Kunais

In amongst the close-standing trees, Sasuke had hidden targets marked with double circles. And quite splendidly— Itachi couldn’t see a single one of them. “All right, Itachi,” Sasuke urged him in a spirited tone, unable to hide his excitement.  Nodding, Itachi grabbed his kunai. Once he had wedged one in between all his fingers, he had exactly eight in his hands. Eight iron claws sticking out from loose fists.

He lowered his face, and focused his mind just a little. He then poured the
chakra built up in the depths of his stomach into his eyes.
Sharingan.

The breathing of the trees grew restless at once. In the rumbling pulsation
of writhing life, he saw small circular foreign objects. Eight of them.
Itachi let out a small breath, and then he kicked lightly at the ground. In the
air, his head and his feet traded places. With his body upside down, his center
of gravity pointed downward and stretched out, stabilizing his posture. And
stabilizing his posture increased the precision of his control over his kunai.
He closed his eyes and imagined the eight targets in his mind. There were
two that he couldn’t reach from this position. The one knocked over artlessly
behind the front of the enormous rock was going to be the most trouble.

First, he threw the four blades in his left hand in a single motion. All
unerringly pierced the four targets in relatively easy locations.
Next, the two kunai clutched between the thumb and middle finger of his
right hand. These also dug into their intended targets without incident.
Two left.

Itachi’s body was still in the air. Not even a second had passed since he
leapt up from the ground.
He switched the kunai held between his middle and ring fingers to his left
hand. Now he had one kunai in each hand. He waved both arms and threw the
kunai at the same time.
The trajectories of the two blades overlapped. They collided in midair with
a sharp clang, and then bounced off each other to fly off in unexpected
directions.

He landed, his sharingan glowing with a crimson light.
As he stood up slowly, he felt the presence of his brother before him.
Sasuke had hidden himself behind a tree to avoid danger, but now he popped
his head out suddenly. He seemed dumbfounded at Itachi’s skill in hitting all
the targets. Sasuke’s mouth hung open as he stared at the rock before him, the
location of the most troublesome target.

Naturally, Itachi hit that one too. He had made the last two kunai collide,
and changed their trajectories, to that end.
“Wow! You even nailed that target in the blind spot behind the rock!!”
Sasuke flew out from behind the tree. He was clutching kunai in both hands.
He was in such high spirits after that display of his big brother’s skills that he
was practically beside himself.
