UK:GSW Chapter 151: Testing the Game—Uchiha Kei’s Twisted Sense of Fun 

"Ultimate Storm."

To most people in the Shinobi World, this name meant nothing. They couldn't help but wonder what kind of game it was—especially since there were only so many genjutsu-based games out there.

But on Earth, this title was far from obscure. Anyone familiar with console or PC games had likely heard of it. And for fans of Naruto, it was practically legendary.

This was none other than the most globally popular Naruto spin-off game series: *Naruto Shippuden: Ultimate Ninja Storm*—a game so well-received it was praised for surpassing the anime in its storytelling and visuals. By the time Uchiha Kei had transmigrated, it was already on its fourth installment.

Naturally, the first fighting game Uchiha Kei developed in the Shinobi World was inspired by this masterpiece.

Of course, he made extensive localization changes for the ninja world and avoided using canon characters for obvious reasons.

The initial roster consisted of twelve unique characters. Each had their own style. While most used the standard kunai, some wielded other weapons—longswords, spears, massive blades, dual blades, and so on. Before battle, players could also choose a support item like exploding tags or shuriken—but only one type per match and in limited quantity.

The twelve fighters came with their own names and backstories. To keep things balanced, they represented the Five Great Nations, two characters per village. The remaining two were rogue shinobi unaffiliated with any village.

That was it for now—after all, this was only the first installment of "Ultimate Storm." Future sequels—Storm 2, 3, 4, 5—could be added later, turning it into a full-fledged series like *The King of Fighters*, *Tekken*, or *Street Fighter*.

Uchiha Kei also implemented a "Free Mode," which allowed players to scan themselves and enter the game. The scanned version wasn't a perfect replica—it was adjusted using the game's built-in balancing system.

Free Mode capped all players at standard Jōnin-level stats. Each player's attributes were automatically calibrated based on their real abilities. For example, someone good at genjutsu would have higher illusion stats, while a taijutsu user would see boosts in the physical category. The total stat pool was fixed at 100 points, distributed accordingly.

In short, the balance system ensured players didn't have to change how they fought. Whether buffed or nerfed, their combat style remained true to reality.

Sure, this might limit the game's potential as a combat training tool, but hey—it was just a game. If someone wanted to use it for a military arms race... well, good luck with that.

As far as Uchiha Kei was concerned, the system balanced things however he wanted. If the Hidden Leaf needed a special version, he could just unlock an unrestricted build and let Konoha shinobi go wild inside.

As for the other villages?

Please. They weren't allies. Why should he empower them? If they wanted to use this game to train their ninja, they could buy the regular version.

And if they came begging for the original, uncut build? Sure—he'd whip up an export version. As a transmigrator, Uchiha Kei had no shortage of tricks and zero guilt about exploiting people commercially.

That was the game. And once the four little brats entered, Uchiha Kei—using his GM perspective—gave them a quick rundown, then let them choose their characters.

Free Mode wasn't the focus right now. The goal was to test the performance of the game's original characters.

The four had experience roleplaying others in games. Uchiha Kei's earlier genjutsu-based title, "Homecoming," had them embody a thirteen-year-old boy who tragically died in the war. This time, there were just more options.

Naturally, as Hidden Leaf shinobi, they instinctively went for Konoha characters first.

It came down to speed. In this test version, duplicate character selection wasn't allowed—whoever picked a character first got them.

In the end, Kakashi grabbed one of the two Leaf fighters. The character's name was Sayun—a white-clad, silver-haired swordsman wielding a tachi. Kakashi chose him simply because he resembled his father, Sakumo Hatake.

To that, Uchiha Kei responded: resemblance? That character was basically a modified version of the White Fang. Even Sayun's name was one of the many translations of "Sakumo."

After being filtered through Japanese → Chinese → Japanese again and localized for the ninja world, it ended up sounding similar—but was written entirely differently.

For a moment, Kakashi truly felt like he'd seen his father again.

Then it was Obito's turn. He took the other Leaf character—a blond, speed-focused ninja wielding an elongated kunai. The character used a super version of the Body Flicker Technique and specialized in sneak attacks from behind. His name was Kaino.

Obito picked him because he reminded him of his teacher, Minato Namikaze.

No surprise there—Kaino was absolutely modeled on Minato. Just like Sayun, his name had gone through a chain of translations and localization. The resemblance was clear to anyone, but the name was technically distinct. Most would just think Uchiha Kei had drawn inspiration from his buddy Minato while designing him.

As for Might Guy and Shisui Uchiha—they were slower to act. Since Konoha didn't have a taijutsu specialist among the original twelve, Might Guy ended up selecting a character from the Hidden Cloud Village.

Given the Cloud's reputation in hand-to-hand combat, it wasn't a strange choice. The character was a stereotypical dark-skinned muscleman named Black Mamba. He had a special elbow strike and a voice line that inexplicably shouted "Hey-man!" during attacks.

Last was Shisui. After a quick glance, he chose one of the two rogue nin—a female genjutsu specialist. Since Shisui had always been fascinated by illusions, the choice made sense.

For a five-year-old boy, gender-swapping wasn't an issue. He was just curious and excited to try something new.

Once all four had locked in their characters, their surroundings shifted. In the blink of an eye, they found themselves in a massive arena—the size of a world-class football stadium.

This was their battlefield.
