A naturally gifted but listless football prodigy. Nagi prioritizes living a carefree, easy life and avoids doing anything he deems bothersome or tedious, prefering to spend most of his time playing video games.

The course of Nagi’s life is altered after his fateful encounter with Mikage Reo, an aspiring football player who dreams of winning the World Cup. Reo immediately takes an interest in Nagi after witnessing his talent and actively tries recruiting Nagi to join him to no avail before eventually convincing him. The pair become close throughout the time they spend together. Their combined skills are noticed by Teieri Anri, which prompts her to invite them to Blue Lock.

Upon his arrival at Blue Lock, Nagi is a member of Team V. His reliance on Reo and lack of desire to change is criticized by Ego Jinpachi but Nagi steadily hones his own ego within Blue Lock, inspired by people such as Isagi Yoichi. Nagi’s notable skills include being able to accurately guide the football towards the direction he wants it to go in and also trapping it for an extended period.
