Nadeshiko is described as being more lenient and caring towards her daughter than her husband is. Karin learned most of what she knows from her mom, who apparently is able to bewitch 500 men at once with a single glance.
Nadeshiko has not made any official appearances yet. What is known of her so far is that in the past, as part of her pre-wedding qualification test, she had to charm 50,046 gentlemen, including Daigenjuro. Her husband also loves Nadeshiko a lot despite her having birthed a girl instead of a boy (as he wanted a male heir to the Kanzuki family fortune). She also runs the household while her husband's at work in the Zaibatsu.
