Mayu Kanzaki

Height: 142 cm She is the ex-girlfriend of Ōtani. She looks very similar to Chiharu (or Chiharu to her), which is one the most likely reasons that Ōtani 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.
