Muzan's Bloodline Limit

Kakashi had been in pain and bliss these past few days. At Muzan's urging, Might Guy often came to spar with Kakashi, even though he lost every time.

"Damn it, Muzan! This is all your fault! That green watermelon head actually ambushed me while I was using the bathroom!"

The furious Kakashi did not even call him brother anymore. All he wanted was revenge—to teach Hatake Muzan a lesson.

"Don't say that. Have you seen what a hardworking genius is like? Feeling the pressure now?"

Muzan caught a faint scent of blood. Clearly, Kakashi had not come out unscathed from fighting Guy and had suffered a few superficial wounds. To make Kakashi stronger, Muzan decided to teach him a powerful move.

"The Hatake Household's strongest technique isn't swordsmanship, but a move called Thousand Years of Death. Now I'll teach you how to use it!"

"Really? It's even stronger than the Hatake Sword Technique?"

After their recent clashes, Kakashi could clearly feel Guy's strength rapidly improving. Perhaps before long, they would be evenly matched.

Just as Muzan was preparing to teach Kakashi the secrets of Thousand Years of Death, an imposing voice came from outside the door.

"Nonsense!"

Sakumo entered with a dark expression, having overheard his two sons. Why did he have such bizarre sons?

Sakumo had worked hard to build up the Hatake Household's reputation, and he could not let them ruin it. However, when he looked at Muzan, Sakumo Hatake still spoke patiently.

"For the time being, train properly with Nobi Wei. And you two little brats, the way you act at school will never earn you any friends. Pay attention to your relationships with others."

Sakumo Hatake wore the troubled expression of an old father, afraid that his two children would never find wives and the Hatake Household's lineage would end.

"I still don't understand why I have to attend school. I can obviously apply for the Genin exam already."

Every day, he had to play around with those little brats at school. Especially that girl named Rin Nohara, who only ever wanted to talk to him—and that idiot Obito!

"Now isn't the time to apply."

As a Kage Level powerhouse, Sakumo Hatake could sense the tension between the major ninja villages. Conflicts might break out before long, and becoming a Genin now was far too risky.

"Where the leaves of Konoha dance, the fire burns on."

Even if war came, people like them would be the first to charge forward.

The day's meal was brought to the table. After a tiring day, it was time to rest properly at night.

"By the way, why isn't there any rabbit meat today?"

Kakashi remembered that when they came home from school, Muzan had bought a rabbit from the pet shop. He had thought they would be having rabbit meat today, but there was not even a scrap of meat on the table.

"The rabbit? I'm using it for an experiment. You know my Bloodline Limit has awakened, so I need to test it."

He got up and brought the rabbit over from behind the door. Seeing its trembling body, Sakumo once again sensed the danger of some wild beast. Muzan's Bloodline Limit seemed terrifying indeed.

As for whether the Hatake bloodline could truly awaken, he was only in his early thirties. He could still have a few more children, and perhaps then they could become a bloodline clan as well.

The rabbit being stroked tried to struggle free, but a mouth suddenly appeared in Muzan's palm and bit into the rabbit's body.

"What kind of bizarre technique is that?!"

Kakashi stared at Muzan's palm, his face filled with horrified revulsion.

"Don't make such a fuss. Bloodline Limits come in all kinds of forms and appearances. Some can alter the body."

Sakumo was not surprised. There were many kinds of Bloodline Limits, and he had seen even more horrifying ones, such as the Kaguya Clan's Dead Bone Pulse, which had already surpassed the bounds of humanity.

The mouth was not there to tear apart the rabbit. The instant it pierced the rabbit's body, Muzan's blood was injected into it. In only a short time, the rabbit's body began to rapidly expand.

Sakumo Hatake, who had been sitting to one side, placed his right hand on his sword and stepped in front of his two sons, warily watching the rabbit continue to mutate.

It could no longer be called a rabbit. Under the effects of Muzan's blood, it grew as large as a wild boar, its eyes filled with savage violence as it became a mindless beast.

During the process of turning into a Man-Eating Demon, whether human or beast, there would be a period of madness. Actions taken during that stage were driven by instinct, but they still could not escape Muzan's control.

"Don't worry about the rabbit going mad. Its body can't endure it."

As soon as he finished speaking, the rabbit's body burst into a spray of blood.

"It failed."

Looking at the wrecked room, Sakumo Hatake was not surprised. This power was too strong. For a tiny rabbit to endure it so suddenly, lasting even a few seconds was thanks to Muzan. Still, this Bloodline Limit seemed more suited for support, increasing the strength of others while offering no benefit to its user.

Worried that Muzan might take the failure badly, Sakumo Hatake reached out to rub his head, only for Muzan to dodge. He assumed Muzan was sulking.

"Don't lose heart. A temporary failure won't be decisive. A ninja's strength is the result of many factors. Study the Hatake Sword Technique properly, and your future achievements will not be low."

"Father, you have it backward. I'm not disappointed."

What a joke. He simply was not used to being treated like a child and having his head rubbed. As for the failure, it was not because his Bloodline Limit was too weak. On the contrary, the rabbit simply could not withstand that power.

More importantly, the Man-Eating Demons Muzan created were under his control. Just thinking of the strength of the Twelve Kizuki and their terrifying regenerative abilities, this was a top-tier bloodline!

Though inwardly thrilled, Muzan quickly calmed down. Noticing the state of the room, he suddenly pretended to be unwell, his face pale and weak as he said,

"Father, perhaps it's the side effect of using my Bloodline Limit just now, but I'm feeling a little unwell. I'll go back and rest first."

Sakumo Hatake was about to say all right, but the moment he opened his mouth, he saw Muzan grab Kakashi and dash out the door.

"You brat! Get back here and clean up the room!"

"These two little bastards!"

Though he said that, Sakumo could not hide the smile at the corner of his lips. Muzan had now mastered a power of his own. It was time to teach him the Hatake Sword Technique.

Outside, beneath the moonlight, Kakashi wore a complicated expression as he looked at Muzan, who shared the same white hair. After thinking for a moment, he did not know how to say it.

"What is it, Kakashi?"

"Brother, if possible, I want to spar with you."

After spending this time together, Kakashi had keenly sensed that Muzan's body was undergoing earth-shaking changes. Especially at school, he had noticed Muzan deliberately controlling his chakra.

Using chakra nonstop for an entire afternoon—what kind of stamina was that?

Perhaps the brother he had always overlooked was a true powerhouse.
