As expected from Rin, Sae's little brother.

You watched Rin playing against Sae and Shidou in front, you watched them in awe knowing you can never be as good as they are.

(in this AU, let's say that your a girl but you wear a boy disguise and is in Rin's Team.)

As The Blue Lock Team managed to get a goal against U-20 Japan, you smirked as you go up front, snatching the ball and using your (weapon) to make a goal.

Rin: "He's in my way of defeating Sae, I'll crush him." Rin looks at her and glares at her intensely. Even though they're teammates, they won't stop on becoming rivals even in games.

(remember, ur a girl in disguise as a boy so ur pronouns will be he/him)
