Seto was a blue-white blur on KaibaCorps’ brand new racetrack. From the safety of the sidelines, Mokuba kept one eye on the camera mounted to his brother's helmet and another on the control center on the parameters for the hologram technology they'd installed along the track.
Seto drew a card from the duel disk mounted on his custom-made Blue Eyes White Cycle. He summoned a monster with a flourish. Mokuba saw his mouth move, calling out the creature's name, but the sound was lost amidst the roar of the motorcycle's engine. The hologram's control center beeped and hummed. Mokuba watched its usage metrics climb as the graphics engines that lined the race track did their damndest to bring Seto's monster to life.
Seto had come up with the idea after investing in Formula One. After a week at the races, he'd come home to Domino City and described his vision to Mokuba over parfaits: a new kind of duelling, where the adrenaline rush of a race could combine with the cerebral thrill of a successful duelling strategy. He wanted to create a duel disk that could interface with a vehicle and incorporate its speed and position into the outcome of a duel.
When he'd pitched the idea to their board, Seto had made it sound like his motives were financial: an untapped market, a new line of products that could take advantage of their recent partnerships with transportation manufacturers. But Mokuba had seen the passion in his eyes, as their parfaits gleamed in the afternoon sun. He hadn't seen his brother so excited since Yugi Motou's pharaoh had left the mortal plane. What kind of brother would he be if he didn’t do everything possible to keep that spark in his brother’s eyes?
Mokuba had spent half a week without sleep trying to create hardware that could make Seto’s dream a reality. For now, all he had to show for his efforts were a series of defunct duel disks, unable to handle the strain of running holograms and interfacing with the motorcycle.
Just as it had in their previous trials, the duel disk's central processing unit began to overheat.
Mokuba swore. His fingers flew over the control center's console, issuing a series of subcommands to mitigate the damage. As a result the duel disk only emitted a puff of smoke when it gave up the ghost, instead of exploding like it had the last dozen times.Mokuba sighed and switched off the holograms.
Seto came to a stop and dismounted his motorcyle. He removed his Blue Eyes helmet, shaking his hair out of his eyes."That was better," he said. The tone of his voice was serious, but Mokuba could see the glimmer in his eyes, the slight curl at the edge of his mouth. After years of quiet despondency, his brother was finally happy again.
