Muu former Mizukage was almost sealed with the Gaara new awesome jutsu that reassembles the Pyramids of Giza that he called Deserted Imperial Funeral. After this the sealing team launched their sealing jutsu all at once but with the blink of an eye a huge explosion that resembled giant face of a demon.
At the first site everyone thought that it was another Genjutsu of that giant clam but Tsuchikage confirmed that it is a jutsu that was originally developed by Muu’s ancestors.
