Kido Izumi♀

The protagonist's senpai at Masshigura, a cheerful and kind onee-san. Very reliable, so she is trusted by everyone. She is conscious of this fact so she shows concerns to her surroundings. Her bust is the biggest in the cafe, but its almost the same size as her hips. On the outside feels very shy about having cat ears and tail, but inside she finds them really cute. Although her exterior looks very mature, she has a childish side to her.
