Chinatsu is a rollercoaster of emotions and a strong-headed person who wants to do things her own way. It's said she has a perfect dancers body.
Chinatsu is the same age as Tatara and they meet at high school in the later half of the anime. She loves to dance but has a bit of a hard time adapting to Tatara's pace. She began dancing at the age of 7 and partnered up with girls as the lead because male partners were harder to find (fewer men interested in dancing).
