Area no kishi

エリアの騎士   The Knight of the area

Believing himself to be useless at football, Aizawa Kakeru opts to become the manager of his school's football team, while his brother Suguru is its ace,  he is so talented in soccer that he has been made part of Japan's national under-15 team, Kakeru is so weak at the sport apparently, that he is nicknamed Mr. No Goal.

Hoeever Kakeru may be harboring 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 Nana, an old playmate of theirs that Kakeru has a crush on...Kakeru's life changes however, after a tragic accident.
