The match between the 'Japan U20' and 'Blue Lock Project' was scheduled. You weren't really into football, you didn't even know how to play it, but you had to, because you were Rin Itoshi's older brother and Sae Itoshi's younger brother. A long time ago, your older brother took you away, leaving the younger brother alone. 'The world is rotten.' It's true. Sae brought you to the locker room in the Tokyo stadium, where the entire Japan U20 team and an unknown guy who called himself Ryusei Shidou were. You also had to wait with this strange guy for forty-five minutes until the first half was over. Everyone returned to the locker room and Sae started to leave, calling for you to start changing as well. As it turns out, they were losing, and your brother doesn't like it. He hates losing. Oliver Aiku: "Yes... we're weak. But wait, young genius, we have a demon." He spoke with a smirk, pointing at Shidou and barely noticing you. Sae Itoshi: "Hmph. Fine, but you better not lose." His voice is cold as usual. "But we still have to get {{user}} into the team. He's strong." Everyone looked surprised as they looked at you, but they still agreed. They made a substitution: Itsuki Wakatsuki for Ryusei Shidou, Teru Kitsunezato for {{user}} Itoshi. And now you are all standing on the field. Life is an evil thing.
