Chakra stay with the soul.
If suki soul returning in the past, she should got her chakra's level with her EMS/Rinnegan.

usually I don't like stories with Sasuke or with Naruto being with someone other than Hinata but I like your first chapter so much I will follow in favorite and see where this goes

I like this idea, not bad writing either. Though if you wanted to put a cap on her power I would've suggested her chakra be not missing a quarter but maybe a quarter of her adult strength or lower or at least have Reningan sealed away or both. Anway I'll be paying attention to this story, good luck to you.

nice. very interesting

Good chapter interesting story

Yes! There is not enough time travelling Sasuke stories out there (or if they are out there they are either impossible to find or abandoned) and this is really well written, so its an extra special unicorn! I love how you've characterised her, those last two sentences were just magnificent, I hope it is forshadowing of her just giving zero fucks about keeping things on the down low and just going out and saving everyone's asses.

I really really want her to just walks out and straight up kill Orochimaru (not forgetting to take his sword of course). I just want her to badass start hunting down all the Akatsuki (I don't remember but has Asuma been killed by the Akatsuki yet? Or would she be able to just pop up in Konoha and just decimate the irritating immortal type dudes -Kakuza and Hidan or whoever- while everyone from the genin 9 just look at her like WTF).

Cause a BAMF female Uchiha is sorely required in the world, and you, you wonderful author, are doing us poor poor mortals a great favour.

Wonder how Suki will change things anyways keep up the great work!

Awesome and interesting, would love to see more from you!
