[Gender-Swap Story, Survival at All Costs, Conspiracy Theories.]
Ying transmigrated.
Not only did she become an orphan of the Uchiha Clan, she also became bound to a System.
While everyone else trained in chakra, she became a witch instead!
While everyone else wanted to become Hokage, she just wanted to stay alive!
As a transmigrator who knew the story inside out, Ying had only one rule:
Stay far away from the main cast, and even farther from the characters tied to the plot!
Especially Kakashi Hatake and Obito. The farther she stayed from those two, the better!
As long as she didn't get involved with them, she could avoid the plots where survival was all but impossible and safely grow stronger!
From then on,
To survive the massacre night nine years later, Ying had no choice but to pour points into her skills like crazy!
She even tried to set Shisui straight: "Don't believe in the Will of Fire. It's just brainwashing, a con to fool children!"
She even had to give the four-year-old Itachi some pointers!
Years later,
When the massacre night arrived and tragedy was about to repeat itself...
Ying pulled out the wand in her hand.
Ahem!
No, that's not right.
She pulled out a sword,
and the witch's wings on her back suddenly unfurled!
Facing the forces encircling Konoha,
the girl cried out:
"Today, my sword points toward the clouds piled high... I refine Gu, refine people, and refine Heaven!"
