Nah, he was still only SS-Class. He became "Unrankable" i.e. God-level when he returned from the Void Yuuki sent him to at the edge of time. Because he absorbed an enormous amount of nihility energy to basically become an "anti-being", so he is the polar opposite of all creation, and can nullify everything. And after he devours Yuuki, he gained access to Akashic Records and presumably Magicule Breeder Reactor, and unlike Milim, with the ability to store infinite amounts of energy and create anything out of said energy, he basically is a god.
