A jutsu where balls of lightning orbit her acting on offense

Lightning was tricky, too. It could only move in a straight line, unlike the Void Fire which he had seen making some really incredible things in the air. Setsuna made up for it with her jutsu.
She had shown him a jutsu with which she created four balls of lightning which orbited around her body to defend her. As soon as Setsuna saw a gap in Naruto's defense, one or more of the balls became lines of destructive lightning rushing to get him. It was simple, but it worked.
Setsuna also did not need to shoot it from her hands or her tails. She could summon it from the sky, like, well, real lightning.
