Kiro didn't need another authoritative position within the school, but the coach wasn't asking for his opinion on the matter, they were better than the rest. Their job, as per Coach Smith, was to help everyone who wasn't.
He was one person, whom couldn't tend to everyone that was there. So the help was very much welcome to him.
"We need to win this cup, we can't lose to those beneath us." He shouted as if preparing them for a war.
"What makes them beneath us..." Kiro mumbled as he was helping Nikolai. His cheeky comment earned him a laughter from his friend but a frown from the coach.
"What did you say smart mouth?"
"Nothing Coach." He gave him an innocent smile.
Though Coach Smith didn't buy it, so he walked up to him. "Don't just help your friends, the entire team needs you. Go help that kid." He said pointing to Ursa.
