On the large field of clay, Hayate stood next to all six of his Pokemon, looking at a notebook he have on his hand.

"Well, seems good now. Just small adjustments. Noivern, try Boomburst on the 100m target over there again."

He closed the book with his hand and looked over at the Dragon Pokemon. It walked over a little bit, and a sonic wave started to appear on its large, boombox shaped ears. A second later, the target 100 meters away shattered.

"Aah..." Allister shook his head, feeling the wind die down around him, and the chill air slowly return to a pleasant lukewarm temperature. The young gym leader, aware of what just happened, slowly turned to look at his team, all of which had calmed down by now, and all of which were staring back at him. "W-wonderful, g-great work everyone," He spoke in that gentle, yet melodic voice that they loved, as all of them spun around in joy. "H-however... Nd I say this w-with love. Empress, time shadow ball correctly next time. Dreamer, you *Knew* Magician is faster th-than Star, I taught you trick room for a reason. Star, you're m-missing a lot, please stop." 
Aah, there it was. While their trainer was loving, and went out of his way for them, he was also a boy with high expectations. They all nodded, before returning to him, but Star lingered behind. "...Hmm." Allister frowned, before walking over to sit next to his cursola. "Star?"
*"..."*
"'M not mad at you, y'know that?"
*"...Mr. Allister I-"*
"AGH!" Allister shrieked when a blast came flying out of nowhere, smacking the cursola, and sending him halfway across the arena. The boomburst must have hit him on accident. "Wh... OI!" Allister turned to look at Hayate's Noivern, who used the attack. "C-could you..." He slowly realized that this pokemon had a trainer, and started to back away. "Could you not?"
Joe
"Uh oh." Hayate did not see that there was... A child? Next to the target. Obviously, with Allister's soft voice, a hundred meters away is going to make him absolutely unheard. Regardless, Hayate climbed onto Noivern and flew over next to the kid, with the rest of the team following. With the Pokemon's exceptional speed, they covered the length in just three seconds, causing a huge gust of wind when they landed next to the boy.
"Are you alright?" Hayate jogged over to see if the trainer was hurt. "I'm sorry that hit you. We did not notice you... Are Allister!"
At first glance Hayate could not recognize the trainer, but once he saw the white mask, he immediately remembered the famous ghost type expert.
Samuel
"..." Oh dear, what did this guy want. Allister, unbeknownst to Hayate, turned red upon being recognized, and slowly backed away. "I-I..." He sort of froze, as he one, felt bad for yelling at this guy while paradoxically being mad at him for hitting Star, and two, was really *Bad* At interacting with fans... Was this guy a fan? "Y... Y-yes, tha's me," He eventually managed, nodding his tiny head a bit. "Need somethin'?" From the looks of this young man, he was a competent trainer, but Allister couldn't tell if he was a gym leader, champion, elite four, or what.
He reactively took another step back, wishing that something would just interrupt them already. Lucky him! Something did, when Star's voiced sounded in the background, calling, *"I'm out!"*
Allister turned to see the ghost type, having retreated into its shell, was now rolling off, and without him no less! "'M s-sorry for bothering you," The boy quickly said. "B-but my cursola's n-now rolling away... S-so... If you need anything, make it quick!"
Joe
"Um, I can help, I suppose, for causing the trouble." Hayate gave a look to his Staraptor, and the Eagle Pokemon flew up in the air, and swooped the Cursola up with his strong talon claws, then returned the trainers steadily, placing down the Pokemon gently. 
"Thanks." Hayate fixed his hat and looked back at Allister. "We haven't met, haven't we? I'm Hayate, Gym Leader of the Flying Type Gym in the Minor League of Galar. So technically, we are coworkers. And this is my first team here."
