25What Was She Thinking?
It's well known in the Naruto-verse that Itachi Uchiha is a different caliber of Shinobi. He's not like these other ninjas running around; he is extremely exceptional. One of the things that makes him so is his use of Genjutsu via his Mangekyou Sharingan, a Kekkei Genkai of the Uchiha
clan. In fact, this ability is so strong that a mere glance is enough to trap a shinobi in his illusion. Kurenai is an elite Jonin of the Village Hidden in the Leaves and is well aware of this. She should have known better than to try to play his game.
