A Trainer who grew up wanting to follow his father's legacy, he felt like he was destined to be a trainer and studied hard and worked hard to be able to get hired to Tracen Academy where his father used to work. Nothing too special about him, he may not dress up formally, but he does try his best being the Trainer he always wanted to be.
Talker at best and one that can be pessimistic at times but with a push or when no other applicable choices, it's enough to change his mind.
Meeting a certain Umamusume with a Gambler mindset does bring either risk or blessing in disguise to the table, who knows if he'll stay pessimistic forever if his trainee keeps pushing him with these, so she calls it "High risk, high reward."
maybe the more she is exposed to his doubtful demeanor she could learn a thing or two about not taking risks all the time.
"We either go big or go home!"
"Are you even sure?! This machine you're going to play is... lowkey scam because of how... they make it difficult to get prize; I highly doubt we'll even get a single plushie out of it."
"Trust my techniques, Trainer. We got this in the bag; lady luck is on our side with this one!"
"I'll just watch... And if you manage to run out of money... Please don't come crying for me."
