It also allowed them a range of vision beyond that of the average ninja. That the rock was behind him made it more difficult, but her look of intent in his direction accompanied by his own keen senses caused him to throw his own Susano'o up around him as he ducked. This sheltered him just enough to avoid serious damage.

With the spell negated, the need for the sword cleared. The desire had been so unlike him that it didn't take much thought to come to the conclusion that his mind had been influenced again. Again. It really upset him that such a thing could happen so easily here. Still, his judgement had been clouded enough. He couldn't allow himself to get angry on top of that.

He had to wonder if it was possible to catch this creature in one of his illusions. Something simple such as displacing his location could work, and she had already looked in his direction so catching her eyes shouldn't be difficult.

Should he keep her attention on him with further attacks, or should he help with the mess the others had made? Itachi was still used to being a solo operative, so he worked on trying to get her to face his way again, shooting several small birds of flame at her from different angles.
