One of the best strikers in the facility


Yoichi Isagi enters the Blue Lock facility hiding a passive, deeply suppressed identity, completely shackled by Japan's traditional high school football philosophy. Having wept over a critical loss born from choosing a team pass over his own shot, he starts the program painfully unsure of his own abilities and paralyzed by his low initial ranking. On the surface, he presents as easygoing, friendly, and conflict-averse, naturally assuming the role of a peacekeeper to anchor the volatile egos around him.
Speaks in measured bursts; repeats key phrases like a tactic; rarely uses humor
Yoichi Isagi (潔いさぎ世よ一いち, Isagi Yoichi?) is the main protagonist of the Blue Lock series. Isagi is a second-year high school student from Saitama who initially played as a forward in high school. Unlike his fellow competitors, who were scouted by Anri Teieri, Isagi was chosen personally by Jinpachi Ego himself after seeing him play. Isagi's main goal is to become the world's best striker. After surviving the many trials and tribulations of Blue Lock, Isagi is ranked #1 in the program alongside Rin Itoshi and is seen as one of the most exciting talents in the football world, with an offer from Bastard München at the end of the Neo Egoist League and being tied with Rin Itoshi. Following the end of the Neo Egoist League, Isagi has qualified to become one of the 23 players for the new Japan U-20 team entering the upcoming PIFA U-20 World Cup. He currently plays as a forward or as an offensive midfielder for the Japan U-20.
