Yūsumi Gugenka: Keitai Yū

When utilizing Yūsumi Gugenka, the user holds their arm towards the ground, causing black ink to converge on it in a manner similar to lightning striking a target before spreading out and forming a barrier around the user. This barrier is special in that it literally robs of their physical form and spiritual essence, before reinforcing the technique itself, making it form effective. It effectively uses attacks against it as well as its surroundings to promote and repair itself. By shaping the technique around his Susanoo, it made Sadao practically invulnerable.
