The world of Type-Moon starts with saving Altria!

BB was circling around Ian, her eyes looking worried and scared.

"Pig——"

"You're not missing any parts, are you?"

"Don't lie just to make BB and the others less worried."

"Does this sound like a lie to me?"

Ian knocked BB on the head.

"In fact, I came out just like that, without missing anything!"

What the man didn't expect was that just because he said such a simple sentence, BB rushed over directly, buried her head in his arms, and started to rub against him.

Rather than being a cat-like posture, it looked more like the look of a child who had finally gotten back something they loved.

"Great... you're back..."

"BB must be worried to death..."

"..."

Ian now felt a little guilty.

He had thought that BB would be anxiously waiting, but he never thought that the other party would be so scared.

The man hugged the baby in his arms and comforted her softly.

"Do not worry--"

"I won't die that easily. After all, didn't BB say that nothing must happen to me?"

"But Baby is really cute like this, with such rosy cheeks. I really want to admire her for a while longer."

"Eh!"

Realizing that he seemed to have lost his composure, BB quickly took a few steps back.

But soon, she realized that this was not a good thing - it seemed like she didn't like Ian, so she immediately walked back and held his hand.

"Is it not possible?!"

"Didn't you say, pig, that BB can do whatever she wants?"

"That must be when I'm not around."

Scathach inserted a hand very forcefully and forcibly separated Ian and BB.

The Queen of Shadow Kingdom stood before her, then supported her waist with both hands and said:

"do not forget--"

"This time, I was the one who protected her. No matter what, you should thank me first, right?"

"you……"

BB bit his lip.

To be honest, she definitely didn't want to apologize to Scathach in front of her.

But this time, Scathach did do a lot - at least that's what it looked like from her own perspective.

After an extremely painful struggle, BB finally spoke despite the dissatisfaction in his heart:

"Thank you!"

"Be quiet—"

Scathach shook her head.

"Can you speak louder?"

"Thanks!"

"Better be louder."

"Hey!" BB was a little unhappy - he had already tried his best to say thank you twice!

"Don't go too far!"

"Although you have done a lot of things, you are still just a stinky old woman at heart!"

"Who are you calling a stinky old woman?"

"you!"

Scathach and BB were getting closer and closer, as if they were about to start a fight.

Seeing that the war between his girlfriends was about to start again, Ian quickly took action to stop it all.

"All right!"

The man held Scathach and BB's hands on the left and right.

"You two, that's enough—"

"Now, I think I should find out what happened inside."

"Be obedient, okay?"

"..."

"..."

Although they might be dissatisfied with each other in their hearts, they probably also thought that the other party had indeed done a lot in this operation, not to mention that Ian had spoken.

and so--

Neither Scathach nor BB continued to speak too much in the end.

"Pig."

"So tell BB what happened in there."

"it is good."

In the next few minutes, Ian told BB what happened to him and Scathach inside.

of course.

This also includes the mysterious voice heard at the end.

"Wha, what..."

"Did you first cross the 'sea' thing?"

"..."

Realizing that BB seemed to know something, Ian immediately asked.

"BB, do you know something?"

"..."

After a moment of silence, the Super AI Girl continued to answer.

"There's a record of something like this in Chaldea's research materials—there's a magical property called 'imaginary numbers'."

"Once it expands over a large area and forms a certain kind of space, it will be a situation that is very consistent with your description."

"but……"

BB hesitated to speak.

Ian could see that it was the word "imaginary number" that brought her hesitation.

"It doesn't matter, just say whatever comes to mind."

"You should know that what we pursue is the truth, not the other party's feelings."

"Whatever it is, just tell us directly."

"..."

BB was silent for a long time, and finally nodded.

"Just like the source of magic cannot be explored normally, the space formed by 'imaginary numbers' should not be entered casually - after all, it is not a normal place."

"unless……"

"Unless what?" Scathach also became concerned.

“Unless someone creates this space in a way that leaves enough room for latecomers to enter.”

"..."

"..."

The atmosphere suddenly became depressing.

Because both Ian and Scathach realized something.

"You mean-"

"At the moment when Leif exploded, someone created this imaginary space and brought Ophelia in?"

"In theory, it should be like this..."

The Super AI Girl confirmed her master's statement.

"Of course, it's more likely that the appropriate space had already been arranged before this."

"Who can do such a thing?"

Scathach's brows furrowed.

She really doesn't like being "manipulated" by others.

"If so many people don't notice—"

"This is definitely not a simple matter, right?"

"That's not the way it should be..."

BB's throat moved slightly.

"It's difficult to weave it all together in one go, but if we do it over several times, or even start it as Chaldea recovers, the result will be different."

"So, does that mean the voice I heard was most likely the person who did this?"

"maybe."

"..."

"..."

"..."

The atmosphere became even more depressing than before.

The three people present knew what this meant—

It is equivalent to there being someone who has been secretly watching them repair the singularity.

"I say, that person, could it be Marisbury?"

Ian couldn't help but raise the possibility.

"If it's him, then everything is explained clearly, right?"

"It shouldn't be possible."

BB quickly denied Ian's words.

"If that were the case, then there would be no need for him to set up such a virtual space deep within Chaldea, right?"

"Wouldn't it be better to just set up something similar right where you just met?"

"Besides...what you encountered were clearly memories related to Ophelia, right? I don't think Marisbury could do that."

"what are you guys saying?"

Scathach poked her head between Ian and BB.

She completely didn't understand what the two people had just mentioned.

"Who is Marisbury, and why is this matter suddenly related to this name?"
