Yuzuru checked his own "status panel" and found that his attributes had barely improved at all... But that was only natural, since Kakashi had never been a ninja known for his "stats."
Getting a change in one chakra nature from him was already quite good. As for Chidori, it was indeed a highly advanced jutsu with tremendous killing power. However, it placed too much emphasis on high-speed thrusts and needed to be used in conjunction with the Sharingan to achieve its full effect.
Otherwise, it was merely an incomplete technique. If the user couldn't combine its straightforward linear charge with keen perception and nimble changes in direction, they could easily end up suffering a thousand injuries to deal a hundred.

Yuzuru thought about it for a moment, then retrieved the Mangekyō Sharingan from Kakashi's eye socket.
There was no need to describe the "retrieval" process in detail. It had nothing to do with delicate medical surgery; it was crude, even somewhat grotesque.
"Now here's the question: can I take an eye like this out of the instance?"
It didn't seem possible. After all, an eye was a "physical object." If Yuzuru could take it out of the instance, that would mean he could take things like the Scroll of Seals out too. The logic was the same.

This Mangekyō Sharingan, taken from Obito Uchiha, possessed a rare
