A 12 year old mischievous travelling companion. His mother is Japanese, making him half Japanese and half Chinese. He first met Mei Li and Mao when they found him passed out, due to hunger, in the forest (In the manga, he bumped into Mao after stealing food from people). He left his village when he was 10 so he can fulfill his promise of becoming a Super Chef. Although, during his two year travel, he didn't become one, so he pretended to be one when he returned to his village (which was moments before meeting Mao and Mei Li). He was soon found out when a cooking official said his Super Chef badge was fake. After finding out that Mao was a Super Chef, he made himself Mao's apprentice and decided to travel with him. He often teases Mei Li and constantly grabs her breasts, resulting in him being constantly hit by her. He may not be a cooking genius, but he knows more about cooking than Mei Li and is only somewhat average in cooking. Shirou often gets into trouble and also causes trouble for the other group members. He later becomes a chef-in-training at Yang Spring Restaurant.
