With the recent clips for the show, we’re allowed to see Yusaku’s active expressions and dialogue. Already, everyone is seeing the same thing.
THE BOY DOES NOT CARE!
Yusaku seems to display indifference and a complete lack of interest in regards to dueling. (Kinda refreshing to see a calm and mature character when all we’ve ever seemed to be getting since 5D’s was hyperactive, dueling enthusiasts.)
However, it is implied that Yusaku once had the same enjoyment and fun with dueling as all the other protagonists. Shoichi stated “If that didn’t happen, you’d probably be able to still have fun with dueling.”
This implies that Yusaku used to be like everyone else and enjoyed it. But this also asks the question of what exactly Shoichi is referring to. Does he mean that something happened that might have put off (or traumatized) Yusaku or does he just mean that Yusaku can’t be as fun or carefree as he once was? Whichever, it implies that something happened in the past that involved a negative experience with the game.
So, we’ve seen that Yusaku does not like dueling; which, considering how big a part of life it probably is in-universe, is something that anybody with an intact brainstem is probably connected to, whether by doing it or watching it.
When the show first popped up, the theme was “Let’s take one step forward and try it!”
Everyone at the time was thinking that it was a reference to making friends and trying new things, even if we’re scared. But what if it means something different.
What if it’s referring to Yusaku’s reluctance to duel?
What if Yusaku is so caught up in what turned him off of dueling, that he isn’t even trying to enjoy it anymore? It’s possible that Yusaku is so against dueling, that he’s not taking the time to play or have fun.
Maybe the theme is referring to Yusaku attempting to take the initiative to enjoy the game again and maybe the other duelists like GO and Blue Angel will help him to make a show out of dueling and to find happiness in it again.
A part of me hopes that it will make use of the idea of an audience, maybe having moments where the audience attempts to encourage or rev up Playmaker while he’s dueling or having some hardcore fans of his (Naoki) going on about how serious he looks at first and then, as the show progresses, showing how happy he has begun to look while he duels.
