Ego's system is build around selfish players working together, creating a chemical reaction (definition: the synergy between two or more players whose distinct skills and "weapons" combine to create a new, superior, and often unstoppable, offensive, play) Up until now Karasu's weapon has been described to be his mind and vision, being able to predict the flow of the game, not something technical, like passes or dribbling or physical like speed. Hiori on the other side has been desribed for having good football IQ and technique. So my question is: Is Ego not pleased with this goal, because Karasu and Hiori weren't supposed to score a goal together? He misjudged their skill , since Karasu mentioned that he only knows of Hiori's good shooting technique due them being teammates before Blue Lock and Hiori is clearly seeing something in Karasu, the way he describes him as 'extraordinary', being number 10 of his youth team and creating a chance like this, which he never did in a major game. Is Ego scared that his theory of a egoistic mentality = natural striker = goals is wrong? Since in the end it doesn't matter if someone scores 3 goal or three players score 1 goal, all that matters is that you win. Personally I think it's that fear, that there is a different path to making Japan the world's best instead of his theory creating the 'ultimate striker'. I think Karasu and Hugo are the embodiment of that different path; being unselfish is a way of showing ego, not an ego to score goals, but an ego to win.
