She is the manager of the Nishiura baseball team. Very hardworking and earnest, she has great pride in the baseball team, and does her best to help out the team in anyway possible, from making rice balls to writing detailed reports about opposing teams. As manager, she has lots of information about her own team, and knows all of their full names and birthdays. She went to the same middle school as Abe and Sakaeguchi, where she played softball in the position of shortstop. Chiyo also loves trying on other school's uniforms, and often swaps uniforms with her friends and takes pictures.
~!She stated (in chapter 17) that she has no romantic interest in anyone on the team, but it is later revealed (in chapter 59) that she has feelings for Abe, though she won't act upon them to avoid awkwardness in the team. !~
