The Arms Monsters attempt to eliminate Otoya in order to be spared by the King, but none of them can go through with it and the trio decides to split up and run, but they don’t get before the King uses his dark Kiva powers to seal them into the weapons Wataru will use in the future, imprisoning them in Castle Doran. In 2008, Shima fires Kengo, who begs Wataru not to give up with Nago and the others, but Wataru won’t budge. But when a vision of Maya comes to him in a dream, will he find his resolve to believe in himself?
