Area no Kishi

Believing himself to be useless at soccer, Aizawa Kakeru opts to become the manager of his school's soccer team, while his brother Suguru is its ace, and is even good enough to represent Japan. However, Kakeru may be harbouring a strong talent within himself that only Suguru can see, and the two often get into arguments over Kakeru's denial of his skills. Things are made more complicated with the return of Seven, an old playmate of theirs that Kakeru has a crush on. Join the brothers in their journey to the national and even international championships! -----from ANN
