Profile: After being killed in a gas explosion in his backyard, Ryo's soul was sent to his five-year-old body by The System, where he learns that The System cured his previously incurable disease. So with a second life and a healthy body, Ryo is determined to experience everything he once missed and devote himself fully to the sport he loves.
Football:
Favorite position – Attacking Midfielder
Favorite national team – Japan
Favorite club – none
Favorite player – Zinedine Zidane
Family: (Aoyama)
Older brother – Ren
Mother – Yuuki
Father – Kazuo
Traits: He is quite careful and calculating, especially when it comes to football, but he loves having fun more than anything. He puts his full effort into things he enjoys, but he won't waste his time doing things he hates.
Even in his second life, he looks up to and respects his brother, affectionately calling him Ren-nii, though that doesn't stop him from teasing him whenever he gets the chance.
He can never decide whether katsudon or tonkatsu ramen is his favorite dish, but he's certain that pork is his favorite protein, especially when it's grilled or deep-fried. He also has a notable sweet tooth.
