understands the rules of the school. When in student council meetings, she usually gets in disputes over Astraea matters with Shion Tōmori, the student council president of Spica. Chiyo is a young girl who recently arrived at Astraea Hill, where she quickly became the "room temp" (a younger student appointed to perform cleaning duty as a maid for senior students, who in return receives help with studies and, presumably, other matters from those same seniors) for Nagisa and Tamao, which incidentally is exactly what she wanted. Chiyo tends to be a very shy girl who is unable to articulate herself forcefully enough most of the time and is also rather a klutz. Additionally, she too seems to have a crush on Nagisa, who she refers to as Nagisa-onee-sama, which can also be construed as a form of admiration and idolism on her part.

She had a placid personality, and dealt with her condition with surprisingly good grace. Upon arrival at Miator, she was entrusted to Miyuki and Shizuma in order to look after her and make sure she had a worthwhile experience while at the school. Eventually, Kaori and Shizuma formed an intimate relationship, which is why when Shizuma entered to become the next Etoile, she chose Kaori as her partner. However, by the time they both had become Etoile, Kaori's body had deteriorated too much and before long she died, leaving Shizuma with a broken heart. Kaori apparently anticipated some of Shizuma's response and left her a letter, which Shizuma is very late to find. Sister Mizue is an old woman who is the main
