I went back to chapter 7 where the meeting is. This is unfortunately not a time rewrite like I was hoping. In ch 7, among differences in timing and dialogue where she notices/sees Kaname first, Shuka is wearing black instead of white. (Timing wise only ch7 makes sense due to the statue being in mostly normal condition)
This is either a dream, or an alternate reality. If it’s an alternate reality, I really hope Shuka isn’t in danger that she can’t handle alone.
A private wish I have is that Kanames height is accurate, instead, this is future-Kaname who grew a bit taller. In other words, we have a future Kaname pulling a similar dream trick going into the past or n alternate world (only ways the statue is fine), meeting with the current world Shuka. In that case we will get a bit of brain-bending fun with time-travel which will explain Kaname’s choice in traveling back in time to warn Shuka... my guess would be something happen in the world of the Oni where the Greed begins invading the other world too, thus Shuka must stay and help them using Kaname’s future information...
I also don’t hope for that because it will mean current-time-Kaname and Shuka can’t reunite for a while...
