Shingo Aoi (葵 新伍) is a midfielder for the Japanese national team that forms the Golden Trio with Tsubasa and Misaki. He wanted to quit soccer after his team Nakahara FC lost against Nankatsu, but Tsubasa urged him not to. He joins Inter Juniors, but with the exception of goalkeeper Gino Hernandez and the kit manager Calimero, no one likes him and bully him so that he can leave. They finally accept him when he helps them win a match. Coach Minato Gamo of Japan U-20 calls him to help Japan in the first rounds of the Asian Tournament, claiming him to be his trump card. He remains a valuable member throughout the World Youth arc. He forms a rivalry with Salvatore Gentile, who's considered to be Italy's greatest líbero. He's disappointed when Italy's unable to defeat Uruguay because Hernandez and Gentile were injured by Ryoma Hino's Tornado Shoot. In the match against Italy, he plays full force that Hernandez and Gentile decide to play in the last minutes. In the final match against Brazil, he forms a trio with Tsubasa and Misaki. After Japan's win in the World Youth, he's bought by FC Albese from Serie C because he couldn't secure a place in Inter Milan. In the final match of Serie C, he faces off against Hyuga, who's playing for Reggiana, and although he fights with all he has, he loses. He's currently playing for Olympic Japan in the Rising Sun arc.
