Konoha's Tag-System Ninja

Chapter 57: Chapter 57: Yin Seal and Eight Trigrams Seal!

The Yin Seal technique originated from Tsunade's grandmother, Uzumaki Mito.

It could be said that this technique belongs to the Uzumaki Clan, but in reality, no member of the Uzumaki Clan had ever practiced it before Uzumaki Mito.

This was because Uzumaki Mito herself was the creator of the technique.

The reason she chose to place it on the forehead was naturally due to the fact that the tailed beast within her was sealed in her abdomen.

In fact, the Yin Seal was originally developed as a countermeasure against the Nine-Tails, using a vast amount of chakra to suppress it.

The Nine-Tails had been sealed within Uzumaki Mito for so long without causing any issues and was thoroughly subdued—not only because of Mito's own strength but also due to the effectiveness of the Yin Seal.

Of course, Tsunade didn't mention any of this to Shūichi Hoshita.

Instead, she said, "There's no problem with placing the Yin Seal on the abdomen, but how do you plan to address the issue we discussed last time?"

She had a solution in mind, but she wanted to test Shūichi's understanding.

Shūichi smiled and replied, "Lady Tsunade, you're surely familiar with the Four Symbols Seal."

"I once asked Minato-sensei about sealing techniques, and he taught me this particular seal."

"So, my idea is to use two Four Symbols Seals in conjunction with the Yin Seal to create a cycle—one seal for intake and the other for output, ensuring they don't interfere with each other."

Tsunade fell into deep thought, her mind already beginning to piece together the combination of the three seals.

After a moment, she nodded, "Technically, this seems feasible."

"And this design does indeed suit you better."

"However, it does add a significant level of difficulty. Besides mastering the Yin Seal, you'll also need to learn the Four Symbols Seal, which will require more time."

Shūichi chuckled, "Although I do feel like my chakra is insufficient at times, I'm not even seven years old yet—there's no rush!"

Tsunade, seeing his confidence, didn't argue further and nodded, "Alright, let's proceed with this plan."

"You can ask Minato to teach you the Four Symbols Seal."

With that, she cracked her knuckles, the joints popping loudly, "Since you're not learning the Yin Seal today, let's resume our sparring from before!"

"Your control over chakra bursts is still quite unrefined."

Shūichi's eyelids twitched, and he quickly responded, "Wait, Lady Tsunade."

"Although placing the Yin Seal on the abdomen is a good idea, it doesn't mean I should abandon the previous approach."

Why choose when you can have it all?

...

At the residence of the Nine-Tails Jinchūriki.

Jiraiya found Minato Namikaze there, studying sealing techniques with Kushina Uzumaki.

Minato was thrilled to see Jiraiya, "Jiraiya-sensei, you're finally back!"

"Yes!"

Reflecting on his time in the Land of Rain, Jiraiya smiled warmly, "It was a very special journey."

"So, Minato, have you completed that idea you mentioned a while ago?"

Hearing this, Kushina, who had just brought tea, chimed in, "Jiraiya-sensei, are you talking about the Rasengan?"

"Rasengan?"

Jiraiya, eager to see it, said, "As expected of Minato—looks like you've finished it. Show me quickly!"

Minato smiled, "If it weren't for Shūichi, I wouldn't have completed it so quickly."

"Shūichi is the student I'm currently mentoring—an exceptionally talented and outstanding ninja!"

At this, the image of that polite, gentle, and well-mannered kid popped into Jiraiya's mind, and he realized, "So it was him! No wonder Tsunade took a liking to him; he seems quite remarkable!"

"Oh, Jiraiya-sensei, you've already met Shūichi?"

"Yes, Shūichi has indeed gained Lady Tsunade's favor. His talent in medical ninjutsu is also exceptional—he's already become a fully capable medical ninja."

Minato Namikaze was full of praise.

Jiraiya smiled and said, "It seems like you've taken a special interest in nurturing him, Minato."

There's a difference between a student and a personal disciple.

"That's true!" Minato admitted, then extended his right hand and opened his palm. "But for now, let's take a look at the new jutsu!"

Buzz! The air stirred as the blue Rasengan rapidly formed in his hand.

Jiraiya's eyes widened. "What a perfect jutsu, and it suits you so well!"

Kushina Uzumaki, hands on her hips, interjected, "Jiraiya-sensei, this jutsu was developed by Minato for me, and it's most suited for me!"

Jiraiya, not wanting to provoke the fiery Kushina, quickly laughed, "Of course, of course! This jutsu is just right for dealing with that Nine-Tails."

"The power of this technique is entirely determined by the amount of chakra you put into it."

Kushina sighed, "Right now, all my chakra is being used to suppress that pesky Nine-Tails. Otherwise, I could store chakra using the Yin Seal."

Minato quickly reassured her, "Once you master the Adamantine Sealing Chains technique even better, you'll be able to suppress the Nine-Tails more effectively."

"Also, your chakra reserves haven't yet reached their peak, while the Nine-Tails won't get any stronger."

Hearing this, Kushina immediately brightened up and smiled, "That's true."

"Hmph, when the time comes, I'll make sure to give that Nine-Tails a good lesson."

Watching the two, Jiraiya couldn't help but think to himself, They really are a perfect match.

One is oblivious, and the other is sincere!

...

After returning home from the Konoha Hospital, Shūichi Hoshita officially began training in the Yin Seal.

Simply put, the Yin Seal involves creating a chakra storage area at the point between the eyebrows, which can be thought of as a reservoir, with chakra being the water.

However, unlike Tsunade, Shūichi needed to create two reservoirs—one large and one small.

The larger one was specifically for storing chakra to be used in critical moments.

The smaller one was for everyday use.

Although this approach was somewhat cumbersome, until he mastered the Four Symbols Seal and Eight Trigrams Seal, this was the best he could do.

Unlike when he used the Memory Palace Seal, Shūichi's skills in sealing techniques had significantly improved.

He no longer needed to pre-draw the sealing script before using it. Instead, he could use hand seals to assist in transforming his chakra into talismans, forming the sealing script.

Still, it took him a full minute to complete the hand seals.

"Yin Seal!"

As he completed the final hand seal, Shūichi brought his hands together, and his body was immediately covered in dense, tadpole-like symbols.

These symbols then converged toward his forehead, forming the Yin Seal mark before it faded from sight.

Afterward, Shūichi lowered his eyes and began refining his chakra, channeling it into the two reservoirs within the seal.

On October 6, Year 39 of the Konoha Calendar, Shūichi Hoshita officially began training in the Yin Seal!

To better develop new jutsu and achieve the [Medical Expert] tag, Shūichi started reducing his missions outside the village. Most of his time was spent at the Konoha Hospital or training within the village, occasionally going on missions with Minato and the others.

Before he knew it, the temperature began to drop, signaling that autumn was deepening.

One day, feeling exhausted, Shūichi invited Tsunade to relax at a hot spring, but when she declined, he decided to head to Konoha's hot spring street alone for some well-deserved relaxation.

"Huh?"

Shūichi noticed someone on the roof.

"That old pervert Jiraiya..."

Shūichi stopped in his tracks.

Peeping? How immoral! This definitely needs a stern reprimand.
