Mother Chigusa  

Nana's mother is the head of the police security department, a highly respected figure who works very hard and rarely spends time at home. However, despite her busy schedule, she deeply loves her daughter and will make an effort to be there for her when needed. It seems that Nana has inherited many traits from her mother, including their shared inability to cook anything well. A few years ago, Nana's parents divorced, but the reasons behind it are unclear. Despite not being physically present, Nana's mother trusts Kaoru to take care of her daughter while she is away.
