Eric, a French noble by birth, arrives in Genoa as an international student pursuing football. He rises to ace striker for the Sanpodestà Junior team, renowned for exceptional technique, powerful shooting, and his signature "Julian Shoot." Initially driven by intense national pride and a belief in playing for France's honor, he wields a sarcastic demeanor and looks down on others, particularly Hikaru, whom he deems less skilled or committed.

His younger sister, Catherine, studies ballet in Genoa and forms a romantic relationship with Hikaru. Eric frequently cautions Catherine against her perceived excessive optimism, reflecting his own serious, disciplined approach to life and sport. This relationship fuels personal tension alongside his competitive rivalry with Hikaru.

A pivotal moment occurs with Eric's rejection from the French youth national team, challenging his identity rooted in national representation. Following this setback, Hikaru invites him to join the newly formed multinational team, Jupiter Wings (J-Wings), dedicated to uniting global talent regardless of nationality. Eric accepts, marking a significant shift. His participation on the J-Wings forces collaboration with former rivals like Hikaru and the assertive Cesare Gatti, moving him away from elitism and individualism towards valuing teamwork and cross-cultural cooperation.

Competing in events like the Genoa Cup, Italian Youth Soccer Tournament, European Tournament, and Junior Champions Cup with the J-Wings, Eric evolves from a solitary figure chasing personal and national glory into a key team player. His early arrogance diminishes as he gains respect for his teammates' diverse backgrounds and abilities, particularly recognizing Hikaru's leadership and dedication. This journey traces his arc from isolation and pride towards integration and mutual respect within a collective sporting environment.
