Movie
Description
Emerging from a childhood as Matsudaira Takechiyo marked by political vulnerability and hostage experiences under the Oda and Imagawa clans, Ieyasu Tokugawa developed a foundational understanding of power dynamics and alliances. His character undergoes significant evolution; initially wielding the double-bladed spear Takechiyo, he shifts to brass knuckles by *Sengoku Basara 3*, adopting a close-combat style centered on charged physical attacks. This change symbolizes his transition from reliance on external support to self-reliant leadership. His elemental affinity transitions from lightning to light, reflecting his growing ideological focus on unity and hope.

Initially aligned with Oda Nobunaga and later Toyotomi Hideyoshi out of necessity, Ieyasu breaks from Hideyoshi upon witnessing his descent into tyranny and corruption. Hideyoshi's death leads Ishida Mitsunari, Hideyoshi's loyal retainer, to falsely blame Ieyasu. Despite his innocence, Ieyasu deliberately accepts Mitsunari's hatred, lying about his involvement to give Mitsunari a reason to live and channel his grief into purpose. This underscores Ieyasu's willingness to shoulder others' animosity for a perceived greater good. He subsequently forms the Eastern Army to oppose Mitsunari's Western Army, seeking to unify Japan through bonds of trust rather than force, focusing his military campaigns on recruiting allies sharing his vision of lasting peace.

In later conflicts, particularly leading to Sekigahara, Ieyasu grapples with internal conflict regarding his methods, questioning whether using warfare to achieve peace fundamentally differs from the oppressive regimes he opposed. Despite these doubts, he persists in advocating for unity, urging rival warlords like Takeda Shingen and Uesugi Kenshin to cease hostilities and join his cause. His conviction temporarily halts their feud, demonstrating his growing influence and moral authority.

During the climax in *Sengoku Basara: The Last Party*, Ieyasu works to dismantle manipulations orchestrated by Tenkai and Ōtani Yoshitsugu, who frame him for atrocities to turn the nation against him. He confronts Mitsunari at Sekigahara, attempting to dissuade him from vengeance. In a critical moment, he intercepts Date Masamune's lethal attack intended for Mitsunari, sacrificing his own safety to prevent bloodshed and demonstrate his commitment to reconciliation. Following Oda Nobunaga's resurrection and defeat, Ieyasu again invites Mitsunari to join his efforts. When refused, he challenges Mitsunari to a duel, not as hostility but as a means to forcibly align Mitsunari's strength with his vision for the country. Concurrently, he supports Sanada Yukimura's succession as leader of the Takeda forces, endorsing the next generation's role in maintaining stability.

His character arc concludes with an unresolved rivalry against Mitsunari and a continued commitment to unify Japan, accepting ongoing conflict as a necessary path toward his goal of enduring peace through interconnected bonds.
