The world of Type-Moon starts with saving Altria!

"That depends on the teacher's ability."

Although he was already a veteran, Ian had to admit that what Nero said was very correct.

Everyone is soundly asleep, but she and I are...

"Teacher~"

Nero looked at her husband with love, her eyes filled with indescribable charm.

"Are you satisfied with my performance?"

"Isn't this a matter of course?"

Ian, who was sitting in the driver's seat, kissed Nero lightly on the forehead. This was the simplest way for him to express his emotions.

"Nero... you always fascinate me."

"Is it really like this?" The young emperor tilted her head slightly, looking as if she was drunk.

"of course it's true."

The moment he heard Ian's words, Nero, who originally looked like he was drunk, suddenly raised his head.

"If that's the case, why did you look for that woman?"

"Ok?"

Nero's sudden questioning made Ian stunned.

However, this was not the first time the man had heard such a question.

As the first person to react, Ian quickly realized that the woman Nero was referring to was Nightingale.

He didn't feel panicked at all, but answered very calmly.

"Nero, why do you feel that way?"

"Do you think she and I are already in that kind of relationship?"

"Hmm?"

Nero grabbed Ian's collar.

When she pouts, she looks like a cute little octopus.

"Isn't that right? I saw it clearly just now. She was looking at you the whole time she was talking, right?"

"That's because I'm the only one she knows."

"Nero." Ian looked at the young emperor sitting in front of him and continued to explain.

"I didn't have time to explain it to you guys just now—Nightingale is actually a Servant as well."

"Ok?"

The moment he heard the other party's surprise, Ian felt Nero's heart shrink noticeably.

This is how she behaves when she is surprised.

He realized that Nero had not yet reached the point where he was completely unable to listen to what he said, so he quickly continued to explain.

"In fact, her appearance itself is quite strange—no one summoned her, and she herself had no intention of coming here."

"But I do admire her purpose - she wants to save all the injured."

"Isn't this wishful thinking?" The young emperor criticized Nightingale's behavior without hesitation.

"teacher."

"If a so-called war really breaks out here... then casualties are inevitable."

"And judging by the previous battle, it's very likely that they appeared in large numbers. How could she possibly accomplish such a thing by herself?"

Nero was not slow.

She was halfway through her words when she suddenly realized something.

“Hmm?!!”

"Teacher, didn't you promise her that you would help her achieve this?"

"You really do understand me well."

Ian's hand gently stroked Nero's soft golden hair.

"Yes, just as you said, I did promise her such a thing."

"But don't worry just yet—just listen to my explanation, okay?"

Nero was a little angry that Ian had accurately predicted his behavior, but he still nodded patiently.

"Then tell me!"

"I would like to know what conditions you have to meet in order to agree to something like this."

“It’s not really a condition.”

While answering Nero, Ian recalled what happened when he first arrived at the singularity.

"Actually, I just received some care from her when I came here."

"That's it?"

Nero frowned, and it was obvious that he was quite dissatisfied with this answer.

However, she knew that her teacher would definitely not just make such a statement superficially.

"Hmm! There must be something else that gave you the urge to do this, Sensei?"

"...At times like this, you're quite clever."

Ian put his arm around Nero's waist to prevent her from pressing her whole body against the steering wheel and making strange noises.

“Nero—”

"You should know what a class is, right?"

"Of course I know."

The young emperor proudly showed off her knowledge.

"That is, every Servant has its own corresponding profession when it is summoned, right?"

"For example, I am the most powerful Saber!"

"However, I do want to try Rider's—but it will hurt my butt when I sit on it, so forget it."

"What would you do if I told you that I still don't know what Nightingale's rank is?"

"..."

Nero looked at Ian in front of him and knew that he was not joking.

"How could such a thing happen..."

Just when she was halfway through her words, the young emperor realized something again.

"and many more."

Nero turned around and looked at Nightingale who was sleeping with Ibaraki Douji in her arms.

An expression of surprise bloomed on her face again, like a bunch of roses.

Because she understood the current situation that Ian was talking about.

Even as a Servant, I couldn't even detect Nightingale's class!

This was something I hadn't noticed before because I was busy acting cute to the teacher!

"It seems you finally understand now?"

Ian also followed Nero's movements and looked back.

The nurse with a proud figure now looked a little strange in his eyes.

Or--

It should be mysterious.

It was obviously impossible for her to use the Assassin's common class ability "Breath Blocking" - after all, she had already directly stated her name the moment before they met.

What he did after that was completely consistent with what the name should mean.

That means—

It is very likely that Nightingale has obtained a certain rank that neither Ian nor Nero has ever seen before!

"teacher……"

Nero finally understood at this moment and realized that what his teacher was thinking about was indeed not as simple as it seemed on the surface.

"Are you trying to find out her rank?"

"Absolutely right." Ian nodded, confirming Nero's statement.

"Besides this, there is another very important reason."

"Hmm?"

The young emperor withdrew her gaze from the nurse.

"Is there any other reason? Tell me quickly!"

"I was just about to speak—don't be so hasty."

Ian paused for a moment, then quickly continued his explanation after gathering his thoughts.

"Actually, I talked to her for a while before I found you guys."

"Of course, that was just a chat. Nero, don't think about anything else."

"This legendary nurse once met another saint in her life."

"Oh, no, to be more precise, I saw two saints."

It's not that Ian is talking nonsense.

He and Nightingale did chat for a while on the top floor of the hospital.

It was also because of this opportunity that Ian learned that she had met two Joans of Arc.

He believed that the nurse would not lie about such things.

This means that after the singularity of the Hundred Years' War between England and France was repaired, the direction of history was also repaired.

although--

Ian had no idea what else was going on.

But if you consider everything that your sisters have been exposed to.

Then perhaps she has some intricate connection with Nightingale's undetectable rank.

Furthermore, it might even be because of her that the current situation has occurred.

"This……"

Nero, whose thoughts were guided step by step by Ian, became a little unhappy.

"Why do I feel like the teacher is lying to me... Is this really the case?"

Ian wasn't upset by Nero's reaction.

A man who knows her inside and out knows that this suspicion is actually a sign of her trust.

"Nero, you should know that there is no need for me to lie to you about this kind of thing, right?"

"The situation at this singularity is quite complex. I must grasp every piece of information that might be useful."

"If anything goes wrong, it would be a shame to the entire Chaldea."

This wasn't some impromptu excuse Ian had made up to calm Nero down.

Given that this singularity might contain at least two Holy Grails, it's impossible for Nightingale, who was summoned here as a Servant, to be completely useless.

Of course Ian had to keep her by his side.

"..."
