Ii Naomasa

Ii Naomasa (4 March 1561 – 24 March 1602) was a general under the daimyō and Shōgun Tokugawa Ieyasu, regarded as one of the Four Guardians of the Tokugawa.

During the Battle of Sekigahara on 21 October 1600, Naomasa was critically wounded by a stray bullet fired by Shima Sakon's unit. Though Yamauchi Taka exacted revenge on Sakon on Naomasa's behalf, Naomasa eventually succumbed to his wounds.
