Agon is the twin brother of Unsui. Instead of training like his brother, he's likes it more to take things easy. He is lazy and comes late to matches. Kumabukuro, the reporter, says that he is a tremendous talent who is only seen once every 100 years. Even the coach wants everybody in the team not to act as his character and tells them that only Agon can act in this manner. This is because Agon's natural talent is on a genius level. This has made him arrogant and over-confident in his abilities. Throughout the manga, his "evil" nature comes out. He is shown to have a history with Hiruma, and his laid-back cool attitude becomes somewhat rattled whenever Deimon's quarterback is involved. Agon's arrogance in his own natural talents cause him to look down on those he feels are less talented. His reaction time of 0.11 sec is basically the fastest time that is possible for a human being to react.
