Ieyasu Tokugawa from the Samurai Warriors anime is depicted as one of the three great unifiers of Japan, a figure destined to bring an end to the tumultuous Sengoku period. First appearing as a non-playable character in the original narrative, he later steps into the spotlight as a central figure who ultimately closes the era. His character is defined by a profound and unwavering commitment to establishing a lasting peace, a goal that often requires him to make difficult and morally complex decisions.

His background is rooted in the chaos of war. Born into a minor ruling family, he spent much of his early life as a political hostage, an experience that forged his patient and calculating nature. Initially serving the Imagawa clan, he famously switched his allegiance to Oda Nobunaga after the Battle of Okehazama, becoming a key ally. Following Nobunaga's death and a period under the rule of Toyotomi Hideyoshi, Ieyasu emerges as the most powerful figure in the land, setting the stage for his pivotal role in the series.

In personality, Ieyasu is the embodiment of patience, a trait he frequently extols as the key to success, believing that a slow and steady approach wins the race. He is often portrayed as a reasonable and caring leader, famously describing his loyal retainers as his greatest treasures. This kindness is balanced by a hard-edged pragmatism; he is a well-intentioned extremist who understands that creating a peaceful world may require him to sacrifice his own benevolence and become a ruthless demon when necessary. His detractors see him as a sly and manipulative old raccoon dog, a tanuki, reflecting his cunning political strategies.

Ieyasu's central motivation is the dream of a unified Japan free from endless warfare. This dream is the engine for all his actions, from forging strategic alliances to leading massive armies into battle. His role in the story is that of the ultimate successor, the final winner of the Sengoku period. He is positioned as a concluding force, often contrasting directly with idealistic but ultimately tragic figures like Sanada Yukimura or his rival Mitsunari Ishida. His story culminates in the decisive Battle of Sekigahara, where his Eastern Army defeats the Western Army, and the final Siege of Osaka, which extinguishes the last embers of resistance.

His key relationships are complex and deeply tied to the game's narrative arc. He shares a profound yet complicated bond with Oda Nobunaga, whom he initially serves as a loyal ally. With Toyotomi Hideyoshi, he transitions from a rival to a subordinate, biding his time until Hideyoshi's death. His most significant adversarial relationship is with Mitsunari Ishida, the embodiment of Toyotomi loyalty, whom he must defeat for his vision to prevail. He is also the master of the legendary shinobi Hattori Hanzo and the commander of the mighty Honda Tadakatsu, both of whom serve as his most trusted instruments of war.

Over the course of the story, Ieyasu undergoes notable development. Early portrayals depict him as a somewhat smug and even cowardly leader who relies heavily on his talented vassals. As the narrative progresses, he takes a level in badass, growing into a capable and respected general. He matures from a man who mourns the loss of his soldiers into a leader hardened by sacrifice, fully accepting the burden of his ambition. Different story paths even explore what-if scenarios where his betrayal is the catalyst for major historical events, showcasing his ruthless side.

In battle, Ieyasu is known for his distinctive and powerful abilities. His primary weapon is an innovative spear that doubles as a cannon, allowing him to strike at range with fire or energy blasts. His fighting style reflects his mantra, often described as a mighty glacier that is slow but devastatingly powerful. He commands the fire element and can unleash powerful Musou attacks that demonstrate his authority and strength on the battlefield.
