The instant the black glove passed through the wall, Shisui did not attack the hand.
His first kunai struck half a step in front of the wall.
Wire unfurled with the kunai, sealing off the area around the bait box.
If the intruder only reached out to take it, the wire would tighten the moment the box moved.
If he stepped through the wall entirely, the chakra mark on the kunai could record where he actually set foot.
The hand did not stop.
Its fingers passed through the wire as though through a shadow that did not exist.
Then came an arm, a shoulder, and half an orange mask.
The wall did not crack.
The Barrier did not fluctuate.
A man simply walked out of the intact stone wall.
At the third observation point, the Hyuga jonin called out in a low voice, "His chakra is still there, but his physical structure is fading!"
The Byakugan could see him.
Yet it could not determine whether that body was still in the current space.
Shisui's second kunai had already reached the Masked Man's neck.
The blade passed through without resistance.
There was no blood.
Nor was there any sensation of striking something solid.
The lone eye behind the mask slowly turned.
Its three tomoe were unmistakably clear.
The Sharingan.
Shisui's heart sank.
The Masked Man seemed to have been waiting for this very moment.
"Now that you've seen eyes like your own, aren't you going to follow?"
His voice was deliberately lowered, making his age impossible to discern.
He grabbed the bait box and began retreating into the wall again.
Shisui took a step forward.
That unfamiliar chakra was moving away.
If he used the Body Flicker Technique, he might be able to follow behind the wall before the man vanished
