Who Let Him Play Yu-Gi-Oh! novel Chapter 517

Chapter 517: Chapter 517: Energy Collection

KaibaCorp Headquarters.

"The energy storage unit is functioning properly."

Mokuba standing at the control console handed Kira’s Duel Disk back to him.

He had just performed routine inspection and maintenance on Kira’s Duel Disk, and adjusted and installed several new components.

Half a month ago, Kira had come specifically for a certain special component—the energy storage unit just mentioned.

It wasn’t a common device, but the technology wasn’t exactly rare. Its operating principle resembled the Bio-Band Professor Thelonious Viper forced all the students and staff at Duel Academy to wear in the early part of the anime’s Other Dimension arc.

In the show, the professor required everyone to wear his issued wrist device, which later turned out to be part of his scheme. Once worn, it couldn’t be removed. Every time a person dueled, the device would absorb the energy produced by the duel, siphoning off the duelist’s life force as well.

The endpoint of that energy extraction was in the secret lab the professor had built on the island. All the energy from the entire academy’s duels would be absorbed into the body of a Duel Spirit stored in that device.

That spirit was Yubel.

At that time, Yubel had returned from the stars through great hardship, grievously weakened—her power was a mere fraction of what it once was, and she couldn’t even manifest a physical form. So she manipulated Professor Thelonious Viper mentally and used him to collect energy to fully revive herself.

Inspired by Yubel’s method, Kira looked on the dark web and checked with Mokuba for devices with similar functionality. He actually found one.

"Incredible," Mokuba said in surprise after testing the energy storage unit mounted on Kira’s Duel Disk. "In just half a month you’ve collected this much energy... What kind of intense dueling have you been doing?"

"Haha, not that bad. Maybe the duels were just high quality," Kira chuckled.

Still, he had indeed been dueling frequently—active in the Spirit World every night, and fighting the Shadow Riders in reality. Most of those were dark duels.

A single dark duel generates many times the energy of a normal duel, and since he’d had a lot of matches, the energy piled up quickly.

"I’ve logged all the data, and the Duel Disk tuning is about done—did some maintenance while I was at it," Mokuba said with a grin. "It should be as good as new now."

"Thanks."

Kira took the Duel Disk back and strapped it on.

"Haha, no problem. I should be thanking you," Mokuba replied. "The product is still in testing. What you’ve gathered is invaluable test data—it’ll help a lot with future development."

He paused, then asked curiously, "But why the sudden interest in collecting duel energy? What do you need so much for?"

"Well..."

Kira smiled mysteriously. "Once I’m done, you’ll know."

He was collecting energy for the Sacred Beasts.

As mentioned before, the seven keys sealing the Sacred Beasts were a smokescreen. The real way to break their seal was through dueling. In the original story, it was the students’ dark duels with the Shadow Riders on Academy Island that awakened the three Beasts.

In theory, if you collected enough duel energy and poured it all at once into the Sacred Beasts’ sealing array, you should be able to break the seal as well.

When that time came, even if he couldn’t find Kagemaru, as long as he got to the Sacred Beasts before that old fox, the geezer would be left staring, slack-jawed.

"By the way, how are those victims doing?" Kira asked casually.

Mokuba blinked, then understood. "Oh, them."
