alone together.
       On my first day as a first year at Nekoma High, Kenma's second, I tried out for the volleyball team and made it. After time my talents for being an amazing hitter we're recognized. I quickly became the second best hitter in all of Japan. I also became assistant manager for the Boys Nekoma volleyball team, this was how i formally met Kuro Tetsuro.
