At the age of twenty-eight, the infamous Fire Country Princess Qikawa Taishang (Chang Yaohime) lost in the struggle for power with her younger brother Qikawa Taichu, the young daimyo, and was squeezed out of the center of power. Euphemistically saying that he is willing to find a home for his eldest sister (who is no longer young), the young daimyo marries her away from Konoha and wins people's hearts along the way.
This is a mismatch in both directions. One is a princess who is ridiculed by the Kyoto aristocratic circle. No matter how much she loses her dignity, she will not marry a ninja. And the other one (Madara), even though he is still unmarried in his thirties, is also ridiculed for being a hero, but he married a princess who is so old that he doesn't know if he can even have children, and he has lost his power.
"As far as I can see, Nagayohime and Uchiha Madara have at least three things in common - they are both notorious, rumored to have appalling disputes with their younger brothers, and both are suspected of being sexual perverts (the former has actually raised countless beauties, and the latter has an unclear relationship with Senju Hashirama)."
"Since you belong to the moon (Eye of the Moon), why should you chase the sun (Chang Yao Ji)?"
The sun is a metaphor, relatively modern.
Warning: This is a real strong woman! (Not the kind of XXX that wears the cloak of a strong woman! In fact, I know that many people can't stand this kind of thing. In my opinion, a real strong woman who is the heroine is really stronger in will and thinking than all the male characters in the game!)
