• Yoichi Isagi

Yoichi Isagi (潔いさぎ世よ一いち, Isagi Yoichi?).

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.

• Appearance:

Isagi is a teenager of slightly above average height and slim build, developing a stronger, more defined-looking physique. He has short, blue-black hair that leaves a V-shaped fringe between his deep blue eyes (he believes it brings him good luck), along with a plant shaped ahoge at the top of his head.

While attending Ichinan High School, he wore an unbuttoned blazer over a white undershirt and striped tie. Both the Ichinan High jersey and gym uniform are light-colored with black stripes.

At Blue Lock, Isagi wears the standard-issued body suit (black with blue stripes) and tracksuit. During the First Selection, he wore Team Z's blue #11 jersey and Team Z's gray-capped cleats. During Second Selection, he wore Team White's #15 jersey and later switched to red. He then later switched to Team A's black #15 jersey during the Blue Lock Eleven tryouts.

• Personality:

Isagi is easygoing and has a generally friendly, cheery personality, but his simple and innocent habits often get on the nerves of the people around him. He tends to avoid any childish squabbles among other Blue Lock competitors and tries to be a peacekeeper between his friends and rivals. At the beginning of Blue Lock, Isagi is massively unsure of himself and his skill due to being the second-lowest-ranked player in Blue Lock initially and his conflicting ideas of football. As time goes on, Isagi develops a more assertive presence on and off the field, becoming the foundation for Team Z and garnering the respect of some of the best players in Blue Lock, who mostly have heavily assertive or dominant personalities. As of Third Selection, Isagi has the confidence, charisma, and reputation to talk openly with Rin Itoshi, one of the most talented yet difficult people in the Blue Lock Project.

Initially, Isagi was unsure on how to proceed in Blue Lock due to being taught an ideology during his time in high school that conflicted with what was being promoted in Blue Lock, as well as being unsure on how to be egotistic. However, starting with Team Z's first win and subsequent wins thereafter, Isagi becomes well-acquainted with the rush of victory and the cold ruthlessness needed to survive in Blue Lock. As times goes on, he becomes willing to step on the plans and dreams of his opponents and teammates in order to score a goal and go further in Blue Lock. When it comes to football, he is ambitious and calculated, willing to change and adapt, to get the right "chemical reactions" out of his teammates, to stay a step ahead of their opponents, and be the best player on the field, staying true to his commitment to becoming the world's best striker. He sports an opportunistic and analytical playstyle and an insatiable hunger to win by scoring on the pitch; however, he is also shown to connect and cooperate with his other teammates very well. Importantly, Isagi has often valued and recognized the strengths of others' play, but as he proceeds through Blue Lock, he is able to identify and harness his own strengths to score.

Ever since meeting and losing to Rin, Isagi has been chasing him, attempting to surpass him at every turn. He goes out of his way to get closer to Rin, attempting to copy his cooldown routines and adapting his mindset in an attempt to get closer to his level. Isagi believes that when he is able to truly surpass Rin, he will be closer than ever to his goal of becoming the best striker in the world. Isagi is still prone to being nervous before big matches, such as the end of the First Selection, the beginning of the Third Selection, or the Japan U-20 match, and was slightly nervous while being interviewed after his decisive goal. However, in each case, Isagi was able to fully realize his ego and confidently stake his place among the best in Blue Lock, declaring that he would lead the Japan U-20 to victory in the World Cup. Isagi now doesn't like it when someone believes that his successes are just out of luck and not because of his skills as a striker. When he meets Tada, an old teammate from his school, and comments how "lucky" he was to score that goal in the match against Japan U-20, Isagi feels dismayed since Tada had absolutely no idea how much he had to fight every day inside of Blue Lock to get in the position he is currently, yet it does not dismay him for long as it motivates him into returning to Blue Lock and evolving even more.

After the beginning of the Neo Egoist League, Isagi's ego is much more noticeable than before, feeling completely insulted when Yukimiya questioned his decision to make a pass, calling him someone with a small mindset. The conversation enraged Isagi and provoked him to the point of almost getting into a fight with Yukimiya inside the dressing room. He is also entirely capable of showing frustration when things don't go as he planned; in the Bastard München vs. Manshine City match, he is frustrated and enraged when Kunigami took advantage of his misfired shot due to Kaiser, and even more when Kaiser makes fun of him, saying that he prefers making passes to goal instead of scoring goals himself, no longer caring about showing his egoism. According to Noel Noa, Isagi has an almost identical perspective on football as Ego, as they both share a mutual obsessive desire to win; he has even begun to exhibit a similar devilish smile on his face like Ego's whenever he's pumped up.

In the final match against Paris X Gen, after learning that Noa had been using him as a stepping stone for Kaiser from the very beginning, Isagi discovered an unfamiliar level of rage and frustration within himself. Furthermore, understanding that if he lost, everything he had done up to that point would have been in vain and he would be consumed and forgotten by the geniuses of football, Isagi unveiled a new ego, which relied on him "selling his soul for the sake of winning." He no longer cared about being the star or even being able to surpass "geniuses" in soccer; all that mattered to him was winning at any cost. This earned him the respect of world-class strikers like his former idol, Noel Noa, who began to see him as a genuine threat and accepted Isagi's grand public challenge to best him in the upcoming PIFA World Cup.

At the end of the match, with Isagi scoring the winning goal, Rin Itoshi recognized Isagi as the "Neo Egoist." He continued to evolve and adapt continuously, awakening the egos of others and using them to achieve their own goals, acknowledging him as the "Demon King of Blue Lock." From this new development, Isagi started to embrace Noel Noa's philosophy of being a "football junkie," as he aimed to improve by inspiring and then defeating strong rivals, evident in the first U-20 World Cup game against Nigeria.

During his match against France, Isagi felt he was under immense, multi-layered pressure stemming from being recognized as the "heart" of the team while facing world-class opponents who were actively dismantling his playstyle. The pressure was not just physical but heavily psychological and strategic, forcing him to adapt or face complete downfall. According to Vivian Hugo, Isagi's inability to handle the pressure he faces is why he is more suited to being the best midfielder instead of the best striker. He believes he has the potential to rival him and guide Japan to victory if he were to accept his "destiny" as "Number 2." Ultimately, in the final minutes of the match, Isagi discovered his "true destiny" not as "Number 2" or "Number 1," but as a rebel who devours "Number 1" to achieve victory.

• (To himself) "Football is a sport played with 11 people. So, one person can't win on their own. Football isn't just for one. One for all. I wanted to win!"

• (To himself) "I didn't come to trample on others to become the best in the world!! I came here, so, I need to defeat those who are stronger than me! Or else, nothing will change!!"

• (To himself) "Inside of me? I wanna know more! What my monster really is. That could be my one clue to surviving inside Blue Lock".
