Kamishini: Severing Blade

This technique allows Arui to run his Severing Void technique through his katana. This transforms his already sharp katana into a practically unblockable sword of unfathomable sharpness, being able to cut through chakra itself with relevant ease. Furthermore, due the wild and alternate yin or yang nature every second, it can cause objects it touches to disintegrate on contact due the unstable influences running through it.

This jutsu is powerful enough to slice through a lightning-powered chakra flow technique when on full power.
