Studying Hundred Head Slayer

"Ais."

"Brother Shirou!"

"Listen to me!"

"Brother Shirou!"

"It's not what you think!"

"Onii-chan!"

"I understand. I'll teach you!"

Helpless against her, Shirou Emiya ultimately agreed to Ais's request. In the end, he simply couldn't refuse her repeated calls of "Onii-chan."

Even though he couldn't teach it himself.

"Tomorrow morning, meet me in the courtyard. Just wait for me there."

"Mm!"

Seeing that Shirou Emiya had agreed, Ais quickly nodded and stood up from the bed.

She had also noticed how exhausted Shirou Emiya was, so she had no intention of continuing to disturb his rest. Instead, she lightly walked toward the door.

However, just as she was about to leave Shirou Emiya's room, she suddenly turned around and said, "Take care of yourself, Brother!"

With that, she disappeared from Shirou Emiya's sight.

"Phew, she finally left. What a clingy little fairy."

Lying comfortably on his soft bed, Shirou Emiya couldn't help raising an arm to cover his eyes.

Although he was extremely tired, he couldn't fall asleep no matter what.

Thoughts about Ais kept circling through his mind.

Especially those repeated calls of "Onii-chan." They had practically melted Shirou Emiya's heart.

Thinking of this, the corners of Shirou Emiya's mouth lifted slightly, and his smile was exceptionally smug.

At dawn, when the sky was still only faintly bright, Shirou Emiya had already gotten up and finished preparing.

"Given Ais's personality, she's probably already waiting there by now."

He quickly walked down the stairs and arrived in the courtyard. Just as he had expected, Ais's figure was already there.

"You're really impatient."

"Mm. I'm in a hurry, Brother."

Ah, this was no good. Whenever he saw Ais call him "Brother" with that expressionless face, he felt like teasing her.

No, it seemed he was already teasing her.

After all, although he hadn't been the one to make her call him Brother, it could still be considered coercion in a certain sense.

But he simply couldn't refuse her.

Shirou Emiya's thoughts grew chaotic, and he hurriedly raised his hands to pat his cheeks and clear his head.

"Ais, before I teach you the sword technique, there are some things I need to tell you first."

Ais had been tilting her head in confusion over why Shirou Emiya was hitting himself. Upon hearing his words, she immediately became serious. She was full of anticipation for that powerful Martial Arts.

"Yesterday, when I said I didn't know it, I wasn't refusing you. I truly had never mastered that Martial Arts."

Seeing Ais's increasingly puzzled expression, Shirou Emiya paused before continuing, "You may not know this, but when my Projection Magic projects a weapon, it can project not only the weapon itself, but also the experience attached to it. It can even project certain special abilities."

"As for that Martial Arts, I've already learned it, but I haven't reached the level of delivering nine slashes with a single strike. The reason I was able to use that attack was because of that weapon."

"So I wasn't deceiving you. I haven't mastered this Martial Arts either."

Hearing Shirou Emiya's explanation, Ais's expression visibly fell.

"I'm sorry. I was being too selfish."

Looking at the regret and disappointment filling that originally expressionless face, Shirou Emiya couldn't help feeling a pang of sympathy.

Like himself, who had an enemy such as Julian, Ais also had an enemy she had to defeat—the One-Eyed Black Dragon.

Both of them were walking the path of pursuing power in order to defeat their enemies.

Whenever Shirou Emiya looked at Ais, he could always see his own reflection in her.

"Don't apologize just yet. I haven't finished speaking!"

After pulling Ais out of her regret, Shirou Emiya continued, "Didn't I say that although I haven't learned this Martial Arts yet, I already know how to train in it?"

"After all, I read the original owner's experience. So, are you willing to study this Martial Arts together with me?"

"Study it together?"

"That's right, together!"

This was the solution Shirou Emiya had thought of: studying it together.

At the end of the day, Hundred Head Slayer was a school of Martial Arts. Although neither of them had a teacher, they could cultivate on their own.

With Uncle B's experience, Shirou Emiya believed he wouldn't go astray.

"What do you think? Are you willing?"

Looking at Shirou Emiya's outstretched hand, Ais grasped it without any hesitation.

"I'm willing, Brother!"

Ais would never reject any power she could obtain. She was filled with longing for everything.

She had to defeat the Black Dragon.

"Now that we've reached an agreement, let's begin training. I still have to go to the Blacksmithing Room this morning to forge equipment!"

After walking with Ais to a nearby bench and sitting down, Shirou Emiya began explaining Hundred Head Slayer.

He taught Ais the fundamentals through verbal explanations and demonstrations.

And so, one of them spoke while the other listened, and time quickly passed.

From that day onward, Shirou Emiya's life became busy once more.

Every morning after waking up, he studied Hundred Head Slayer with Ais. In the late morning, he had her practice on her own while he went to the Blacksmithing Room to forge his equipment.

After returning in the evening, the two of them studied it together again.

Although Shirou Emiya wasn't as diligent as Ais when it came to studying Hundred Head Slayer, Ais still didn't progress as quickly as he did in Martial Arts.

After all, Shirou Emiya had read Uncle B's experience.

With the boost from that experience, Shirou Emiya's progress could only be described as astonishingly rapid.

Moreover, during their studies, Shirou Emiya discovered another cheat that assisted his training: Mind's Eye.

"Mind's Eye":

increases perception

the information obtained as a basis to predict the opponent's actions

seize every possibility of a reversal and execute it through tactics

With his greatly enhanced perception, Shirou Emiya learned every technique many times faster than before. It felt somewhat like the Sharingan from the world of Naruto.

The only difference was that he couldn't learn Hundred Head Slayer at a glance like he could with the Sharingan.

However, this wasn't because Mind's Eye's perception was inferior to the Sharingan's. It was because the Martial Arts systems of the two worlds were different.

The taijutsu of the Naruto world was essentially training the body, with the exception of the Hyuga clan's Gentle Fist.

Even the strongest Eight Inner Gates only increased all attributes and chakra, didn't it?

But this Martial Arts from the Type-Moon world clearly developed in a different direction from the taijutsu of the Naruto world. This Martial Arts placed greater emphasis on "technique"!

It could unleash nine attacks simultaneously.

Hundred Head Slayer wielded by complete Heracles could even fire nine beams of light.

Tsubame Gaeshi used by Sasaki Kojirō involved interference with parallel spaces.

How could such Martial Arts be learned at a glance through perception alone?

Although Mind's Eye's perception couldn't let Shirou Emiya learn Hundred Head Slayer at a glance, it still allowed him to progress far beyond Ais.

As a result, Ais often went to Shirou Emiya's Blacksmithing Room to ask him for guidance.

Because of this, Loki, who had been without Ais's company during this period, became especially resentful.

"Hehehe, Ais-chan was carried off."

Listening to Loki repeat that sentence endlessly beside him, Shirou Emiya felt a chill run down his spine.

For this reason, Shirou Emiya specially called in reinforcements.

"Shirou and Ais are both working hard to improve themselves. Stop interfering with them here."

Watching Riveria drag Loki away, Shirou Emiya sighed deeply. "Peace and quiet really are wonderful."
