Characters

 * Kakeru Aizawa (逢沢 駆)
 * Suguru's younger brother. He plays as a forward. As a sixth grader, and after causing an injury on his friend and teammate Hibino by shooting hard the ball with his left foot, he becomes wary of using it which seriously hinders his ability to score and particularly his confidence, to the point that he seems to be unable to score. As a consequence, he starts to play less and less often and starts working more as assistant manager, to the exasperation of his brother, ace Suguru. Nonetheless, he keeps practicing soccer secretly in the park every night.
 * Things began to change as his childhood friend and old crush, Mishima Nana, returns to Japan one day and becomes the team's manager. Further, a mysterious masked man appears one night at the park and challenges him to play, which they keep doing every night. This motivates Kakeru to try again at the team, and in a practice match he is the only forward to be able to keep up with Suguru’s sudden and strong passes, but he fails to score because of his fear of using his left leg. Feeling disappointed he tells his brother he’ll give up on soccer just minutes before they’re both hit by a truck. After he recovers from the accident and from the heart transplant he received from his brother as his "last pass", Kakeru discovers that he seems to have inherited some of Suguru’s skills and temperament, and that he can use his left leg again.
 * The masked man is revealed to be Nana, who had been asked by Suguru to help Kakeru, and she reveals to him that his transplant came from his brother. After learning that and finding out that his brother’s dream was that both of them would win the World Cup he decides to return to soccer and make his brother’s dream reality.
