Kanae was a young and beautiful samurai warrior with large chest like Oharu. Kanae has a long blue hair that is tied up and has a samurai female outfit.
Like her family, Kanae is shown to be hot-blooded and passion about fighting and getting stronger.
Sixteen years ago, before the start of the series, Kanae was in Edo where she first met Genjuurou who she knew from rumor and challenged him to a duel, which was what Genjuurou wanted to do. As they dueled, they were both deeply impressed by each other's skills and became eager to continue fighting. Their duel spanded an entire year, and it was during that time that they ended up falling in love. Near the end of the duel Kanae talked about babies' names, declaring that she would bear Genjuurou's child. Jinbei was born soon after that. Later in the show it is revealed that Kanae was once a Insect Hunter and thusly passed the ability to absorb the powers of the eternal Insect down to her son, Jinbei.
Not much is fully known about Kanae ability but due to lasting a fight for a year long against Genjuurou, it seem she is very powerful and a skilled swordswoman. Kanae is skilled enough to copy Genjuurou's techniques after seeing them only once.
