Itachi's face contorted in a cold glare, which just as suddenly relaxed back to his usual unfeeling sharpness. However, the single moment of emotion did not escape the other three.
"Now, now, just what were you trying to do, Itachi-kun?" Her low tone made the mockery almost acidic. "Trap me in a Genjutsu? Maybe you intend to kill me?"
"Fool. You already witnessed my illusion, and you still believe you catch match me? Do not disappoint me with your stupidity, boy."
Itachi's eyes narrowed dangerously. The three black tomoe in his blood red orbs began to shift and merge together. Setsuna snorted.
"Don't bother. Even if you use your eyes, your illusions are still inferior to mine. And I'll prove it to you now."
