### Summary
The U-20 match is thrown into chaos as Sae Itoshi, declaring he's seen enough, makes a shocking substitution. He unleashes Blue Lock's explosive "demon," Ryuusei Shidou, onto the field as his chosen partner, anointing him "my little demon" and creating a terrifying new offensive axis. This move highlights the U-20 team's reliance on a Blue Lock product to fight Blue Lock itself. Off the pitch, the mood is lighter as Isagi's and Bachira's parents meet for the first time, while Chigiri's sister makes an appearance that catches Eita Otoya's eye. However, a fleeting glimpse into Sae's thoughts reveals a lingering connection to his brother Rin, adding a layer of emotional complexity just as Shidou's unpredictable presence threatens to shatter Blue Lock's chances.
