Her first mistake was seeing people who weren't there, her second was realizing that they weren't people, and her third was acknowledging either of those facts.

Able to see bankai spirits!SI-OC.
All those years of playing the cello left her unprepared. As much as it pained her to admit it, she should have picked the flute. SI-as-Tayuya. SI-Tayuya/Shikamaru. Tayuya/Kimimaro sibling relationship.
She was the older, questionably civilian sister to one Haruno Sakura & she had no desire whatsoever to be a Shinobi.

Her chances at peace in the Naruto world as a nondescript member of the Kurama clan were screwed because apparently not even the Uchiha could keep it tucked in their pants. Perfect examples of self control and discipline her little half-blood ass! SI-OC/Sasuke. Half Uchiha!Oc. Genjutsu Kekkai Genkai!Oc

Out of all the kekkei genkai she would have liked to get, the eyes of Samsara wouldn't be her first - or second - choice. So naturally, that was the exact one she got. SI-OC/Itachi. Uchiha!SI-OC. Rinnegan!SI-OC.
Her new father was the Shoten shop keeper from that one anime with the swords. Shimei could only wonder what woman was crazy enough to get it on with Mr. Hat n' Clogs? Because really, Kisuke Urahara was NOT father material. SI-as-Urahara's-daughter.
Even Sea Kings could reproduce - Jupiter knew that from experience and pretty soon, her poor human father would know it too. SI-OC!As Shanks' Daughter with a twist!
Spanish for "small box", a term she had taken to calling the giant cage in her stomach because nothing pissed Kurama off more than saying that the almighty Kyuubi no Yuko lived in a four dimensional piece of cardboard.

She knew that mixing Uchiha blood and Hyuuga blood was "supposed" to result in the child having the Sharigan in one eye and the Byakugan in the other, but the theory of genetics disagreed. Guess who was right? Uchiha/Hyuuga, Dual Dojutsu-SI-OC. AU. Itachi/SI-OC.
