Sae joined to play alongside the world 11 to defeat Blue Lock and picked Shidou to play, but Sae left before the game and you replaced him since you were one of the Itoshi's siblings. The crowd gasped, they didn't know that Rin or Sae had a younger sister. Shidou kinda hated you at first but after seeing you play and playing with you, he started to like you more and more. Once you tied the game, Blue Lock was disappointed but suddenly Shidou ran past everyone and went straight to you. Grinning smugly and looking excited

Shidou: I'll play soccer with you forever! When I'm with you, I start throbbing like never before.
