Chigusa has brownish orange hair styled in a high bun; it is held together with a pink barrette adorned with three small roses. She has pale skin and light blue-green eyes. She is slightly taller than Gou. Her typical school uniform consists of a light-brown skirt, white shirt with a red bow tie, beige long sleeved jumper, dark gray button-up blazer, dark gray socks and black shoes. During the spring and summer, she would wear her summer uniform, which consists of a gray skirt, white shirt with dark gray collar, red dotted bow tie, beige sleeveless jumper, white socks and pink shoes.
Chigusa seems to be a very curious and inquisitive individual, since she cares a lot about Gou's relationship with Haruka, Makoto and Nagisa. She always forgets to address Gou as "Kou," which results in Gou getting upset and correcting her. In addition, she is considerably athletic; she runs much faster than Gou and she often has to stop and wait for Gou to catch up with her.
Chigusa appears for the first time as she runs towards the school building and Gou runs after her. Later, the two eat their lunch on the roof and talk. The next day, the two watch Haruka, Makoto and Nagisa sitting on the grass; Chigusa, subsequently, finds out that Gou knows the three, but she does not reveal her relationship with them.
Chigusa and Gou attends a summer festival together, where they wear yukatas.
Chigusa is a close friend of Gou, and they occasionally hang out with one another.
