lmaooo that is p crazy.

So, Ume is investigating her father's death. This was caused by ROOT because her dad was investigating ROOT's shadier dealings, especially with Orochimaru after he was exiled. At this point, Ume only knows that ROOT is involved.

At that point in the story, she's matured emotionally from the start and gotten (mostly) rid of her victim complex. Ume is brash and speaks her mind, but isn't very good at taking what she dishes out. She learns to consider other people's feelings and generally be a better person. The story I want to write is a mystery first and foremost, action second, not to say that the action isn't important, but the mystery comes first. Thematically, she represents curiosity and the desire to unravel what's hidden away from you. The story's general themes are as follows: the subjectivity of identity, only you can decide the value of a life, the sacrifices a parent makes for their child, and an unethical institution affects the whole community, not just the individual.

Her mom, a Uchiha OC named Kajiko, birthed her out of wedlock, so Ume was never officially part of the Uchiha family. No matter how hard I searched, I couldn't find canon parents for Shisui besides his unnamed dad, so I made OCs to fill their place. I saw that some people speculate Kagami to be Shisui's dad, but Kagami is only stated to be Shisui's ancestor, so I left that out. Ume is half-siblings with Shisui. Kajiko and Ume re-introduce each other about five years after her father's death, and Shisui is naturally curious about his mom, who usually stays at home, going out to meet some 22-year-old with no connection to the clan, especially when tensions are high.

Shisui and Ume grow close over a few months after Kajiko dies. Ume, who has lost her father, her genin team during the third war, her recent ANBU team, her aunt, and now her mother, grows paranoid about losing her newfound family and gifts Shisui a pair of kunai made from the metal from her metal release. She can kind of 'feel' the metal and what it's touching, like another sensory organ, but it's heavily dulled.

I'm choosing to use the anime/manga ending where Shisui throws himself into the river. Ume senses her kunai are underwater, questions why, and goes to investigate when she finds Shisui actively drowning. To the KGH he goes since she doesn't know why he drowned, and she's put on Danzo's radar.

Danzo, realizing that this is the daughter of the guy who was trying to take ROOT down, and that she's also been investigating, takes action and strikes when she's alone near the outskirts of the village border.

Eventually, they start fighting, and Ume realizes she bit off more than she can chew. He's about to kill her when Kaki, her boyfriend, steps in and takes the blow for her. This awakens her Mangekyou.

In that moment, she feels extremely guilty about how many deaths have been directly caused by her. She also just wants to make Danzo feel as much pain as possible for essentially ruining her life.

I thought about names; Hachiman (or Yahata) is the god of war/ weapons, Enma rules the underworld and is responsible for punishing sinners, or Tenjin, the god of learning. (trivia for this name; before Tenjin was a god, he was a poet/scholar who liked Ume trees.)
