Guardic Gaiden

At the start of the game, Ryu Hayabusa is responding to an attack in his village as he rushes to a shrine where the leader of the attack was holed up in. Defeating him, the leader reveals that he was hired by a man named Totenkopf who was a smuggler who sells weapons to a variety of clients. Attempting to find out why would someone would steal the Dragon Sword, Ryu infiltrates the boat and kills Totenkopf, revealing a man named Mr. Tsin who he was selling weapons to in Hong Kong. Ryu defeats Mr. Tsin but not without being captured and brought to India where the person who wants the Dragonsword to start World War III reveals himself to be Shiragane, a demon capable of mind control and with the power of the Dragon Sword, can effectively have almost unlimited power in dominating over the minds of others. Ryu kills him and brings an end to another threat of the world.
