''Before I explain........Shitenji-san, Marion-san, can you approach me for a moment?''

"What?

　For some reason, Mizuho and Marion approached Yuto's words with a blush on their cheeks.

''Oh, no, you don't have to get so close...''

"!

　Marion and Mizuho approached Masato normally at first, but when Marion took a step forward, Mizuho took a step forward, and when Mizuho took a step forward, Marion took a step forward, and then Marion took a step forward, and then Marion took a step forward, so the two of them ended up approaching Masato for the most part.

''Marion, what are you doing........''

Even Mizuho-san....

Well, let's get on with it, shall we?　You can feel it now, can't you?　My spiritual power....

I've been reading through the paperwork........

'Oh, yes. Certainly ... and ... this is an awful lot ...

I can barely even control it.

"...What does this have to do with enemy coordination?

'Yeah, the enemy's spiritual fog but you said the two of you didn't feel controlled at all, right?　I don't think it's like this quality of my spiritual power but isn't there some resemblance?

''Ah, indeed, Yuto-san!　It's much thinner than this... but I feel like it's similar in this uncontrolled, drifting feeling!

　Yuto nodded after hearing Marion's impressions.

''Then look at the way this spiritual power spreads.

　Mizuho circles around the 3 meter perimeter of Yuto.

'A circle?　It's spreading to... yeah?　Is this ... spherical?

　Yuto nodded again.

''That's right. I don't think everyone cares about it because when you give out your spiritual power, of course, you complete the jutsu while controlling it at the same time, but if you spread your spiritual power without controlling it....it's like this. My idiosyncratic constitution is an exception, so it's a bit different, but essentially when you practice this, depending on the amount of spiritual power you have, the range you drift in will expand as well.　Can you do that, Marion?

Yes?　Well I'll try!　Let's see.......something like this?　I've never done it before, so I'm not used to it, but...

　Then.........Mizuho and Yuto begin to feel spiritual power drifting from Marion.

''Ah!　It's like that!　It's a bit thicker in Marion... but this uncontrolled, drifting feeling...

''Yeah ... Marion-san isn't giving out much spiritual power right now, is she?　So I guess the spread is about the same as this room.　 Ah, Marion-san, that's enough.

　Marion nodded and stopped activating her spiritual power and turned her head to look at Yuto.

''Yuto-san, now the magic-based enemy summoner is controlling a large number of demons from a distance by increasing his sensing ability in this spiritual power fog, right?　But.........then.......the enemy summoner will continue to take damage, albeit it's a small amount, as long as they continue to use their magic power to sense the summoning demon. Will the summoner's lifeline of concentration, the summoner's lifeline, hold then...?

　What Marion said was a valid question. Mizuho felt that too.

''Yeah........I don't think that's the case either.... Probably, these enemies are the ones who made it possible. Because otherwise, it's hard to explain the events that happened. Certainly, it's not yet in the realm of possibility. But I think it's not unlikely. So I think it's worth taking this as a premise for the enemy to work on.

　Yuto's opinion reminded Mizuho and Marion of the enemy's cooperation so far. Certainly, they both thought that it was worth putting this possibility on the line now.

''Alright, Du Du Yuto.

　When Mizuho prompted him, Yuto nodded.

''Yeah, first of all, you let me know how the uncontrolled spiritual power spread earlier, and I'll use this.''

'What?　What does that mean...

'Well, it's easy to say, but the enemy's spiritual power is spread out in a sphere. If the assumptions of the enemy's method of coordination are correct, then the enemy is definitely including us and the enemy summoner within the scope of this unfolding spiritual power.

　Mizuho and Marion were delighted by Yuto's story.

''So there's an enemy summoner among them!　That should narrow down the enemy summoner's location considerably!　So, how do you determine where the enemy summoner is?

　Mizuho asked enthusiastically, but Yuto shook his head.

''No, I won't be looking for enemy summoners, okay?''

What? What?

　Both Mizuho and Marion look dumbfounded at Yuto's words.

''Wha-what do you mean!　Du Du Yuto!　Then what are you talking about earlier!

　Yuto quieted the angry Mizuho to a so-so level.

''My plan is aimed at...the psychic enemy abilities.

"!

''Honestly, even if we can narrow down the location of this enemy summoner, it's impossible to completely identify the location. I think the area where the spiritual power is drifting is quite large. Well, I think it's probably the farthest away from us in the range of spiritual power deployment. But it's still pretty indeterminate.

　Yuto continued his story.

''But here, if we can check the three points on the edge of the spherically spreading spiritual power, we can figure out the location of the enemy abilities that are emitting this spiritual power. So, we'll first strike this spiritual force-based enemy ability. That way, the freedom of this pesky enemy summoner's summoning demon of unknown origin will be much narrower. I think this will be a huge deal for us as guards.

'It's... ah!　I see!

　Marion's eyes widened and she raised her voice.

'What do you mean?'

　Mizuho didn't get the point from Yuto's explanation right now.



'It's true!　That's great!　Du Du Yujin!

　However, Yuto replied a bit awkwardly to the praise from the two of them.

'Yeah ... that's ... exactly!　I want to say......... To tell you the truth, that calculation is so difficult that I can't solve it myself...

'What?　Hey!　That doesn't make any sense!　I've lost my compliments.

　Mizuho is disappointed as she puts herself on the shelf.

''Haha........''

'Ta, sure ... that calculation is a three-way quadratic simultaneous equation ... so it's not easy ... if you're going to give us a quick answer on the spot. It's a bit........for us.

'You're not laughing at me!　Then what are you going to do, Du Du Yuto!

'Yeah, so ... look for three points at the same elevation.

...What's that?

'Oh!　Yuto, you're so smart!　And then.....

'Yes!　Then we can make it into a simple circle calculation.

　

''Du Du Yuto!　Just explain everything to me already!

'Uh, yeah, okay. First of all, my guess is that the enemy's spirit-powered summoner is probably ... up in the air.

"What?

''That's because the mountains are in the way of the terrain for this spiritual power to drift around universally. If there are too many obstructions between them, the spread of spiritual power will be distorted. For example, earlier, you confirmed that the spiritual power spreads spherically, but anything in between that me...

　Yuto said, and lifted a shelf in the room and brought it to the center of the room. He then positioned himself behind it, looking from Mizuho and the others.

''I think my spiritual power is having a harder time reaching that side right now.

Oh!

Oh, it's true. It's a little harder to feel!

'Yeah, the spiritual power doesn't penetrate 100% of the shielding. I'm sure everyone felt it for some reason too. And I think it's even more so when you're just a thin spiritual force in the air. With that in mind, I don't think they'll ever be at the same height as us because of the enemy's coordination. It's just too inefficient. We're surrounded by mountains big and small, so there's a lot of big shields around us...

　Furthermore, Yuto continues.

Take it. That way, that central point of....

　Here, Marion nodded vigorously. Finally, even Mizuho, who had caught up with her understanding, let out a wry smile.

''The enemy is right above it!

　Yuto also returned with a strong nod.

''But there's a prerequisite for this. First of all, there is a condition that the enemy's spiritual ability will not move from that location. The enemy will likely try to optimize the location of us and the enemy summoner, depending on the battle situation. That's why it's important that we don't move from the location of the enemy's attack.

I see...

''Yeah, so I want you two to hold your ground even if the enemy's attack pressure increases. I'll be able to find three points in the break in the drifting spiritual power to figure out the enemy in the meantime.

　After finishing Yuto's explanation, the three of them looked at each other. They nodded at each other silently.
　Then, Mizuho clenched her right fist in front of her chest with her left hand, with a face full of life.

''Enough about the details. So that's where I'll be able to unleash my big move on the enemy.......

　Thus, the plan was decided........Yuto, Mizuho and Marion were to wait for the enemy to attack.
　This time, instead of adapting to the enemy's raids, they wanted to use the enemy to take advantage of the raids.......
