Mitsunari Ishida (Koei)

Mitsunari Ishida is one of the major characters in the Samurai Warriors series, originally appearing in Samurai Warriors 2.

History
Mitsunari is one of Hideyoshi's chief advisors, who specialize in securing supply lines. His mission allowed his lord to quickly assemble the armies, which allowed him to get a close range near Hideyoshi. When he assisted in besieging Yamazaki, he became familiar with Sakon.

Although Oichi initiated an uprising against their lords, during the Shizugatake period, Mitsunari was forced to prove himself to the untrustworthy and bitter Kiyomasa and Masanori. When he was fighting, Kanetsugu came to the court to judge which side had more virtues. Mitsunari persuaded Toshiie to stand up, General Uesugi would be impressed with the role of Mitsunari and then convince his master to join with Hideyoshi. When he meets Oichi, he says that if her husband is still alive, he can serve Nagamasa. To commemorate his wishes, she allowed her to inherit the land of her deceased husband after her death. Soon after, Nobunaga's son, Nobukatsu announced that he was a legitimate heir and fought with the master of Mitsunari in Komaki-Nagakute with Ieyasu. With the beginning of the siege, Mitsunari learned about his owner's desire for a happy place and met Ieyasu for the first time.

With Ieyasu being subdued, Hideyoshi continued to travel to Odawara Castle. Mitsunari previously introduced himself to Kanetsugu and Yukimura, who announced their friendship as a common goal. Hideyoshi eventually died after the land was unified, and Ieyasu collected the army as the ruler. In order to keep the Toyotomi family on their pedestal, Mitsunari and Kanetsugu cooperated to attack Ieyasu from both sides. After Kusegawa defeated the Eastern army, he commanded Western army to surround Ieyasu in Sekigahara. Learning these numbers doesn't always give unity or understanding, and Mitsunari gathers friendship and trust with an exciting speech after the victory.
