The Woman with Golden Fingertips
Headcanons for Uro for my kickass friend (tis is me just making up characterization lmao)
Uro's life during the Heian Era was frustratingly unremarkable; born into a world in which sorcery served as a currency for power, she was just strong enough to achieve something, but never enough to be anymore than a side note on someone's peripheral.
Namelessly walking across the earth as servants for another family, Uro couldn't reach for anything she really wanted.
I think that she was born alone, and was sold to the Fujiwara's military troops at quite a young age, due to her promising technique.
Much like Sukuna, she shares a hunger for status, but she never had much more ambition aside from a leading a life of what she considered comfort. This helped her rise in rank until she was at the top, but Uro could never conceive of anything beyond this, so she never surpassed this level and remained stagnant.
This also meant that while her technique had potential, she stopped progressing at some point, unable to reach the heights of someone like Satoru Gojo or Sukuna due to her mental blockage.
That blockage resulted from the Fujiwara grooming her into a leader of their military faction. They systematically cut down any development into anything bigger that Uro could have been, since that would eventually mean her alienation from their ranks.
During this era of Jujutsu, we are still discussing the Strongest as a concept of individualism and selfishness in pursuit of your goals, not a symbol of unity as the finale suggests (in my opinion), so when Uro reaches her climax at the top of the military power structure, she stops progressing. This is for a few reasons.
One; her progress until this point had been pushed by the Fujiwara, who her entire identity formed around. When she reached this military station, she didn't have a need to change anymore, since that was where she was supposed to be.
Secondly, when this goal was completed, she simply had to work to maintain it, anything around that didn't exist anymore, and so she couldn't keep up with the rest of the sorcery world. Not pushing further is basically one of the biggest faults you can have in JJK, since that conflicts with the idea of exceeding your own limits.
Lastly, I think she gets comfortable, because like said, she didn't really know a life outside the Fujiwara, and had no metric of freedom.
Subsequently, these three factors lead to her eventual defeat. Uro couldn't keep up with the rest, and fell off. The Fujiwara noticed and threw her away when they had the chance.
They gave her a name and executed her. Strangely, this little action of giving her a name promptly accelerates Uro's identity. Not because she has a name now, but because it signifies the betrayal at the hands of the Fujiwara.
It's like being gutted; Uro spent her entire life serving them without question. She is so confused, when they come to lock her up for the ceremony, she doesn't resist and just walks along.
Her hatred and rage are so tight in her chest, it feels like her cursed technique is crushing her, and so she makes a decision without the prompting of her masters for the first time. It's a decision of defiance. She strikes a deal with Kenjaku just before her execution to come back during the culling games.
If they betray her, if they use her and sentence her to death, than she shall outlive them.
Meeting Yuta then was a massive middle finger, because in the end, she never even got to outlive her abusers, and their wretched blood keeps running in the modern world.
Same with Sukuna; the man that lead her to her downfall through defeat is uncontested in the modern era, and she is paralyzed by fear, and can't face him.
That beautifully sums up the tragedy of her character. Too late did she realize she was just being used, and when she did, she still couldn't break the programming of her conditioning.
Uro deserved better, but she can't get better; not in the Heian era, and not in the Modern era.
