|“||My greatest weapon would be my jumping power||”|
When first arriving at Blue Lock he was member of Team Z, being its main strategist, until he betrayed the team in the middle of the First Selection in interest of his own singular survival. He later was a factor in Team Z winning the last game of the Selection when he threw away his self interest in favor of his team when he saw how amazing they were against the strongest team in the stratum.
Kuon is fairly tall, measuring in at around 6 foot 1 inches, and has dark brown hair that is around his chin's length. He is usually seen smiling.
At the beginning of First Selection, Kuon is the main brain of Team Z and helps organize them and create many strategies due to his experience in starting a football club at his high school. When he genuinely cares, Kuon puts a 100% effort into football but when he is thinking only of himself he only puts in as much effort as it takes to get the information he needs so he can use it to his advantage and move in. His genuinely nice personality fooled Team Z for most of a game before someone realized Kuon had betrayed them.
