Now that he holds Kyoto, Oda Nobunaga finds himself the focus of enemies on all sides. Even the Shogun, who no longer needs his military assistance, turns against him. Oda marches north to quell the Asakura clan, only to be betrayed by the Azai clan leader, his own brother-in-law, who allies with his enemy and embroils Oda and his remaining true ally, Tokugawa Ieyasu, in the Battle of Anegawa. No sooner has he won a narrow victory than Oda launches into in an eleven year siege with the Ikko-ikki warrior monks at their mountain temple of Hongan-ji. Unable at first to turn that siege in his favor, he learns from it when facing a second group of Enryaku-ji warrior monks at Mount Hiei. Oda shows his true brutality by setting fire to the temple and ordering his troops to massacre all 20,000 inhabitants - men, women, and children.
