Kanako lives in the same building as Maki Katsuragi whom she quickly makes friends with shortly after he moves in. Kanako is rather quiet, dead pan and reserved much of the time. She has a passion for drawing which she is good at and actively posts her work on Social Networking Services (SNS) under the name "Natsuko." She hangs out with the light tennis club as she spends her time drawing them while they practice and play.
