In the old days, political alliances were often forged with marriage. After Oda Nobunaga's sister, Oichi, married Azai Nagamasa they had three daughters who would go on to live turbulent lives.
Ichi, I'm sorry, but you'll have to get 
married for the sake of the Oda clan.
Lo siento, Ichi, pero tendrás que casarte por el bien del clan Oda.
Ichi, sinto muito, mas por favor,
case-se pelo bem da nossa família.
