Suguru Aizawa is the older brother of protagonist Kakeru Aizawa and a widely recognized football prodigy. Firmly believing in his younger brother's hidden potential, Suguru dedicated himself to the pursuit of the ideal 'Knight of the Penalty Area.' Tragically, his life was cut short in a devastating traffic accident when he shielded Kakeru at the cost of his own life. His heart was subsequently transplanted into Kakeru, ensuring that his spirit and extraordinary skills live on within his brother — becoming the ultimate driving force behind Kakeru's return to the pitch.
