Yoichi Isagi's Personality
Yoichi Isagi is a passionate, determined, and confident egoist who strives to become the best striker in the world. He is also a team player, a leader, and a visionary who can inspire others with his goals and actions.
Isagi’s personality was initially shaped by his admiration for Noel Noa, a legendary soccer player who was known as the “Hero of Japan”. Isagi wanted to be like Noel and play soccer with joy and courage. He also had a strong sense of justice and fairness, as he would stand up for his friends and teammates against bullies and injustice.
However, Isagi’s personality changed drastically when he joined the Blue Lock project, a facility that aimed to create the ultimate egoist striker by eliminating all other players. There, he was forced to abandon his team-oriented mindset and focus on scoring goals by himself. He also had to face his own weaknesses and fears, such as his lack of talent, his hesitation, and his self-doubt.
Through the harsh and intense training and matches at Blue Lock, Isagi developed a new personality that was more egoistic, aggressive, and competitive. He learned to trust his instincts, to take risks, and to challenge himself and others. He also discovered his own style of playing, which involved using his spatial awareness, his reflexes, and his metavision to create opportunities and score goals.
Isagi’s personality also evolved as he interacted with other players at Blue Lock, who had different personalities, skills, and goals. He formed bonds and rivalries with some of them, such as Rin Itoshi, Nagi Chigiri, Shidou Hyoudou, and Reo Mikage. He also learned from them, as he adopted some of their traits and techniques, such as Itoshi’s charisma, Chigiri’s creativity, Hyoudou’s speed, and Mikage’s precision.
Isagi’s personality reached its peak when he faced the Japan U-20 team, the national team that represented the conventional and orthodox way of playing soccer. He proved his worth as the ace of the Blue Lock team, as he scored the winning goal and led his team to victory. He also declared his ambition to win the U-20 World Cup, not as a hero, but as an egoist.
Isagi’s personality is not static, but dynamic and adaptable. He is always looking for new challenges and ways to improve himself and his skills. He is not afraid to change and grow, as he believes that is the only way to achieve his dream. He is also open to learning from others, as he respects and acknowledges their strengths and contributions.
Isagi’s personality is not perfect, but flawed and human. He has his own doubts, fears, and regrets, as he sometimes questions his choices and actions. He also has his own emotions, such as anger, sadness, and joy, as he reacts to different situations and events. He is not a machine, but a person who has a heart and a soul.
Isagi’s personality is not selfish, but altruistic and inspirational. He is not only playing for himself, but for his teammates, his friends, and his fans. He is not only seeking his own glory, but the glory of soccer and Japan. He is not only a striker, but a leader and a visionary who can change the world with his goals.
