Description
Oda Nobunaga emerges as a pivotal figure within the narrative, initially challenging the established order. Born in 1534 in Owari Province, his unconventional early actions earned him the derogatory moniker "Fool of Owari," stemming from public displays like wearing improper clothing and perceived disrespect during his father's funeral. Despite this inauspicious beginning, he consolidated control over the Oda clan after his father Nobuhide's 1551 death, overcoming succession disputes and internal rivals through decisive military actions, including defeating his uncle Oda Nobutomo at Kiyosu Castle. A crucial political alliance was forged through his marriage to Nōhime, daughter of Saitō Dōsan of Mino Province.

Nobunaga's military prowess gained widespread recognition following the 1560 Battle of Okehazama. Facing overwhelming odds against Imagawa Yoshimoto, he executed a daring rainstorm ambush, decapitating Yoshimoto and shattering the Imagawa forces. This victory marked his ascendancy and secured an alliance with Tokugawa Ieyasu, formerly a hostage. He expanded his territory, capturing Inabayama Castle in Mino in 1567 and establishing Gifu as a strategic base. Nobunaga supported Ashikaga Yoshiaki's bid for shogun in 1568, marching on Kyoto to install him, but their relationship fractured, leading Nobunaga to expel Yoshiaki in 1573 and effectively end the Ashikaga shogunate.

His rule blended ruthless suppression with innovation. He famously destroyed the Enryaku-ji temple complex on Mount Hiei in 1571, neutralizing a potent religious and military threat. A decade-long conflict against the Ikkō-ikki culminated in their 1580 surrender at Ishiyama Hongan-ji after imperial mediation. Nobunaga revolutionized warfare through the large-scale tactical use of firearms; at the 1575 Battle of Nagashino, his forces decisively defeated the Takeda cavalry using rotating volleys of arquebus fire behind defensive palisades. Economically, he abolished toll barriers and guild monopolies to stimulate commerce. Culturally, he patronized the arts and constructed the imposing Azuchi Castle in 1576, symbolizing his power and ushering in the Azuchi-Momoyama period. His pragmatic openness to foreign influences included accepting Jesuit missionaries and bestowing samurai status upon his African retainer, Yasuke.

The persona "Demon King of the Sixth Heaven" (Dairokuten no Maō) reflected his relentless campaigns and merciless tactics against opponents. He demanded absolute loyalty from retainers, viewing them as instruments for his ambition to unify Japan. This bred resentment, notably from Akechi Mitsuhide, who disapproved of brutal acts like the annihilation of surrendering opponents at Nagashima. The culmination occurred on June 21, 1582, at Kyoto's Honnō-ji temple. Mitsuhide launched a surprise attack, trapping Nobunaga. Facing defeat, Nobunaga committed seppuku as the temple burned. His death came just before achieving complete control, though his conquests secured roughly half the country.

Within the broader story focusing on the Sanada clan, Nobunaga functions as a powerful external force shaping their destiny. After his victory over the Takeda clan, the Sanada, led by Masayuki, initially served under his command. The chaos following his death at Honnō-ji created opportunities and perils for the Sanada, forcing them to navigate shifting alliances and power struggles between his successor Toyotomi Hideyoshi, Tokugawa Ieyasu, and others. His legacy as the first unifier established the conditions leading to the Tokugawa shogunate's eventual dominance, directly impacting the Sanada brothers, Yukimura and Nobuyuki, who found themselves on opposing sides during the Sekigahara campaign and the Siege of Osaka.
