Flying Thunder God Slash

After drinking too much, sleep came especially sweet. He hadn't used Chakra to sober up—otherwise, wouldn't the drinking have been for nothing?

Kawafune slept until dawn. With no pressure on his mind, he slept well.

He felt like he was holding something, and it was quite comfortable.

Kawafune reached out and gave it another squeeze. So soft.

He sat up and opened his eyes. Wasn't this the Ghost Mastiff? Why was it sleeping in his bed?

With a look of disgust, he kicked the still-sleeping Ghost Mastiff off the bed. He only vaguely remembered grabbing it and making it carry him back to his room.

The moment he collapsed onto the bed, he had no memory of anything after that.

"Awoo!"

The Ghost Mastiff hit the floor and woke up in pain. Who had ambushed this dog?

It looked up and met Kawafune's puzzled gaze. Then it turned its head and saw that it had spent the entire night sleeping in hell—and had even been held by this detestable guy.

"Awoo!"

This dog's body was no longer clean. Hopefully it wouldn't affect its chances of finding a pretty female dog.

The Ghost Mastiff bolted from Kawafune's room and vanished from his sight in the blink of an eye, perfectly displaying the prowess of a Ninja Dog.

Kawafune couldn't be bothered to think about it any further. What was there to think about after hugging a dog? It wasn't like he had spent the night holding Tsunade.

He got up and washed up, reeking of alcohol. He had no idea what time Nawaki would arrive.

Kawafune definitely had to make the most of this brother-in-law connection.

Sakumo, who had a wife, had long since gone to train in the Training Hall. Only a single younger brother deserved to sleep in.

Ever since the family became wealthy, the Hatake Clan's quality of life had soared. That was probably why the Ghost Mastiff had gained over ten pounds in just a few years.

With a casual instruction, a lavish breakfast was brought to the table, and Kawafune ate to his heart's content.

Just as he was about to have another bowl of porridge, his sister-in-law's voice came from outside.

"Kawafune, guests from the Senju Clan have arrived."

"I've arranged for them to wait in the Living Room."

As a member of one of Konoha's elite clans, his sister-in-law still held the Senju Clan in high regard.

As soon as she finished speaking, she appeared in the dining room as well.

"Alright, I'll go right away."

He had just been thinking about them, and now they were here. Kawafune took another sip of porridge, wiped his mouth, and left with his sister-in-law.

He had assumed only Nawaki would be waiting in the hall, but upon arriving, he found his older brother talking with Tsunade, while Nawaki and Kushina sat off to the side.

This brother-in-law hadn't been acknowledged for nothing. He was truly reliable.

Tsunade still wore a short inner outfit beneath a green coat. Her pale blonde twin ponytails were especially beautiful, and her cleavage remained just as eye-catching.

The atmosphere in the entire Living Room was somewhat strange. Tsunade and Sakumo simply had nothing to talk about. It was painfully awkward small talk.

The moment he saw Kawafune arrive, Sakumo breathed a sigh of relief. Socializing was better left to his younger brother.

"Kawafune, Tsunade came to see you."

"Now that you're here, I'll go take care of something."

After saying that, he hurriedly greeted Tsunade and slipped away.

He left his wife and younger brother standing there in disarray. With the way he was, the fact that Kakashi could become Hokage was entirely due to his own ability, alright!

"Ahem."

"My brother may have gone to deal with something urgent. Sister-in-law, you should go check on him too."

Kawafune immediately sent his sister-in-law away. He couldn't properly work his magic with someone else around.

Nayuki had no idea what her brother-in-law was up to, but she greeted them as well and headed in the direction her husband had gone.

"Tsunade-chan, I didn't expect you to come too."

Only then did Kawafune put on a smile and sit where Sakumo had just been.

"Big Brother, I was the one who asked my sister to come."

Nawaki was unhappy. This was clearly his contribution, so it couldn't just be erased like that.

Kushina was unusually well-behaved as she sat in her chair, her eyes flickering. She felt that this Big Brother Kawafune was suspicious.

"Kawafune-kun, Nawaki came to your door to learn from you. As his sister, I should show some sincerity as well."

"I brought you a gift today. I hope you'll like it."

Tsunade reached between her breasts, pulled a scroll out from behind her back, and placed it before Kawafune.

"What is this?"

Kawafune was a little unsure. He had no idea what the scroll contained.

"Haha, it's only a ninjutsu developed by my Second Grandfather."

"I thought it suited you well, so I brought it over."

"Why don't you see whether it suits your tastes?"

Tsunade had clearly selected it carefully. She hoped to see Kawafune's surprised expression shortly, and she was especially enthusiastic now.

The instant Tobirama was mentioned, Kawafune's first thought was—Impure World Reincarnation. Could this scroll contain such an overpowered ninjutsu? That would be incredible.

Though inwardly impatient, his hands remained steady. Unhurriedly, he picked up the scroll and opened it.

Kawafune's pupils suddenly dilated. This technique truly suited him. It was also the technique he had dreamed of obtaining.

The Flying Thunder God Slash, developed by Senju Tobirama.

His speed had gone without improvement for a long time. If he could learn the Flying Thunder God, his killing power would rise to another level.

"Thank you. This technique is very interesting."

Kawafune put down the scroll and tucked it away close to his body.

"I'm glad you like it."

"However, this technique requires one to comprehend the power of space."

"I hope you can learn it."

Tsunade explained the key to cultivating the Flying Thunder God. Someone without the talent might never learn it in their entire lifetime.

"I will certainly study it diligently and not let the Second Hokage's technique be buried in obscurity."

This is the technique that took out Uchiha Izuna! Madara's own younger brother—the man who could trade blows with Hashirama.

"Nawaki is in your care."

"I'll take Kushina back with me."

Tsunade had delivered the gift for his apprenticeship. Seeing that Kawafune was quite satisfied, she prepared to take her leave.

"You've come all this way."

"If you don't stay for a meal, people might think the Hatake Clan can't even afford to treat guests to food."

Kawafune was simply talking nonsense. The Hatake Clan was rich now; probably everyone in Konoha knew it.

With such a large Weapon Shop, who would believe they weren't making money in this era?

"Then I'll accept your hospitality."

Since one offered and the other was willing, Tsunade did not refuse and agreed as she spoke.

Kushina had been reluctant when she heard they were leaving, but now a smile appeared on her face too. Going out was far more interesting than learning Sealing Jutsu with Mito.

"Big Brother, I want to learn the sword! Learn the sword!"

Nawaki had kept silent out of fear of his sister's strength, but now he could no longer hold himself back.

"Then let's go. We'll take a look at my family's Training Hall."

Kawafune said this to Tsunade. In front of his sister, this brother-in-law was worth less than nothing.

"Alright."

Tsunade agreed with a smile. She rose and followed Kawafune as the two adults and two children left the Living Room for the Training Ground.

In the Training Hall, Sakumo was practicing taijutsu. His new blade had yet to be forged, so he could only train his body for now.

Nayuki was also training the Ghost Mastiff. One person and one dog moved in perfect unison, displaying incomparable coordination.

"The Training Hall is still a little too small. I'll expand it when I get the chance."

The Hatake Clan's Training Hall was larger than the Senju Clan's, yet Kawafune still complained that it was too small. He might as well have written the words "showing off wealth" on his face.

Tsunade showed no reaction on the surface, but inwardly calculated how long this would be enough for her to lose.

"Today, I'll teach you something else and see whether you have talent for Sword Art."

Looking at the impatient Nawaki, Kawafune took a wooden sword from the weapon rack and handed it to him.

The moment the wooden sword entered his hand, Nawaki felt its weight. It was made from Ironwood.

"There are eight basic movements in total. I'll perform them once. Watch carefully."

With a raise of his hand, the Eight-Faced Han Sword was already in Kawafune's grasp.

"Watch carefully."

"Thrust, chop, sweep, hang, circle, point, flick, intercept."

Since he had the small intention of looking cool in front of Tsunade, Kawafune made the eight basic movements look especially impressive. His attacks were imposing, and his defense was ingenious.

"Kawafune-kun, your Sword Art is excellent."

Tsunade generously applauded him. Sure enough, handsome men looked this good even when practicing the sword.

Kushina's eyes were practically sparkling. If Minato knew Sword Art too, he could be this handsome as well.

"Big Brother, you were too fast."

"Slow down and do it once more."

Nawaki suffered for it. He didn't have Copy Eyes; he had only remembered the beginning and end of the eight movements.

"What do you mean, too fast? That's called fluidity."

Kawafune seemed unwilling to hear Nawaki say that, so he raised his hand and demonstrated once more in slow motion.

The spectacle immediately dropped several levels, though it was much better for teaching.

Holding the wooden sword, Nawaki clumsily copied the movements.

"Raise your hand higher, lower your center of gravity, keep your legs steady..."

Kawafune corrected Nawaki's improper movements. Not bad—being a teacher felt pretty good.

Watching Nawaki study seriously under Kawafune's guidance, Tsunade felt that his handsomeness had risen another level.

What, did this woman have some kind of professional filter?
