Traveling deeper into the Underworld, Ryu confronts Dagra Dai, who is nearly finished with the Archfiend's resurrection, and defeats him. As a last resort, the Infernal High Priest offers his life to Vazdah, and the Archfiend is reborn. Ryu takes down the monstrosity and heads to the surface with Sonia, but a drop of his blood from an open wound accidentally spills onto the fiend and revitalizes Vazdah, who ascends to the summit in its true form. Amidst an erupting Mount Fuji, Ryu squares off with the Archfiend in a climatic duel to decide humanity's fate and wins. Sonia and Ryu reunite and climb to the top of the mountain, sharing the sunrise together.
