Kaoruko's Fervent Study
Description
Chaldea is full of female servants lately, and they all really want to serve their master. Conflict became so bad that a duty system had to be created to avoid conflict, so that they can all enjoy serving their commander. Kaoruko’s views on the world are from a very different time, and in performing night duty for her master, she finds that sexual etiquette has changed considerably since her day.
