1863 - As political discord erupt into violence, the Tokugawa Shogunate sends a force of masterless samurai called the Roshigumi to Kyoto. However, assassination has split them into two opposing factions: the stronger is led by the brutal Serizawa Kamo and the lesser by the more honorable but less assertive Isami Kondo.
