Xu Shu (onyomi: Jo Sho) is a disciple of Sima Hui and an expert swordsman in his younger days. Avenging his friend with his blade, he gave up swordsmanship and decided to study after his arrest. He is friends with Zhuge Liang. He was known to have been a filial son, and cared deeply for his mother. In both history and in fiction, it is because of Xu Shu's piety that he chooses to leave Liu Bei for Cao Cao. His character's height in Kessen II is 180 cm (5'11").
