In the world of Type-Moon, it all begins with becoming Morgan's husband!

“Tamamo-no-Mae is a fox spirit from the Heian period!” Leonardo da Vinci’s blue eyes were filled with emotion.

“I had learned about this amazing era from the books of Chaldea—I never imagined that I would see something from that era today!”

"I'm so lucky!"

Unlike those who become heroic spirits because of various obsessions, Leonardo da Vinci pursued "learning" itself.

The simplest way to realize this concept is to be exposed to different kinds of knowledge.

and so--

For Leonardo da Vinci, each successful verification of the authenticity of knowledge would bring her great joy.

The appearance of Tamamo-no-Mae was also a means of "verifying the truth," and Leonardo da Vinci naturally welcomed this fox spirit.

By the way.

The last time she was this happy was when Mordred—that mischievous girl confirmed the authenticity of ancient Britain, much like Tamamo-no-Mae at this moment.

Encountering people from different eras may be one of the reasons why Leonardo da Vinci, as a heroic spirit, remained in Chaldea and never left.

"is it?"

Tamamo-no-Mae gave a charming smile.

"I am truly moved to see Leonardo da Vinci welcome me so warmly."

"but--"

The fox demon took Ian's arm beside her.

"My Master seems to have something he wants to say to you."

"Da Vinci, sir... can we talk another time?"

"..."

Ian looked at Tamamo-no-Mae nestled beside him, his expression somewhat complicated.

He knew that her understanding was not as simple as it seemed—it was a survival instinct developed from long-standing fear and anxiety.

She lived her life on thin ice.

Without such keen perception, he would probably have died a violent death long ago.

Thinking of this, Ian couldn't help but feel even more sorry for her.

The hand that was holding hers had become a little stronger.

Feeling this, Tamamo-no-Mae silently accepted his concern, and her fox tail swayed slightly behind her.

"Yeah, sure."

Although he was very happy, Leonardo da Vinci could still distinguish between work and idle chatter.

Her gaze fell on Ian, and a smile appeared on her face—she was actually quite grateful to the Master who had summoned Mordred and Tamamo-no-Mae.

"Ian, what's wrong?"

Back to the main topic, Ian took a deep breath and composed himself.

“Da Vinci, I would like to ask you some questions about the ‘Heroic Spirit Summoning System’.”

"Eh?"

Leonardo da Vinci blinked.

It seems she didn't expect Ian to say such a thing, but it wasn't unacceptable to her.

The all-knowing person nodded and then replied, "What is the question?"

"that is--"

Ian looked up at the mysterious sphere floating above the hall.

"Can I still use it for summoning?"

If there is someone you really want to see.

But he also knew that he had a way to see her.

So what would your choice be?

Ian's choice was to act.

As he spoke, the image of the figure sitting on the throne appeared before his eyes.

If there is a chance—

If possible—

Even if it's just one side—

He also wanted to see her again.

However, Ian's idea was quickly shattered by Leonardo da Vinci.

The all-powerful man sighed, shook his head, and answered.

"I'm sorry, Ian."

"Although I really wanted to say 'yes'."

"but--"

You can't do that anymore.

As Leonardo da Vinci said this, he slowly raised three fingers.

"First, the fact that Tamamo-no-Mae is experiencing this problem indicates that my method of fixing the 'Heroic Spirit Summoning System' has flaws."

"Until I figure out how to solve this problem... I absolutely cannot let you take any more risks!"

"Secondly, the magic of the Holy Grail brought back from the singularity is also almost used up."

"If we rashly use the Heroic Spirit Summoning System under these circumstances, I'm not sure if something terrible might happen."

"Ian...you don't want to summon some weird or strange things, do you?"

"Third, and most importantly!"

Da Vinci's gaze fell on Ian, and he looked quite worried.

Even if none of the previous problems affected you.

"But if you keep summoning like this, you'll have three Servants... Are you sure your mana reserves can support that?"

"I don't want to see Ian fall down because of something like this."

"..."

It must be said that every word Leonardo da Vinci uttered precisely pointed out the key points.

The problems inherent in the "Heroic Spirit Summoning System";

The exhaustion of the Holy Grail at the Singularity;

And the supply of mana between Master and Servant.

Both of these points are indeed things that need to be considered right now.

"I see." Ian composed himself.

“Nada Vinci, I have another question.”

"It's not still the 'Heroic Spirit Summoning System', is it?" Da Vinci put his hands on his hips.

"Ian, I think I've made myself clear. No matter what you say, it's not going to work."

“No.” Ian smiled and shook his head.

"That's not what I was asking about."

“Well—” Leonardo da Vinci frowned slightly, then asked, “What is the problem?”

"Um……"

Ian’s gaze fell on Olga Marie, who was standing to the side.

"I was thinking, since the director's body can be replicated by an 'omnipotent person'—"

"Then, could I also use my memories to recreate the Noble Phantasms from the past in the same way?"

“Memory projection” is not without its costs.

After using them multiple times, the man could clearly feel that his memories of the copying artifacts he frequently used were gradually becoming blurred.

Especially Excalibur Morgan, which is used the most, feels like something you might forget at any moment.

If we could "create" these weapons, which have become Noble Phantasms, in the same way we created the body for the director, then perhaps we could avoid the side effects of "memory projection."

however--

Ian's idea was once again rejected by Leonardo da Vinci.

"That won't work either, Ian."

“Even if something created by my Noble Phantasm ‘Omnipotent Man’ is indistinguishable from the original in appearance, it cannot be used as a ‘Noble Phantasm’.”

"Because 'Noble Phantasm' is a concept, and its physical form is only a part of that concept."

"If you only have the physical form but don't obtain the other parts of the 'Noble Phantasm,' then it's just an empty shell."

"This is completely different from what the director needed back then."

"That's it..."

Ian's expression was somewhat complicated after his idea was rejected by Leonardo da Vinci once again.

He certainly couldn't blame her.

However, this situation was still somewhat regrettable for him.

After all, if we could replicate all sorts of Noble Phantasms through Leonardo da Vinci's "omnipotent person", we wouldn't have to worry about not having a suitable weapon in the future.

This will also better protect them.

At that moment, Ian felt a warm sensation on his cheek.
