Sengoku BASARA

With the death of Nobunaga, Japan is thrown into a mist of battle once again as the many warlords of the nation try to unite it as one. But can any succeed when faced against Nobunaga's sucessor, Toyotomi and his lust for power thats sets the flame for war as he try to take over the world fulfilling his ambitions of absolute power?

It is a time of civil war, and the young warlords running Japan are... hopelessly stupid. This manga takes place in the Sengoku (Warring States) Period in Japan, and is based off the game Sengoku Basara, otherwise known as Devil Kings in the US. Sanada Yukimura, who serves under his master Takeda Shingen, hopes to accomplish his master's dreams of a united Japan. However, he is faced with many obstacles, forcing him to battle against many powerful warriors with the same ambitions. One of these men is Date Masamune; with his flamboyant attitude and his ideal "fun," he stirs up uncontrollable anxiety within Yukimura that draws him into the heat of battle...

Based on the video game.
