As for why the capture of Gyuki failed.

The answer is obvious.

After Sasuke used Amaterasu to burn Killer Bee in his tailed beast state, Killer Bee transferred his real body into one of his octopus tentacles.

At that time, he used the tentacle containing his real body to attack Sasuke and the others. A shame he only barely missed Karin. Killer Bee originally planned to dive into the water by slapping the surface, but who would have thought Sasuke would cut the tentacle off to save Karin.

And then this happened? Killer Bee just kept pretending to be the tentacle and silently sank to the bottom of the sea.

"A good chance, to get away from my bastard brother~ Yo, baby~."

"Stop with your annoying rapping already, Bee. You got several of my legs cut off."

"Ah well, don’t be mad, Gyuki~ Your legs will grow back, yo.~"

Gyuki was really fed up with Killer Bee’s rapping.

"If you leave the village like this, the Raikage will probably be furious, and he’ll probably pin the blame on that Sharingan brat."

"Ah, it’s fine. As a Jinchuriki, I’ve always been tied down by this village as a weapon. I need a break to rest now and then."

As the Raikage’s younger brother and the holder of the title ’Killer Bee’, he was strictly forbidden from leaving the village. Every day he had to train in the Cloud-Raving Valley. This wasn’t really the Raikage’s fault; even keeping Killer Bee in the village hadn’t stopped him from being tracked by the Akatsuki.

This time, if it had been almost any other member, Killer Bee might have died.

But Killer Bee couldn’t stand this kind of treatment; staying in the village all the time had been driving him crazy.

Now that he was free, Killer Bee didn’t care how worried the Raikage might be about him and just set off on his own journey. This trip out was the perfect chance to really work on his rapping skills.

In the Raikage’s office.

"What!? Bee was captured!?"

The table in front of the Raikage turned to splinters. Just like brothers. Even though they weren’t related by blood, their builds were very similar, both extremely burly, with the Raikage being even a size larger than Killer Bee.

It wasn’t hard to tell he was a strength-type ninja.

"You dare capture my brother, you Uchiha brat!"

"Darui, come with me to find that kid."

The Raikage called his most capable aide and was ready to set out immediately.

"Please calm down, Lord Raikage."

Mabui, standing beside the Raikage, hurriedly tried to soothe his temper.

"First Yugito, and now even Bee..."

This was already the second tailed beast Kumogakure had lost. Unlike other villages, Kumogakure’s two Jinchuriki were among the strongest of all the villages. Losing them meant not just losing the tailed beasts, but also two outstanding ninja.

"No, Bee wouldn’t be defeated by a kid like that. If it’s Bee, he’s definitely still alive."

"Mabui, how is the tracking going?"

"Not well. The tracking lizard stopped returning shortly after leaving the village."

After Sasuke separated from Hatake Karasuke, he returned to the Uchiha clan’s hideout. One of the two ninja who had discovered Killer Bee’s defeat had followed him there.

But he didn’t know about Karin’s sensory abilities. He got too close, and right after releasing the tracking lizard, he was killed by Sasuke. The mission to track Sasuke failed with that.

Time rewinds to right after Sasuke defeated Gyuki.

On his way to the Sand Village, Hatake Karasuke thought about the conflict between Sasuke and the Raikage.

Team Samui from the Raikage’s forces would probably head to Konoha soon. They’d deliver the official documents from Kumogakure authorizing the elimination of Uchiha Sasuke to Tsunade.

But right now, there was no time to think about this. The most important thing was Nagato’s attack on Konoha.

But he didn’t know that Obito’s intrusion in the middle had delayed Nagato’s attack on Konoha. Team Samui and Nagato arrived in Konoha at almost the exact same time. But that’s all in the future.

This was something Hatake Karasuke couldn’t prevent. Sasuke going to capture Gyuki was bound to anger the Raikage. The subsequent Five Kage Summit was also unavoidable.

But if he could just stop Tsunade from using too much chakra during the fight against Nagato’s attack on Konoha, that would be enough.

Sakura now should also be able to summon Katsuyu. The size might be much smaller than Tsunade’s, but with him there, the slug Sakura summoned would be sufficient. With all this planned, he had no more worries.

After the tracking was cut off, the Raikage summoned the three members of Team Samui. Besides the captain, the other two ninja, Karui and Omoi, were both students of Killer Bee. They carried swords on their backs identical to Killer Bee’s.

Of course, Killer Bee’s students were much more normal, with just one sword each, unlike his seven. It seems ordinary people really can’t imitate that....

Upon hearing the news that Killer Bee had been captured, both students were shocked.

A cold sweat broke out on Omoi’s face.

"My bad feeling really came true."

"It’s fine. That’s Killer Bee we’re talking about, there’s no way anything happened to him."

"How can you, as students of Lord Bee, doubt our master?"

Their personalities were a stark contrast, just like their names suggested: ’Light’ and ’Heavy’.

"Stop arguing, you two."

The Raikage stopped their childish behavior, though the Raikage himself was already crying. It really didn’t match his imposing figure.

The Raikage truly cared for Killer Bee as a brother. If it were anyone else in the village, his emotions probably wouldn’t have been so shaken.

"Make sure you deliver the documents to Konoha. I will definitely rescue Bee. And along the way, wipe out that Uchiha brat who took him."

"Yes, Lord Raikage."

...

Kumogakure was now in an uproar over Killer Bee. But Killer Bee himself was now wandering freely, humming his favorite raps.

"Got my freedom, honing my rap, can’t forget my teacher Akin, yo~ You’re a bast-ard, you’re an id-iot~."

Even though Killer Bee’s rapping wasn’t good, it didn’t affect his love for it. Sneaking out this time was also to study rap. Killer Bee’s first stop was to find his teacher, Akin.

"Akin? Who’s that?"

"You should learn about my hobbies too, Gyuki."

"He’s the founding father of the ninja rap world, you id-iot, you bast-ard."

Among all the tailed beasts, only Gyuki could probably put up with Killer Bee.

"Speaking of which, when the Akatsuki finds out they were tricked, they definitely won’t let it go."

"Relax, when I’ve rested enough, I’ll go back myself, yo~."

"By the way, you clearly had the upper hand in that last fight. Why did you summon me? There were more energy-efficient ways to fight."

"That Sharingan ninja is one of the best I’ve fought against. I guess I got a little carried away."

In a way, Killer Bee’s words were an acknowledgment of Sasuke’s strength.

Even though his own power was far greater, Killer Bee wasn’t as arrogant as Sasuke. That was the core reason for Sasuke’s defeat.
