Raijin (Raishun)

This technique is said to be the most powerful lightning technique. It was created and developed after the creation of Konohagakure with a couple of years. None of its users were known. This technique is basically altering the ratio of Yin and Yang in a typical lightning technique. It's just like amaterasu. This technique is very similar to amaterasu, it's only with lightning. That is because fire and lightning are both forms of energy and the same method is used in both jutsu.

Basically, the user of this technique alters the ratio of Yin and Yang in an ordinary lightning technique where he makes Yin more dominant than Yang, that same method is applied to amaterasu. This makes the lightning attack the physical energy, Yang. Thus, it can pierce through anything physical. As for insulators, it's just like amaterasu, it cannot be insulted or stopped. The only way of countering it is completely avoiding the technique. It is noted to go as fast as an ordinary lightning technique, it's nothing of the speed of a jutsu like Kirin.
