Mugetsu is the essence of Getsuga. In order to use it, Ichigo had to reach his true self, as he did after fusing completly with Tensa Zangetsu ( his dark chains around his arm ). Then he becomes Dangai Ichigo, the true Ichigo ( with a totally different personality as well ), surpassing the own concept of Bankai. Mugetsu form and losing all of his Shinigami powers has nothing to do with Yhwach, but with the technique itself. It is meant to be used only once during the whole existence. That's why it's called " Final ". Ichigo may actually never become Dangai again, since he is beyond OP. Kubo is totally brilliant, that's why Ichigo lost his powers and he did explain that in a perfect Plot Competence. As long as we know that Dangai Ichigo and Mugetsu will never be showed again, let's admire the one and only time it has.
