Area no Kishi (エリアの騎士) ()

Kakeru and Suguru are brothers who both have a flaming passion for soccer. However, while Suguru becomes a rising star in the Japanese youth soccer system, Kakeru decides to take on a managerial role after struggling on the field. But due to a cruel twist of fate, Kakeru ends up reevaluating the role he has chosen. In hopes of one day being able to enter the World Cup by becoming a member of the national team, Kakeru trains harder than anyone else. He isn’t alone in this quest for glory, though. Kakeru's childhood friend, Nana, is a soccer prodigy of her own, with the wicked nickname “Little Witch”. She is a top-ranked player and is already playing for Nadeshiko Japan, the Japanese women’s national team. Nana's success gives Kakeru the extra push he needs to reach for his goals.
