Description
Quentin Cinquedea, known in Japanese as Sengūji Yamato, is a character in the Inazuma Eleven GO anime. He is a teenage boy with blue eyes and pink hair cut to shoulder length. His English name follows the naming pattern of the Dragon Link team: Quentin derives from the Latin quintus, meaning fifth, and Cinquedea is an Italian term meaning five fingers, both references to the Fifth Sector organization with which his team is connected.

Quentin is the son of Gyan Cinquedea, the founder of the Fifth Sector and the coach of Dragon Link, and he closely resembles his father. He serves as the goalkeeper and captain of Dragon Link, an elite team privately assembled by Gyan whose starting eleven consists entirely of keshin users and which presents itself as the ultimate team of the Holy Road tournament. In the tournament final, Dragon Link made an unprecedented move by replacing all of Seidouzan's players at halftime. Under Quentin's leadership, the team gradually cornered the Raimon side before ultimately losing to Raimon's refusal to give up.

Quentin is described as a charismatic leader of his team. As captain, he directs his teammates with assurance, and as the son of the Fifth Sector's founder, he initially stands with the organization's controlled style of soccer. His role in the story is that of a principal opponent during the Holy Road arc, serving as the final barrier between Raimon and the title.

His development continues in Inazuma Eleven GO: Galaxy, where he is recruited by Caleb to join the Resistance of Japan and serves as that team's goalkeeper. The move places him in opposition to the Fifth Sector and aligns him with the side working to restore free soccer, marking a clear shift from his earlier position. His key relationships include his father Gyan, whose team he captains and whom he greatly resembles, and Caleb, who brings him into the Resistance.

As a player, Quentin is the goalkeeper of a starting lineup in which every member is a keshin user, making him part of a team built around the avatar powers central to soccer at the time. His defining traits are his composed captaincy, his family tie to the Fifth Sector, and his eventual turn toward the Resistance.
