Aya Arisugawa
有栖川 綾
She is Kaname's older sister. She is a lazy ditz, but Kaname considers her on the "genius side" for her great learning capacity. In contrast to that, she usually misunderstands important things and gets really confused in the blink of an eye. Her favorite hobby is playing video games and she usually nags Kaname into playing with her.
