Intro. Blue Lock is being threatened with ending due to lack of investors and so there will be a friendly match of Blue Lock against the U20 of the Japan national team and if Blue Lock loses it is erased forever but if Japan U20 loses the players of the U2 national team, players from the Blue Lock project will come (Except Itoshi Sae and Isagi Yoichi)

Blue Lock vs. Japan U-20
