As the patriarch of the Qiushi clan, she witnessed the destruction of her family with her own eyes.
She is also the last one to survive, the only 'Autumn Shi'.
She originally believed that this family that could compete with Uchiha and Senju would definitely be able to accompany her to the end. As the strongest ninja in the 'Autumn Period', she would definitely be able to protect the family.
She is still too naive.
In this troubled world, no matter how strong you are, you can't escape the so-called 'fate'.
