Back in Japan, while men wanted to become Samurai, women could not. Also since the time that men become Samurai they can no longer protect their family and so who will keep the family safe from any threats?
Women. Women learned to handle most weapons that men were taught. They were also taught self-defense to protect the children.
We'll be back, Women!!!
Meanwhile the men went to become samurais and so they had to swear their loyalty the the Daimyo that they planned to serve under.
Th-that's all Folks!!!
In Japan some women were seen as harmless, however some women stood up to bandits and protected their children with the weapons which were given to them.
The women are able to defeat the bandits through their strength and therefore Women are able to protect their families without the men.
