"Nii-san, what are you-" the raven-haired girl exclaimed in shock.
Obito grimaced as he glanced at her, standing over the bodies of some Uchiha he'd just killed.
"Wh-What are you doing?! Why'd you kill them?! They didn't do nothin' wrong!" She cried out.
He sighed softly. "It's for the greater good, Miyu-chan. They were bad people."
"B-But they were nice to me! And th-they didn't hurt no one!" She insisted.
Crouching down in front of her, Obito patted her head. "The evilest people work behind the scenes. Don't trust anyone. Got it?" He asked, pinching her cheek.
She sobbed, wiping her eyes. "Mhm."
He turned away and discreetly nodded, eyes softening at the relieved face she made despite the tears escaping her eyes.
There was a pause before Obito used kamui on himself, looking at his little sister from the corner of his eye.
"I'm sorry, Miyuki."
