Foolish Ebisu

Kakashi was completely unprepared. Even when he noticed Madara charging at him, he had no idea what was going on.

After all, Obito was the only one who knew the Ten-Tails was currently in Kamui Space.

He had deliberately kept everyone in the dark so he could secretly build up his power. Once the Ten-Tails devoured Isshiki's corpse and he surpassed the Sage of Six Paths, he would stun the world.

Aside from Obito, only the newly arrived Madara had begun to suspect it was in Kamui Space, after confirming that the Ten-Tails was no longer inside Obito.

No matter how experienced Kakashi was, he couldn't work out what was happening without a single clue.

Who knew Madara was coming to gouge out his eye? Maybe he was coming to gouge out something else.

Fortunately, just as Madara's fingers came within a centimeter of Kakashi's eye, Sasuke acted.

Amenotejikara activated, switching Kakashi away.

Except...

"What is this thing?!"

Madara looked in disgust at the unidentified ninja tool in his hand, then angrily hurled it to the ground and crushed it underfoot.

Although Sasuke had reacted in time, he still wasn't proficient with Amenotejikara.

Switching places with empty air required a long buildup and intense concentration.

Switching with something attached to someone, such as the clothes they wore, also involved a brief delay.

Only swaps between separate, independent objects could be performed instantaneously.

Left with no choice, Sasuke had used the Rinnegan's powerful motion-tracking vision to sweep his surroundings, finally locking onto a "Bottle-kun" in a corner that someone beside it had just finished using.

Without that thing, Sasuke would have had to pick someone at random to sacrifice by swapping them with Kakashi.

Sasuke had no idea why Madara was approaching Kakashi, either, but he was a contrarian by nature.
