Yusei was taken aback and looked at "Godwin" in surprise, not expecting him to ask that so suddenly.
"Back then, Doctor Fudo developed the 'Perpetual Motion Machine,'" Kira said slowly. "Its key lay in a mediator particle called 'Stardust Particles.'
Doctor Fudo discovered that this particle possessed a highly unusual property: it could combine with all other fundamental particles and serve as an intermediary between any particles.
Later, he named his own son after this particle."
Kira gave Yusei another meaningful look.
"Do you understand what he meant?"
Yusei's heart jolted. "Stardust Particles... Yusei..."
Yusei himself was a tech nerd. He had once built a Perpetual Motion Machine by hand out of scavenged junk, so he naturally knew quite a bit about its basic principles. Of course, he knew Stardust Particles existed, and he had considered whether there was some coincidence behind his name matching that particle.
It was simply that no one had ever pointed it out to his face before, so he had been unable to think too deeply about it.
But now...
"Yes, I think you understand," Kira said. "Your father hoped that you would become a person like Stardust Particles.
Someone who could forge connections between people, let anyone understand one another, and become companions. In other words, what you call 'bonds.'
With the bonds between people, that power could transcend everything and bring hope."
That was also the central theme of Yu-Gi-Oh! 5DS, and the primary way Yusei kept powering up and growing stronger throughout the story.
To put it in more fantasy-like terms, "bonds" were the "path" Yusei walked. The power of companions and trust allowed him to break through his limits time and again, repeatedly pull off God Draws and print miracle cards, even shattering Z-ONE's understanding and creating a brand-new future that
