Ieyasu Tokugawa is a character in the Samurai Warriors series. He is the founder of the Tokugawa clan.
Ieyasu is the proud lord of Mikawa and an old friend of Nobunaga. For political reasons, he was a former ally of Yoshimoto Imagawa. When Imagawa was ambushed in Okehazama, Ieyasu and his people chose to work with Oda. He plans to occupy the land by relying heavily on his vassal and resourceful shinobi, Hanzō Hattori.
Ieyasu had formed an alliance with Nobunaga and helped his allies by attacking Anegawa's large Asakura army. Then he tried to attack Shingen, but he became the victim of the veteran's ambush. In order to escape life, Ieyasu mourns the loss of his vassals for his safety. Tadakatsu assured him that they were dead, protecting the peaceful world envisioned by his master and strengthening his determination to be healthy. Shingen and Nobunaga eventually passed away, and Ieyasu became one of the two powerful people on the land. In order to resolve their differences, he challenged his rival Hideyoshi at Komaki-Nagakute. Although he won the battle, but Ieyasu believes that killing his opponent will only make the land into chaos again. Therefore, he kept his ambition and let Hideyoshi rule the time. When he assisted the western siege of Odawara Castle, he won Masamune as an ally.
After Hideyoshi's death, Ieyasu decided to put his plan into action and clash with Toyotomi's loyalist Mitsunari. After winning the battle of Sekigahara, Ieyasu became the shogun general and eventually united. The remaining Toyotomi loyalists united against him in Osaka Castle. He feared that his grip could cause the land to fall into chaos again, and he led his army to destroy them. With the land finally peaceful, Ieyasu completed his hard journey of unity. When Kanetsugu and Uesugi troops went straight to their place, Ieyasu and Ina were accidentally isolated from their allies. His enemies also include the Sanada army from Ueda and Yoshinobu Satake.
