Role in Games
In Samurai Warriors 3, the stage is played by both sides: Toyotomi (Kai) and Date (Masamune Date).

In Masamune's story mode, the people of Oshu flock to his banner to form a revolt in Miyagi Province. First, he needed to defeat Hideie Ukita and Yoshitsugu Otani. This allows the Southeastern Garrison gate to open to the advancing rebels. Kotaro Fuma appears with doubles and advances on Masamune. Despite Masamune thinking that he was working for Hideyoshi, Fuma stated that he was "tending to a stray kitten Ujiyasu left behind". Kunoichi arrives in the battle, heading towards Magoroku Saika before he shoots someone's eye out. Yukinaga Konishi also arrives with reinforcements for the Toyotomi Army. Yukimura Sanada arrives at the south to help lady Kai after Kunoichi is defeated, after which Masamune scolds Magoichi Saika for letting her escape. Mitsunari Ishida arrives as well with more troops. Reinforcements from the enemy keep coming and coming, so Magoichi advises Masamune to take the fight straight to the top. Hidetsugu Toyotomi and his allies arrive to aid the Toyotomi army after Mitsunari arrives, to which Masamune remarks that the Toyotomi seem to have an unlimited amount of soldiers at their command. He rushes up to the main camp and defeats Kai. However, he hates that he doesn't know how many times would he would have to repeat this charade. He goes to Hideyoshi, and is honored. A document shown by Kanbei Kuroda has the Date seal, but Masamune knows it is fake because there is no needle hole in one eye of the bird.

In Kai's story, Akihisa Kashiyama, Akanaga Kashiyama, and Shigenobu Muyari begin the battle by attacking the Toyotomi main camp to take the land back. Her father Ujinaga Narita is surrounded by rebel forces. Harunobu Kasai and Yoshitaka Ōsaki, the rebel leaders, must be defeated before Ujinaga's health is reduced to half. Kunoichi and Kotaro Fuma arrive as reinforcements for your team. After Kunoichi saved Ujinaga, Kai shouted to get off her father. Since it was too dangerous in that spot, Ujinaga planned to meet with Nagachika Narita. Yukimura Sanada arrived to aid Lady Kai later on. Yukimura targeted Magoichi Saika and began to rush towards him. Magoichi advises Kai to leave, but is defeated. After defeating all enemy officers, the Peasant main camp's gates opened. Masamune Date appeared there, and has to be defeated. After his defeat, she keeps in mind that Masamune shakingly said that she knows that she has what it takes to win the battle against him.
