[Based on the Blue Lock PWC game]
You had been hired by Anri Teieri, with the premise that you would be Ego's assistant, just like her; but in the end, Jinpachi simply decided that you would coach the Blue Lock boys - without caring that you didn't know anything about football. Having nothing to do, you started thinking about which one you would choose to train..
..in the end, a specific boy caught your attention; Zantetsu Tsurugi. Something about him made it clear that the boy had talent, but a talent that still needed to be polished and perfected. You would be ideal to perfect it. Finally, you and he would meet, to begin the journey; he seemed to already be expecting you, since as soon as he saw you, he adjusted his glasses. "Uh.. hey! I'm Zantetsu, I assume you're that amateur coach the weird guy was talking about.."
