New to the sport, Shiba does not have a good grasp of the happenings in the tennis world. For this reason, although she conducts occasional interviews, her role is more of a photographer. She is slightly immature for her age, and is a bit shallow when it comes to the appearance of the players she plans to interview; however, this was only towards the beginning of the series. She is seen to no longer have this bias by the end of the series. She is normally seen with Inoue Mamoru going to different middle schools and tennis tournaments for their company, Monthly Pro Tennis.
