Kuroda Nagamasa
Mitsunari was a leader of bureaucrats in Hideyoshi's government, and was known for his unbending character. Though he had many friends, one of them is Ōtani Yoshitsugu. Mitsunari was on bad terms with some "daimyōs" that were known as good warriors, including Hideyoshi's relatives Kuroda Nagamasa and Hachisuka Iemasa. Additionally, the young warrior Kobayakawa Hideaki developed a grudge against Mitsunari as a result of rumors spread by Tokugawa Ieyasu. Toward the end of Taiko Hideyoshi's life, Hideyoshi ordered the execution of his heir Hidetsugu and the execution of his family, leaving his new heir to be the extremely young child, Toyotomi Hideyori.
