Itachi swallowed the words that popped into his head and turned around to
look at Madara. There was no way to know what emotion was on that face,
covered as it was by a mask. His body, cloaked in a black coat that reached

“You don’t need to worry about me.”
“I’m not worried. It’s a natural arrangement to properly execute our

“Don’t patronize me.”

didn’t have time to glare at Madara here.
“Whatever you want.”
“I’ll see you again once it’s all over,” Madara said, and disappeared into
empty space.
Itachi took a small breath. Close your eyes ... He moved forward in the
darkness, seeking a new target.
