- Vertical Jump - Kuon has an amazing vertical jumping ability which is 68 cm
Isagi had a great amount of respect Kuon due to his insane jumping ability and overall endurance. Kuon was also the first person to look out for Isagi, which he appreciated. Despite his betrayal, Isagi did not feel any resentment for Kuon, as he still went out of his way to talk to Kuon even after the entire team was giving him the silent treatment. In the end, it was Isagi who caused Kuon to tackle Seishiro Nagi since Isagi made Kuon realize that Team Z could have a fighting chance at surviving Blue Lock. Right now, Isagi and Kuon seem to be on good terms.
Raichi and Kuon had a pretty neutral relationship. Kuon looked out for all of his team members, including Raichi, and he was usually the person who would calm Raichi down whenever he got heated. After learning about his betrayal, Raichi quickly fostered a great amount of hostility towards Kuon. This hostility eventually dissipated once Kuon regained the team's trust by tackling Seishiro Nagi and getting a red card so that Team Z would have extra time to score the winning goal. Right now, Kuon and Raichi seem to be on good terms.
