Position
He's a goalkeeper (World youth arc, chapter 61, page 17).

Abilities
He is described as a genius keeper, but he followed a special training where he apparently had to stop a lots of skywing shot from Santana and Roberto to have perfect countermeasures against Hyuga's raiju shot (World youth arc, chapter 62, pages 10-11, pages 90-91).

Coming out of his goal
He can come out of his goal to be on the opponent's shooting course (World youth arc, chapter 63, pages 14-15).

Two handed catch
He can easily catch with two hands a tornado shot from Hino, though the distance wasn't specified (World youth arc, chapter 61, page 17).
He can catch with two hands a skywing shot from Santana, though the distance wasn't specified (World youth arc, chapter 62, pages 10-11).
He can catch with two hands a raiju shot from Hyuga unmarked from outside of the penalty area (World youth arc, chapter 62, pages 88-91).
He may not be able to properly catch a twin shot done during a double overhead from Tsubasa and Misaki (World youth arc, chapter 63, pages 12 to 15).

Saving
He may be tricked by a curve (World youth arc, chapter 63, pages 46-47).

Reaction
He can react to, but not stop, a flash raiju shot from Tsubasa, Misaki and Hyuga (World youth arc, chapter 63, pages 36 to 49).
He may not be able to react to Tsubasa's 2 steps overhead at point blank range (World youth arc, chapter 63, pages 138 to 143).

Captainship and leadership
He can give directives to the defenders, although it wasn't to improve the defense (World youth arc, chapter 62, pages 88-89).

Fighting spirit
He is ready to sacrifice his hands and whole body to stop a shot (World youth arc, chapter 63, pages 46-47).

Injury resistance
A twin shot done during a double overhead from Tsubasa and Misaki may make his arms numb (World youth arc, chapter 63, pages 12 to 16).
