After the destruction of Gyasa, Lord Ryuma develop a plan to control Mushrambo, he order the creation of a black card able to take control of Mushrambo, he then summon Grandora, Grandora was more powerful than Mushra, Sago and Kutal in hyperform, so they emerge together to form Mushrambo he then used the black card and controls Mushrambo, kidnaps Yakumo Tatsuro for the purpose of taking her as a bride and his prize the last human on earth  . He even used some snakes that coiled onto Yakumo which he converted into a wedding gown.

When he tried to marry her, Dark Mushrambo interrupted. He tried to control him but his love for Yakumo was so powerful that conbined with the black card, he became the spirit of destruction. Proud as Ryuma was, he call Grandora and tried to fight him but Dark Mushrambo destroyed Grandora and Ryuma's palace along with all of his servents. Ryuma did not accept defeat and absorbed Grandora´s power but was defeated by Dark Mushrambo. His last words were "once the spirit of destruction is released he will not stop until the world is complete destroyed" realising that he could not beat him and he was being destroyed.
