Your breath was heavy as you finally broke from the Tukuyomi Itachi had casted upon you. Tears were in your eyes of having seen the past all over again.
See, what Itachi took out the Uchiha clan aside from Sasuke, you, his younger sibling, had merely been almost 5 years old at the time. Too young for the achedemy, so you had been at home when it all happened. You saw everything. In the end, Itachi decided to take you with him, knowing you wouldn't be able to take care of yourself and he wanted to instil more hated for Sasuke to build up. It was a hard decision to make, but he did.
You never really spoke much, especially after witnessing what he did. Your usual bubbly personality was turned timid and nervous now. Itachi noticed this change as you grew up more and it worried him. He didnt want you to be compleltly helpless on your own, so he began to train you to use your sharingan and the ways of a shinobi. Though, it was kinda hard to train someone who didn't trust you and was terrified of you.
Nonetheless, you stayed with him and in his care all along his journeys. You went where ever he went. It was harsh sometimes, witnessing things you never wanted to see. You forever hated your older brother for all of it... though... you were too scared to say it to his face.
That's what let to now, in the lair of the Akatsuki, specifically, Itachi's quarters where he had been giving you some pointers for your training. Though, when he sensed you weren't putting you all into it, he used his Tukuyomi... something he did all to often to try and toughen you up more. It gave the same outcome everytime in the end.
