The kingdom of Azarel is a small country bordering the southeast corner of the Aragon Empire.

Known for its exceptional agriculture, Azarel is a valuable trading partner and ally of Aragon. As of right now, its borders with the demons are being breached.

If I were to make it sound more serious... well, the invaders this time are actually intelligent. It means that if they were to seize Azarel's military, they would also be able to own the heavy firepower we gave the Allies as well.

Just imagine succubi flying around with our magically engineered guns. It makes me cringe.

So, rightfully, we have the duty to wipe those things out.

As soon as we approach the border, I can see the desolate land beyond Azarel's walls. Although there isn't any apparent sign of battles, I can still smell the aura of death wafting over...

Okay, I actually just wanted to say that once.

Other than having nothing noteworthy, the lands of demons are largely similar to normal territories. Only the area surrounding the demon king's base is different. I know this from reading books, by the way.

''Hm... that's indeed a mess.''

As we poke our heads out from Sariel's back and observe the overall situation below, a clear picture of chaos emerges. Not just any chaos, mind you.

A depraved chaos.

Look, a border isn't just a slightly long line of walls separating this side and that side. It's a goddamn SCP-3000 over here, alright?

Behind those walls, buildings for accommodation, storage, pathways, etc., extend deeply into Azarel's land, which is seriously spacious. Cleaning up every nook and cranny of this border is inevitably going to be tedious.

Now, let's get back to the chaos part.

To the naked eye, it might seem as though everything is going as usual, but since our eyes aren't 'naked,' we can see most things that are not inherently visible from this position. These can be scenes from really far away or scenes hidden behind covers.

I'm not quite sure how to explain it, but there is this certain wave that allows us to shape the outline of things around us. It's like an omnipotent radar.

And what are those scenes, one might ask... sex, of course.

Whether it'd be succubi luring soldiers into obscure locations to milk their life force or incubi seducing officers with their unnatural charm...

Either way, I need to devise a quick plan for now.

''Let's quietly take care of the ones who are in the act first,'' I propose. ''Afterward, we can go through the entire border with my ability activated.''

This narrative has been purloined without the author's approval. Report any appearances on Amazon.

Then, I continue, ''Since those things dying off will cause chaos, I think some might try to escape as well. Anna, can you take care of those?''

''Mhm... it's a bit straining, still, but I think I can do it.''

Bearing a sweet smile akin to that of a flower blooming, the cat girl quietly deploys a thin barrier roughly surrounding the border.

''I'll count on you all. Good luck.''

As everybody nods at me, we swiftly begin the operation.

It starts with Sariel's polymorphing. As soon as she turns into a human, we lose our footing and fall down. Then, with each holding their own weapon, we disperse.

''Take these, Luna.''

''Oh... thank you.''

Since Luna has depleted a large portion of her energy to replace Eva for a while, I thought she might make good use of a few rifles. Seeing her smile silly like this, I guess it is the right move.

And so, I also take out my M16 and sprint off.

As I have discarded mana in favor of divine power, I think I can start using up all the mana bullets now. Especially, I have a ton of AP and explosive tips. The former is useful here.

Running between buildings, I simultaneously erase my presence while aiming precisely at the heads of the demons nearby. Even if they are behind covers, they will die.

With my senses, I can vividly hear the moment their skulls are pierced.

Taste the true power of wallhacks, you idiots.

Still, there is an unimaginable amount of enemies to handle, so I should hurry.

----------------------------------------

''Whew...''

Tossing the empty mag into my space storage, I finally rest my gun and gaze at the sky.

When we first arrived here, it was morning, but now stars have filled the sky. It does take a while, even with the seven of us running at full speed, but finally...

My party members return from their jobs one by one, looking a bit exhausted. It's understandable since they just had to sprint hundreds of kilometers while actively using their senses and abilities.

''How's your kill count?'' I casually ask.

Surprisingly, the numbers are quite equal. It seems each of us has managed to eliminate around two to three thousand enemies. Only Anna's number is marginally less than that. Otherwise, it's honestly a lot.

''Well... I think now is the important part.''

The fact that I used the heck out of my gun since morning is partly because I wanted to simply shoot, but the most important reason was to preserve my strength.

Covering the whole border of this length and size is really, really taxing, but since I got a fuck ton of power from Eva fucking me, it can only be done by me.

''Cover me, alright?''

As I quietly unbutton the lower half of my shirt, in the process revealing my elaborate heart crest, I receive reassuring gazes from my partners.

''Once we're done with this, I'll sit on your faces, alright?''

Oh, that does fire them up a lot.

Nevertheless, I begin to float in the air and release my aura to the surroundings. If I had to describe it, I would say the ability feels similar to a fog. Meticulously controlling the density of this 'fog' to be on just the right density, I advance forward.

If I concentrated it to the maximum degree, most would lose their minds within seconds, or even someone like Eva would be infatuated with my body. Yet, that is a story for another time.

Slowly, slowly, people begin to flock out on the streets, their gazes and attention solely on me.

They look like zombies. Creepy.

''Huh, what is this—''

A young officer, who seems confused at the sight, then promptly gets her throat clutched by Liana. Soon, under my future wife's immense pressure, her true appearance as a succubus emerges.

''Die.''

And so, this process is then repeated again, again, again, and again...

The sun rises above the horizon before coming down and rises another time before, once again, going down. At some point, I stop paying attention to the time altogether.

Fortunately, there are still my partners who will chat me up, feed me, and take care of me along the way.

Around a week passes, and we've finally finished rinsing the border.

''Hah...''

Collapsing onto the ground, I silently look up at the starry sky.

I'm exhausted. Really hungry. That kind of hungry. I need energy.

Still, I heard reinforcements have arrived, so this border will soon regain its functionality, I suppose.

And...

''Look at what we got.''

''Mhmp...!''

We have captured the succubus princess.
