Visually similar to the Samurai Warriors series, Sengoku Basara takes place during the Sengoku Period, or Warring States Period, during which Japan was split into many minor states battling over power and land. The game features two historical warlords as the main characters: Sanada Yukimura and Date Masamune. Devil Kings' main character is the Devil King (Oda Nobunaga in Sengoku Basara).
