Kanako Sanjo is a girl that joined the Annex I Project under Komachi Shokichi's tutelage. Her mother and father were a tv personality and a famous soccer player, respectively. Like her parents Kanako too had a promising future as a track-and-field star but her life had a turn for the worse once her father was discovered using performance enhancers. Her mother's involvement in some shady business started to form a rift between the two leading to Kanako's departure from home. Due to the ever-increasing loans her family racked up, and the dogged pursuit of the authorities, Kanako began looking for money to sever her connections. For this reason she joined the Annex Project.
