I was curious, so I broke down essentially how much each KSS has paid to be in the KSS system... Idk if they get any money from their photos that are sold, but I've never heard of it so I'm guessing not. Each KSS member pays about $100 per month.
Ichioka Reina- $5,100 over 4 years.
Inoue Hikaru- $4,500 for around 3.75 years.
Danbara Ruru- $4,100 for little over 2 years.
Horie Kizuki- $2,700 for a little over 2 years.
Takase Kurumi- $2,300 for a little under 2 years.
Maeda Kokoro and Kanatsu Mizuki- $2,100 for a little under 2 years.
Noguchi Kurumi, Ono Kotomi, Kodama Sakiko, Yonemura Kirara and Kiyono Momohime- $1,300 for a little over a year.
Kawamura Ayano, Yamazaki Yuhane, Nishida Shiori and Hashisako Rin- $600 for a little over half a year.
The senior girls have certainly paid a hefty price in the end...
