Kaori "Kai" Humemuro
18 years of age.
She was 15 when Mama-san Michiko adopted her into the house.
From the fishing village of Hokkaido, her father was a fisherman while her mother died from giving birth. The chaos had lead them to borrow money to let them survive the aftermath of the war. The only way to pay for the debt was to let Mama San Michiko adopt her.
Witty yet reserved. That's how most people would describe Kaori-san. Her small and fragile built had prevented her from doing jobs for her family while Mama-San Michiko saw it as an advantage to become graceful and to become a great Geisha but soon Mama San Michiko is having second thoughts about her decisions of adopting the weakling.
