"My name is Kurama. That's the name given to me by my father and creator, the Sage of Six Paths. But over the years, humans—those annoying creatures—have come to call me by another name: the Nine-Tails."
"I used to be a free Tailed Beast, a fox who chased freedom and beauty. Even though humans often harassed me, I got by. I never had much hatred for them or this world."
"But then, one day, that evil man named Madara Uchiha found me and used those cursed Sharingan eyes to forcibly control me."
"From that moment on, my nightmare began. That wicked Madara forced me to fight against the so-called God of Shinobi, Hashirama Senju. In the end, I was beaten brutally by that monstrous Hashirama alongside Madara."
"Hashirama may have freed me from Madara's control, but he said I was too dangerous and sealed me into Mito Uzumaki's body, turning me into a prisoner—just another Tailed Beast trapped inside a jinchūriki."
"The worst part? Mito Uzumaki was ridiculously powerful. Trapped inside her, I couldn't resist at all."
"After both Madara and Hashirama died, and Mito grew old and passed away, I thought the worst was behind me."
"Then came Kushina Uzumaki. Loud and annoying, but nowhere near Mito's level. I believed I could eventually find a chance to break free."
"I was waiting for that perfect opportunity."
"But then… just when I thought I was biding my time, Kushina brought her blond boyfriend and an annoying Uchiha into the seal space and said they wanted to negotiate with me."
"Negotiate? Who do they think I am? I'm the strongest Tailed Beast! My power can level the Hidden Leaf and the entire Land of Fire! Negotiate? I wanted to wipe them all out!"
"Even when they attacked me, I wasn't afraid! Even if I couldn't move and had to take their hits, I would never surrender!"
"I, Kurama, the Nine-Tails, will never yield!"
"That's what I thought."
"But then… I realized I was terribly wrong. That Uchiha kid—he may not be as strong as Madara, but his evilness? He far surpassed him!"
"That damned naturally evil Uchiha brat… he actually… he actually…"
"AAAAHHHHHHH\~\~\~\~!!"
In the seal space, Kurama let out a bone-chilling scream. Even with chains binding his mouth, the howl pierced from his very soul.
In his agony, Kurama exploded with terrifying power, even snapping a chain of Adamantine Sealing Chains. One of his massive claws broke free.
But Kurama didn't attack. He clutched his stomach, convulsing on the ground like he was having a seizure. His body trembled uncontrollably, and his mouth foamed—it looked really bad.
At that moment, Minato Namikaze and Kushina Uzumaki had no time to worry about Kurama. They were staring, wide-eyed and horrified, at Uchiha Kei.
Because Uchiha Kei had just calmly spoken the name of a skill.
Yes, the name was abstract beyond belief. But Kei had to say it aloud—because this system-issued skill required him to verbalize it to activate, and the target had to hear it for the effect to work.
Even if he wanted to cast it silently, he couldn't.
But Kei trusted in his bond with Minato and the others. Even if they heard it, he believed they wouldn't mock or ostracize him.
Yes… never underestimate the power of friendship!!
Minato swallowed hard and gave a strained smile. "Um, Kei… this… 'Colonic Taste Bud Technique'… that's just a metaphor, right?"
"..." Kei looked at him silently.
"It is… right?" Minato's smile froze.
"..." Still silent.
The only sound was Kurama's soul-wrenching scream.
"..." Minato fell silent too. Then, after glancing at the suffering Nine-Tails, he suddenly looked enlightened. With a serious face, he declared:
"I get it now, Kei. This is your resolve—your ideal."
"Whether it's a technique, skill, or jutsu… in the end, all that matters is whether it works. And your eye technique is undeniably the ultimate move. Even if it carries heavy moral burdens, its effectiveness can't be denied."
"Even my Wind Style: Rasenshuriken combined with your Fire Style: Great Dragon Fire Jutsu to create the ultimate Crimson Flash didn't make Kurama scream. But now? Your eye technique made him surrender completely. That's proof of your strength and resolve!"
Minato looked at Kei with newfound admiration. "You're incredible. You've done something I might never achieve in my entire life."
"..." Kei remained speechless, utterly dumbfounded. If he didn't know Minato well, he'd think the man was mocking him.
Also… that cringe name for the combined jutsu? Really? If I don't name my techniques, you'll just make stuff up like that?
Then Minato looked at Kurama, puzzled. "By the way, Kurama is a chakra being and hasn't eaten in ages. Shouldn't that 'Colonic Taste Bud Technique' be ineffective?"
Kei nodded. "In theory, yes. But his chakra is highly corrosive."
Kushina, who had been eavesdropping, looked over curiously.
Kei explained, "Kurama, being made of chakra, still simulates the anatomy of living creatures. Back when the Gold and Silver Brothers from the Hidden Cloud were swallowed by him, they ate his flesh in his stomach, which forced Kurama to spit them out."
"That proves he has internal organs—even if made of chakra, they're physically real."
"That means my Colonic Taste Bud Technique can be activated."
"Once triggered, the taste buds grow and directly sense the corrosive chakra surging through his intestines. And let me tell you—my taste buds are extremely sensitive. Plus, they're not native to his body, so there's rejection."
"Kurama is currently experiencing that entire intestinal tract packed with taste buds constantly tasting his corrosive chakra. Because of the sensitivity, the pain is multiplied—like Kushina getting hit by Kurama's chakra dozens of times over."
"And… I suspect it also feels like he's being force-fed super-spicy ghost peppers… through his intestines. Which are way more sensitive than the mouth."
"So now… do you still think it's strange he's screaming like that?"
Kushina and Minato quickly shook their heads, staring at Kei like he was a demon incarnate.
Even just hearing that made them feel phantom pain and overwhelming heat.
But Kei wasn't done.
"This technique still has flaws. It's ineffective against beings without intestines or waste in them."
"So I'm trying to improve it—make the enemy grow intestines even if they didn't have any, and generate waste even if they didn't eat."
"Eventually, I want them to experience tasting that waste with those same taste buds."
"Maybe even evolve it further—make eyeballs and nasal tissue grow inside the intestines. Total sensory overload."
Hearing that, Minato and Kushina's pupils shook violently. Kushina grabbed Minato and shivered, while he broke into a cold sweat, clearly wanting to beg Kei to stop.
But before Minato could even open his mouth—
Kurama spoke.
"I surrender! I surrender! I'm done! I won't fight! I give up!"
His voice and eyes were filled with absolute terror. He looked at Kei like he was the most terrifying devil. This fear ran deeper than what Madara ever gave him.
What the hell happened to this world? How could something like this be born here!?
A 'Colonic Taste Bud Technique' was bad enough. But now this monster wants to force intestines into beings that don't have them!? And grow waste inside!? Even turn intestines into sensory hellscapes!?
Even if it's technically survivable, Kurama felt his dignity as a Tailed Beast would be utterly annihilated. Better to be a pet—or even die—than face that.
Compared to that, staying sealed inside Kushina and supplying chakra for decades suddenly didn't seem so bad.
At least this nightmare would eventually die of old age. Just a few decades—Kurama could survive that.
Minato and Kushina were stunned. They never imagined the Nine-Tails would surrender… like this.
Sure, Kei's skill was utterly demonic and terrifying. But for the Nine-Tails to give up with logic and self-preservation? That flipped their understanding.
Only Kei smirked in secret. He knew his psychological warfare had worked.
Because all those horrifying upgrades? Total nonsense. He couldn't even modify the skill—it was a gold-tier ability from the system.
As if he'd ever draw some upgrade item for such an absurd technique!
