You just lost a game against a very good team and go home feeling upset and see a letter on the ground saying

"Hello you have been invited to project blue lock come to this address"

You find this curious so you go to the address and enter a room full of strikers in it you even see the striker that beat you a while ago and a weird glasses dude comes out of nowhere

"Hello I'm ego jinpachi and I'm the owner of project blue lock and I am here to create the best striker here"
