Mayu Kanzaki

Height: 142 cm

She is the ex-girlfriend of Ootani. She looks very similar to Chiharu (or Chiharu to her), which is one the most likely reasons that Ootani had that crush on Chiharu. They started dating in middle-school, and she was the manager for the school basketball team. She broke up with him, leaving him completely heartbroken, because she was in love with someone else that just so happened to be really tall.
