It was hard to be a woman during the Sengoku period. You'd have to be a real tiger to survive among the constant warfare between rival daimyo... And that is exactly what Ii Naotora did!
At the time, women were not 
allowed to be feudal lords.
En esos tiempos, las mujeres
no podían ser señoras feudales.
Naquela época, mulheres não
poderiam ser senhoras feudais.
