Vector Technique

Vector Technique (方等級の術, Houtoukyuu no Jutsu) is a technique that builds of the Repulsion Technique used by Kei Yotsuki. It is known to be an application of his Thunder Release or sound ninjutsu. This can be further empowered with his unique Sage Mode.

Overview
By using the Repulsion Technique, the user can modify its use for varying purposes, than just the standard repulsion (similar to Shinra Tensei). Instead, they can use it to manipulate the direction of objects coming their way, varying the degree of repulsion throughout to do this. They can also use a field to catch multiple objects, before repelling them all back at once. This technique also allows the user to repel substances, using them like weapons, such as the air or water.

Especially in Kei's case, this technique can be used in many more ways. It can be used very precisely to mimic control over something, allowing something to forcibly move. It can also work to manipulate direction on a large scale, or cause mini earthquakes or wind gales. It can also be used through his many lightning techniques.

By using it on himself, he can use it to enhance his taijutsu, in a way similar to Thunder School. He can also use it to achieve flight or a powerful shield, which uses the power of the opponent's attack against them. It also can be used to launch multiple things as well as through his em energy attacks.

This technique can also be used as large-scale repulsion.

Improvement
By using Denji Ryū's chakra, this technique becomes more powerful, as well as using Sage Mode.
