Jiro Usui is a supporting character who appears in the anime film Inazuma Eleven: Saikyō Gundan Ogre Shūrai. He is a member of the team Prominence, which is one of the rival squads encountered by the main characters. Usui is known for his arrogant and highly competitive personality, particularly regarding his own speed. He firmly believes that his acceleration and running pace are unmatched, a point of pride he frequently boasts about to others. This confidence often leads to friction, especially with his teammate Kosuke, as the two share a fierce rivalry over who is the faster player on the field.

In terms of background, Usui is a forward. Within the narrative of the film, Prominence serves as a formidable obstacle, and Usui’s role is to act as a speedy attacker who pressures the opposing defense. His motivations are largely driven by a desire to prove that his speed is superior to both his rivals and his own comrades. He is not a primary antagonist but rather a specialized opposing player designed to challenge the protagonists in a specific athletic skill.

Key relationships for Jiro Usui are primarily defined by his interactions with his fellow Prominence members. His most notable dynamic is with Kosuke, which is characterized by constant bickering and one-upmanship over who is faster. Despite this antagonistic relationship, both players work together as part of the team structure, suggesting a grudging respect buried under their verbal clashes.

Jiro Usui does not undergo significant character development or a personal arc within the film, remaining largely static as a representative of his team's overall tough and competitive nature. His notable abilities focus exclusively on speed. He utilizes the hissatsu technique "Flame Dance," a dribbling move that allows him to maneuver past defenders with a fiery burst of acceleration, directly complementing his self-proclaimed title as the fastest player on Prominence.
