Resistance

Knife in hand, Itachi stepped in close. The man rose up, and caught Itachi
in his gaze.
Sharingan.
Without flinching, Itachi squarely accepted the surge of chakra emitted by
Tekka’s eyes.

“Wha—” Shock crept onto the face of his target. He appeared surprised
that his visual jutsu didn’t work. And then, in the next instant, he saw the
pattern in Itachi’s eyes, and the look on his face changed to one of chagrin.
“I-impossible! Mangekyo!”

Tekka’s stomach swallowed Itachi’s blade. He thrust it in deeply, all the
way to the hilt guard. No blood gushed out, not with the sword still in place.
Their faces were so close that their noses were almost touching.
“You all have the bad habit of underestimating your opponent’s abilities.”

“Itachi ...” Blood flowed out from between Tekka’s clenched teeth.
As Itachi leapt back, he yanked his sword free. An ocean of blood wet the
tatami mats; he was not caught by even a drop of splash-back.
Right hand thrust up, clawing at empty space, Tekka collapsed. “Th-they
won’t forgive you, Itachi.” Those were Tekka’s last words.
Itachi turned his back on the body, and sheathed his sword. “I wasn’t
asking for forgiveness.”
