Studying Hundred Head Slayer

"Ais."

"Onii-chan!"

"Listen to me!"

"Shirou Onii-chan!"

"It's not what you think!"

"Onii-chan!"

"I understand, I'll teach you!"

Helpless, Shirou Emiya eventually agreed to Ais's request. He simply couldn't refuse the calls of "Onii-chan."

Not even he himself could.

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

"Okay!"

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

She could see how tired Shirou Emiya was, so she didn't intend to disturb his rest any longer. Instead, she skipped lightly towards the door.

However, just as she was about to leave Shirou Emiya's room, she suddenly turned back and said, "Please take care of yourself, Onii-chan!"

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

"Hoo, she's finally gone. What a clingy little imp."

Comfortably lying on his soft, large bed, Shirou Emiya couldn't help but raise an arm to shield his eyes.

Despite being exhausted, he couldn't fall asleep now.

Thoughts about Ais kept swirling in his mind.

Especially those calls of "Onii-chan," which had completely melted his heart.

Thinking of this, the corners of Shirou Emiya's lips couldn't help but curve upwards slightly. This smile was exceptionally smug.

Early morning, just as dawn was breaking, Shirou Emiya was already up and ready.

"Knowing Ais's personality, she's probably already waiting for me there by now."

He quickly went downstairs and into the courtyard. As Shirou Emiya had expected, Ais's figure had already appeared in the courtyard.

"You're quite impatient."

"Yes, I'm very eager, Onii-chan."

Ah, no, I can't. Seeing Ais call me "Onii-chan" with a poker face like this feels like I'm bullying her.

No, I am bullying her.

After all, even though this "Onii-chan" wasn't something I made her call me, it was still a form of coercion in a way.

But I still can't refuse it.

His mind in turmoil, Shirou Emiya quickly reached out and patted his cheeks to wake himself up.

"Ais, before I teach you swordsmanship, there are some things I need to tell you beforehand."

Ais, who was tilting her head in confusion as to why Shirou Emiya was hitting himself, immediately became serious upon hearing his words. She was very much looking forward to that powerful martial art.

"When I said I couldn't yesterday, I wasn't refusing you. It's just that I truly hadn't mastered that martial art."

Looking at Ais's increasingly confused gaze, Shirou Emiya paused and continued, "You might not know this, but when my Projection Magic projects a weapon, it can not only project the weapon itself but also the experience attached to it. Along with some special abilities."

"Regarding that martial art, I have learned it, but I haven't reached the level of 'nine slashes in one strike' yet. The reason I was able to use that strike was also because of that weapon."

"So I wasn't lying to you. I haven't learned this martial art either."

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

"I'm sorry, I was too willful."

Looking at the apology and disappointment filling her usually placid face, Shirou Emiya couldn't help but feel a pang of sympathy.

Just as he had an enemy like Julian, Ais also had an enemy she had to defeat: the one-eyed Black Dragon.

They were both on the path of seeking power to defeat their enemies.

Looking at Ais, Shirou Emiya always saw a reflection of himself in her.

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

Calling Ais back from her apology, Shirou Emiya continued, "Didn't I say it? Although I haven't learned this martial art yet, I already know how to cultivate it."

"After all, I've already read the original owner's experience. So, are you willing to study this martial art with me?"

"Study together?"

"That's right, study together!"

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

Hundred Head Slayer was, after all, a style. Even though neither of them had a mentor, they could still train themselves.

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

"So, will you?"

Ais looked at Shirou Emiya's outstretched hand and grasped it without hesitation.

"I will, Onii-chan!"

Ais wouldn't refuse any power she could obtain; she was full of desire for everything.

He wanted to defeat the Black Dragon.

"Since we've reached an agreement, let's begin training. After all, I still need to head to the forge this morning to craft equipment!"

After walking to a nearby seating area with Ais, Shirou Emiya began his explanation of Hundred Head Slayer.

He imparted basic knowledge to Ais through verbal instruction and gestures.

And so, as one spoke and the other listened, time quickly slipped away.

From this day forward, Shirou Emiya's life became even more demanding.

Every morning after waking up, he would study Hundred Head Slayer with Ais. In the morning, he would let her train on her own while he went to the forge to craft his own equipment.

When he returned in the evening, they would study together again.

Although Shirou Emiya wasn't as diligent as Ais in their study of Hundred Head Slayer, Ais didn't improve as quickly as Shirou Emiya in terms of martial arts progress.

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

With the boost from this experience, Shirou Emiya's progress was astonishingly rapid.

Furthermore, during this study, Shirou Emiya discovered another cheat skill to aid his training: Mind's Eye.

"Mind's Eye":

· Greatly enhanced perception

· Predict the opponent's actions based on gathered information

· Seize opportunities and execute tactics for any potential reversal

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

However, it wasn't possible to instantly learn martial arts like Hundred Head Slayer with it, unlike the Sharingan.

But this wasn't because Mind's Eye's perception was inferior to the Sharingan's; it was because the martial arts levels in different worlds were different.

The essence of taijutsu in the Naruto world was physical training, with the exception of the Hyuga clan's Gentle Fist.

Even the strongest Eight Inner Gates, wasn't it just about improving all stats and chakra?

But this martial art from the Type-Moon world clearly had a different development direction than the taijutsu of the Naruto world; this martial art placed more emphasis on 'technique'!

Simultaneously delivering nine attacks.

The fully realized Hercules' Hundred Head Slayer even fired nine beams of light.

Sasaki Kojiro's Tsubame Gaeshi, for example, involved interference with parallel space.

How could martial arts like these be learned with mere perception alone?

Although Mind's Eye's perception couldn't allow Shirou Emiya to learn Hundred Head Slayer instantly, it still enabled his progress to far surpass Ais.

This often led Ais to visit Shirou Emiya's forge to ask him for advice.

As a result, Loki was exceptionally sullen during this time without Ais's company.

"Heh heh, Ais-chan's been snatched away."

Hearing Loki repeat this phrase incessantly by his ear sent a chill down Shirou Emiya's spine.

For this reason, Shirou Emiya specifically called for external assistance.

"Shirou and Ais are both working hard to improve themselves, so don't bother them here."

Watching Riveria drag Loki away, Shirou Emiya deeply sighed, "Quiet is good."
