|Chitose's Older Sister|
|Anime Appearance||Episode 12 (flashback)|
|Manga Appearance||Volume 4 Chapter 35|
She is Chitose Karasuyama's older sister who is 10 years older than her. Contrary to her sister, she has a very weak physical condition. She felt a little lonely after Chitose started to become energetic.
She cares/worries a lot for her sister as seen in the past when she was trying quite hard for her sister to make at least one friend because she was always playing by herself.
She also seems to be easily impressed as seen when Roka Shibasaki was acting all cool when she first met he little sister when they were both 4 years old.
- In a bonus manga omake, it is shown that Kenji Kazama met Chitose's Older Sister in his childhood. Chitose's Older Sister unknowingly scared him off, causing him to run away with his sister and Takao.
- Years later, Kenji met her again (chapter 37) but did not recognize her or make a connection to Chitose.
- She appears to get sick often.
