Asuna Hibiki works as a maid/bodyguard for the Sugiyama family. She is the maid for Yuuta Sugiyama the next head of the family. Besides being a maid she is also a part of the Sugiyama private security force (Dark Foxs) Their job when not acting as maids or butlers is to keep those who want to harm the family and those who have seen or heard too much. In one of Asuna's last missions, she was tasked with making a person who heard something that the head of the family didn't want leaking out. So she caused his car to get into an accident. When it was all over the police ruled it as his fault. Causing the man's family to go into debt. Since then she has been keeping an eye on the family since Master Yuuta is "friends" with the son of the family. In case they do know something about why Mr. Yukimura died.
