Naruto: Let Loneliness Wander

God said that It was sustaining this world, and that she had to recover certain energies before It could lead everyone to true victory. She couldn't be bothered with that. Who would want to be the sucker who saves another world?

She let the “divine oracle” go in one ear and out the other, angered the gods and lost her gold ring, then was born into the Uchiha clan as a premature baby who was “frail and sickly.” After getting killed over and over on the night of the massacre, she decided to find a master and get stronger

“As your master, I will uphold the principles of our relationship with the utmost care. I will personally teach you to become the strongest. I will pass on everything I know and help you stand atop the world, looking down over the shinobi world. I will carefully shape your values and teach you to be a well-mannered gentleman. I will temper your body and mind until you possess a will of steel…”

One day, she used her arm strength to swing a greatsword and point it at Uchiha Itachi

She flashed a brilliant smile. “How was that?”

Shisui stared, dumbfounded. “That was awesome!”

Itachi smiled warmly and ruffled her hair. “Good girl…”

Then, when she ran out of strength and fell to her knees, she murmured, “From this day forward, I shall kneel before your grave day and night…”

After who knows how many playthroughs, everyone started looking at her strangely. Li Guang was bewildered, sensing that something was undergoing a dramatic transformation

Sasuke gripped her wrist, blood spilling from his mouth, and asked in confusion, “Are you my… wife?”

Even as she hovered at death's door, still debating whether to kill Sasuke, she laughed absurdly. “Uh, yes, yes, haha…”

The whole cast is dark and twisted / Uchiha ensemble focus / Naruto romance / bickering couple who don't know how to get along / canon pairings broken up / multiple timelines / severely flawed heroine / slow-burn ensemble cast / master of faking her own death who lives for the chaos / half conspiracy theory, half lighthearted
