First Selection: Round-Robin Group League Match (一次選考「総当たりグループリーグマッチ」) - is the first selection of the Blue Lock Project.
Twenty-five teams are divided into five stratums or groups to perform a round-robin tourney; the top two teams of each stratum will move on to the next selection and the remaining three teams are expelled. However, the top scorer of each losing team will be allowed to advance to the next selection. Teams are ranked by their wins, losses, and amount of points scored; a win is 3 points, a draw is 1 point, and a loss is 0 points.
Only the teams who are able to build a foundation, understand and utilize their weapons, and turn "nothing" into "something" will be able to survive this selection and move on to Second Selection.
