Istor Academy of Magic, Magical Sciences Special Research Building.
　It is the highest research institute of the magical kingdom of Solstice, where the magical research factions including the Saint Germain faction gather.
　It is a research facility where students with excellent grades are gathered to research various magic and magic potions.
　This facility is connected to the Solstice Magic Kingdom Military Special Research Institute in the royal capital, and is especially active in analyzing the ingredients of medicinal herbs.
　The development of magic had been stalled due to the lack of progress in deciphering magic letters, but recently, with the announcement of research by the Saint Germain school, things have started to get back on track and it is finally possible to decipher magic formulas, but there is still a long way to go before we can fully understand them.
　However, there was one person who stood out from the rest of those who were working on it.
　He was Croisus Van Solstair.

　He is a genius who has always been at the top of the academy with a brain that overwhelms other students' grades. At one time, he was a unique mage who was called by two names, "the darling of magic.
　However, recently, he has become a troublemaker who is also called "the one who calls for disaster" by those close to him, and he is also an oddball who annoys the lecturer's camp.
　He is currently administering a drug to a rat-like creature called a ramotte to see its effects.
　Inside the glass case, the ramotte is rampaging wildly. It is about to break the case, but at the same time, the body of the ramotte is beginning to break down in a cruel manner.

"Well?　Mr. Croisus. What do you know?
"Selina ......, this is a dangerous potion. It shouldn't be allowed to exist.

　Croisus looked unusually stern.
　The look in his eyes was one of astonishment and contempt.

'Is it really that dangerous?　It seems like Lamotte is on a rampage... ...ugh!
"This potion uplifts the spirit and strengthens the body at the same time. There are similar potions that do just this, but the problem is that they force the body to draw on its own nutrient reserves and heal wounds with an uncanny ability to regenerate.
It sounds like a lot of good stuff, but what's so dangerous about it?
It is highly addictive and once you use it, you won't be able to stop. Moreover, it strengthens the body to the limit, so if you attack, your body will be destroyed, and then your body will be repaired with a powerful regenerative ability. ...... A severe addict will die quickly.

　This is the same potion that killed a Sumptroll three days ago.
　It is a kind of drug that is more dangerous than you think.
　It is a kind of drug that is more dangerous than you can imagine. It makes you feel good, but it also robs you of your calm judgment. At the same time, it brings out your violent instincts, and your behavior becomes unusually belligerent.
　If you are violent, you will naturally get hurt, and your injuries will be healed with an extraordinary regenerative power.
　And because of their powerful dependence on this potion, they will not be able to give it up and will continue to use it.
　As a result, by repeating this series of actions, the user will gradually become less and less human. Eventually, the user will turn into a demon like a Sumptroll. 　

The person who created ...... is a demon. I don't know why they made it, a potion that shouldn't even be allowed to exist.
"Hey ......, what if?　If this potion ever gets out into the world, ......
"If this potion gets out to the public, it could cause a mass exodus of demons from inside humans. ...... This is dangerous.
It's not dangerous. ...... It's a potion that brings disaster!　Who the hell gives a ......
Well?　But what do you think would happen if we gave this potion to the condemned and sent them to the front?
What?　Well, that's ......

　Most of the prisoners on death row are enslaved and have a "servitude collar" around their necks.
　If you strengthen the bodies of these condemned prisoners and send them to the front lines of the battlefield, you will be able to deal a great blow to the enemy.
　Moreover, they have a high regenerative capacity, and if left alone, they will continue to fight until they destroy themselves. There is no force more fearsome to a hostile nation than this.

It is a narcotic that strengthens the body and inhibits mental suppression. ...... In addition, there is a mysterious substance that I do not know what it is made from. It's supposed to promote physical transformation and powerful regenerative abilities. It's clearly military grade. If it's out there on the streets, it's ......
I'm afraid of terrorism ....... I don't know when people in the city are going to go crazy. ......
Sao Paulo Ahaea, you were probably experimented on. And ruined. Or in this case, self-destruction?
I'm a Sumptroll. You're royalty, after all.　You're royalty, you should know your name.
I'm not interested. I'm the second son. I'm not the heir to the throne. Besides, he's already dead, so there's no need to remember him.

　Croesus doesn't remember things that don't interest him.
　If he had to remember a name, it would only be someone who excelled in a particular field, or a great person in history.
　He can barely remember the names of his friends, but even then he sometimes makes mistakes. For this reason, I could never remember the names of people I had no connection with, much less dead people.
　In any case, I am a slow-paced person.

"My brother said that this is probably a verification experiment ...... aimed at what country?
It's not this country?　It's not this country?　Don't you think it was aimed at royalty?
I'm sure you'll be able to figure out the best way to get rid of it. Solistea is a small country, so it's easy to get your foot in the door to sell it.
"Is that so?　But if it's this effective, it could be useful depending on how you use it.
As long as it doesn't turn into a demon. The dependency is so strong that the danger is immeasurable. You never know when it might turn into a demon and attack your people. This is going to be important. ......



　The Magical Kingdom of Solistair is divided into the Guard and the Military, each with its own intelligence division.
　The guards have their own intelligence network for the safety of the country, while the military is divided into intelligence agencies for other countries. However, they are connected at the upper levels and have a system in place to facilitate security activities by exchanging useful information with each other.
　Depending on the content of the information, the Guard can request the military to mobilize, and conversely, the military can order the Guard to maintain public order. This kind of cooperation is especially important in times of crisis, as it requires speed.
　In fact, when the Duke of Delsacis crushed the [Hydra], the military and the guards conducted mutual maneuvers and laid siege to each other, so it can be assumed that there is no turf war within the jurisdiction.
　The only group that has yet to cooperate is the mages.

"Let's put it in a report for now. The higher-ups will make the rest of the decisions, and we'll continue as usual at .......
"Business as usual?　The same old explosions, toxic fumes, and temporary psychotic breakdowns?
...... No, just a little ...... deciphering and refining of the magic formula.
That's better. If you cause any more trouble, all the teachers will get a pit in their stomachs from the stress.
Terrible. ....... Technological progress is impossible without failure, and you're trying to prevent it?
"In your case, Croisus, there are too many victims of that failure. It's a wonder no one has died.
We do have ...... safeguards and inspections in place.

　It is a problem that no matter how many inspections and safety measures are taken, they have no effect at all.
　For some reason, when Croisus failed in his experiments, the damage would spread from unexpected places.
　No matter how many magical barriers he puts up or how rapidly he ventilates, the result is that his actions turn bad in other ways.
　For example, let's say that during an experiment, a poisonous gas of an unidentifiable color is produced, and in order to release the gas, magic is used to ventilate the area.
　However, the gas is heavier than air, and the ventilation releases the gas to the outside, resulting in a victim. That victim was Makarov, who is not here now.
　Yesterday, when we were improving the [breast implants], toxic gas was generated. When he let the gas escape, he fell victim to it.
　Now Makarov was too embarrassed to leave the dormitory because of his enlarged breasts.
　Through the door, I heard that Makarov's breasts are gradually returning to normal, but they are still big enough to be seen.

...... I'm not doing this intentionally, though.
If you do it intentionally, Makarov will kill you.　All of the affected boys are all in bed in shock, and only the girls are happy.
Only the girls were happy. - Happy because of a temporary effect?　I think it's just a fleeting dream. ....... If we can somehow sustain the effect, we can improve sales. My research is not going well. ...... It's worth doing.
But first, apologize to the boys. They're having nightmares.
"Hmm, that turned out to be quite interesting. Now let's try vaporizing it and selling it.
No remorse: ....... You'll seriously get yourself killed.

　For Croisus, failure was also success, and he was a researcher at heart who was happy to see meaningful results.
　Perhaps those who are called geniuses are somehow out of touch with the common sense of humanity.

Selina, please submit these results to the faculty office. I'll go tell your brother about it.
...... From there, the information goes to the Duke of Delsacis and then to the royal family. In a way, he's a faster communicator than the lecturers, isn't he?
There are only researchers here, you know. If you don't tell them, they'll try to create this [Devil's Pill] on their own, and if you're not careful, they'll start researching it in secret.
I'm not sure what to do, but I'm going to do it. Okay, I'll leave the submissions to you.
Thank you. As soon as we're done here, I'll go tell your brother.
Okay.

　Selina grabbed her clipboard and walked out of the lab.

Now, ......, where will this potion spread? At any rate, there will undoubtedly be casualties. ...... I wonder what's going on.

　I'm not sure what to make of that.
　It's a good idea to keep an eye out for any kind of incidents involving magic potion use. He was always on the lookout for incidents involving magic potions and the like, and he had a hunch that things were about to get really nasty.
　Seeing his profile, all the girls around him blushed, and all the boys went crazy with jealousy.

　I'm not sure what to say.

　After cleaning up, Croisus made a rare visit to the Tactical Research Building, where many Weaslerites were expected to be, but ...... unfortunately there was no sign of Zveit.
　I also went to the main library to see if I could find him, but I couldn't find him there either.

Where the heck is ...... my brother .........?

　Even though his level is a little higher, Croisus has no strength.
　No, to be precise, his stamina had only increased slightly.
　In the event that you've got a lot of time, you'll be able to take a look at a few of the best ways to get the most out of your time. And he was using the [Potion] just to make the pain go away.
　In appearance, he looks like a businessman who drinks nutritional drinks with gusto. Croisus, who usually leads a reclusive life, was physically inferior to everyone else. It seemed like a waste of a magic potion.
　Perhaps it had become too much of a hassle, Croisus decided to return to his dormitory. But what he saw there was .......

・・・・・・・・・・
You're late. Where the hell have you been?


Hey, man. Long time no see.

　Tsveit and Eromura were waiting for Croisus in front of the dormitory.
　Due to miscommunication, miscommunication, and misreading, Croisus' actions ended in vain.
　When you do something you don't normally do, you somehow fail. This was the first time Croisus had experienced this.

"Was it your brother and ...... Erodyceki?　Why are you in the dorm ......?
I'm not!　At least call me Enotozaki!
No, I was thinking of going to your room to talk to you once in a while, but come to think of it, it's possible that your dorm room is locked. So I waited here.
How long have you been ...... here?
Since when?　Before that, you were in the library.

The library is the common name for the Great Library. In other words, if Croisus had gone to the library from the beginning, he wouldn't have had to expend so much energy.
　It was a misunderstanding caused by the fact that both of them were doing something they did not normally do.

If you're in the dormitory, why don't you just go to your room? ....... Why here?
No, you usually lock your door.
I don't lock my room, you know.　I don't lock my room, because it's broken and it's a waste of time to lock it when I have to carry the materials out. Just leave it.
What would you do if you got robbed? ......
Comrade. Your brother is very sloppy.
It's okay. It's not every day that someone enters my room. ...... Oh?

　When Croisus was about to open the door, he heard what sounded like singing coming from inside.

I'm not sure if you've heard of it or not, but I have. Clean the room............
"What kind of song is that, ・・・・・?
"I hope you like it, Croisus..." "And .........
""・・・・・・・・・・・"

　There was a cold wind blowing.

"Yee Ling, you're cleaning my room again, aren't you? I appreciate it, but ...... I can't keep track of where everything is. It's a problem.
"You're cleaning my room out of the goodness of people's hearts, how dare you!　You rear-end bastard!
I do appreciate it, though.　However, aside from magic potions and the like, I don't know where the things I collect as a hobby have disappeared to. Just looking for them makes my room a mess.
"Clean up your own mess!　Don't leave it to others!
And she's a girl!　Not many girls are this caring. I envy you, d*mn it!
Well, there's no point in staying here, so let's go into the room. You're in the way of traffic and ...... what?

　I turned the doorknob, but for some reason the door wouldn't open.
　Croisus gave him a quizzical look, but continued to twist the doorknob several times.

"Something's wrong. The door won't open.
It's locked from the inside, isn't it?
Wait, Comrade!　Didn't you say the lock was broken?
Can you lock the door from the inside, or what about ......, Croesus?
It's the same from the inside. It was completely broken, so there was no way it could be locked. ....... Hmm, very interesting.

　---Oh, my God!
"What the hell -----?
What the hell?

　Suddenly, the roar of a beast and the scream of a maiden echoed.
　You can't open the door, but it's as hard as if it's made of steel.

　---Zzzzzzz!　Zulli...... Bisha.......

　I'm not sure if this is a good idea or not, but it's a good idea.
　It's not the kind of sound you can hear in a room.

I've never heard of it. ...... Is this the kind of weirdness you hear about? I've never heard of it. ......
What the hell is going on in there?　I've never heard of this phenomenon before.
I've never heard of a beast with big tits!　How far are you jealous ......?
I'm not sure what to do.
"There's an emergency!



　--bro-ro-ro-ro-ro-ro.
　--chirorin, chirorin.

　The sound of a motorcycle engine coming out of nowhere and a sound effect that sounds like something revealing a shiny object.

"Wahahahahahahahahaha!
"Yo-ho-ho-ho!
"・・・・・・・・　

　And the sound of laughter.

　---Jalalalalala!　Boop! The sound of a fire being ignited by something like a chain.
　---Bogh!　Thwack! (The sound of a blunt object being struck and pierced with a sharp object)
　---zap!　Boom! (the sound of slicing with a sword and freezing)
　---Zuggaaaaaaaaaan!　Buzz, buzz, buzz! (The sound of something heavy being slammed and torn apart after being swung around)
　---Pakey ------ ----n! (sound like something shattering)

"Goa......aa......aa......

　And the silence returns.

""・・・・・・・・・・・・"

　A strange silence ensues, and I don't know what to say.

"Thank you for everything. Thank you for everything, Skeleton Four.
"'Skeleton Four'?　Always!　You're always helping me?

　Behind a single door, something incredible was happening. In front of the room, the three of them stared blankly at the door for a while, unable to think straight.
　By the time they realized it, the sun was setting and the sky was turning red.

The sky was turning red.　We had lost consciousness. It's ...... dusk!
You've been here for over ...... three hours?
I've been here for over three hours!　Copyright, copyright, copyright, copyright .......

　There is an ordinary door in front of you. However, the distance of the door seemed far away to the three of them.
　The three of them were hesitant to enter the room where the abnormal situation had occurred.
　If they stepped into the room, they might find themselves in an unknown space where they could not even guarantee their lives.
　Thinking of this, they could not enter the room carelessly.
　Right in front of the three of them, the door opened quietly. The person who appeared was Yee Lin, a beastman with drooping dog ears.

"Oh, it's you, Croisus! You can't do that.　You have to clean up your room.
I'm going to ask you a question. What has been going on in this room?
Hmm?　Cleaning up your room?　I'm not sure if it's a good thing or not.
No, more importantly, what is Skeleton Four? ......
Skeleton Four?　What's that?　A new kind of monster?

　The three of them looked at each other in confusion.
　No matter how you look at it, Yi Lin doesn't seem to be cheating or lying. However, from what they heard outside the door, she did know about Skeleton Four.

You don't think that when he walked out the door, his memory was ......?
That's ridiculous. ...... That would mean there's another providence at work in this room!
I think I'm going to get sued for copyright ...... all sorts of things. It's bad in another way.

　While the three of them were discussing with serious expressions, Yee Lin was tilting her head curiously.

Yee Lin ...... checks again. Did anything happen while you were cleaning the room?
"Hmmm, ...... I think something great happened, but I think ...... it was just my imagination.
"You still don't remember, do you ....... What's going on in your room?
I don't know. I'm not sure what's going on, but even if you do uncover the truth, you'll lose your memory. I don't know. ...... There's also the case of Carostee, so I'm not sure if that's the case ......?
This is the only room that's magical. This is the only room in the house that is not a fantasy .......
I'm not sure what to make of it, but I'm sure it's a good idea.　It's a lot of work.
"In a different way.

　Putting off solving the riddle for now, the three of them entered Croisus' room with trepidation.
　The room was so neat and tidy that they could tell it had just been cleaned, and there was not a speck of dust in sight.
　While the three of them were nervously examining the room, Yee Lin said, "I'm hungry, so I'm going to go eat," and headed for the dining room. It seems that she was cleaning the room without eating.
　The two anti-rearers looked at Croisus with envy and jealousy. It's ugly.

There's nothing funny about .......
Yeah, there's nothing wrong with ......, but you can never be too careful.


Hmm, if nothing happens, it's just as well, and I should tell you about that potion.
"Yeah, ....... That's what I was going for in the first place. ......
Are you sure you're okay?　I'm worried. ......

　For the next hour, Croisus and Tveit thought about the potion report and the potion maker's intentions, and wrote down as many possible predictions on paper as they could think of.
I don't know what the [Devil's Pill] was made for, but by predicting its effects and the intentions of its makers, we can make our next move.
　This is just a guess. It may end up being a temporary measure, but it is better than nothing. Informing the academy of the anticipated situation could be a preventive measure.
　But at this moment, the three of them forgot. This room is a Danger Room that leads to the other world. .......
　And Elomura's fears came true.

"d*mn it!　What the hell is this monster?　And what is this vast world ......?
"It's not a creature, it's a machine!　It's a biological machine!
That's not good ....... If we continue like this, our magic power will ...... run out of steam and we'll end up like them.

　---I'm not sure what to do.

"Croisus, Croisus, Croisus!

　I seem to have gotten caught up in a strange world.

"...... Croisus' guy got eaten. ......
I'm not sure where I've seen that before.
"Comrade!

　---Onnaaaaaaaaaaaaaaaaaaaaaaa .......

"Even if you're a monster, you still love women that much, don't you, Eromura? -------?

　---Tozendaaaaaaaa .......

"You answered?　I'm not sure what to say... ......

　It was a very bad situation.
　In front of Croisus's room, there was a loud explosion from the inside and the sound of a huge object fighting a loud battle, and the students passing through the corridor heard it and ran off with pale expressions.
　Sometimes you can hear through the door, 'Shoot it out, show me you can stop it! I'm not doing this for fun! I'm not doing this for fun!" or "I'll finish you off with this! and "Let there be light! and "Be the light!
　It's a mystery where it really leads.

"Hey, not again. Why don't you take a peek?
"No!　I don't want to be a part of this!　If you're interested, you take a peek!
I'm not kidding. Don't make me peek in that creepy room.

　No one dared to peek inside, and they hurriedly evacuated the place.
　It had already become a tacit understanding that this was a place that should not be entered, and it had already spread throughout the school.

　The next day, the three of them collapsed together in the middle of the room.
　For some reason, they had a strangely refreshing morning and felt as if they had been reborn. And it seems that they had been slightly upgraded.
　This is the Danger Room. A dimensional room that connects to the other world.
　At the end of the day, the reason why such a room was created was never found out.
　There have been rare exceptions, but the victims themselves have forgotten what happened to them.

　... ... ... ... ... ... ...

　We go back in time about three hours.
　In the academy, there is a kind of circle activity that the students do independently.
　In particular, there are many sports clubs, and "placke", a sport that combines tennis and target shooting, is particularly popular. Especially for girls.
　A board with a score written on it is placed outside the team's position on the court, and the players compete for points by hitting the ball with a racket and shooting at the target. Players can change the location of the board, which is a target with a score of 1 to 10, at will, and compete with each other for points.
　The players are called "Gardner" and "Blader", and their roles are to protect the board from attacks by the opponent and to aim at the board.
　Basically, it was a doubles game. Of course, recently we have started to play singles, and each school has been holding official games.
　Aside from that, there is also a changing room, which is a natural part of such circle activities.
　In the changing rooms, students who had worked up a sweat at Plakke would take a shower and change their sweat-stained underwear.
　From time to time, there are boys who break into the school to peep in, but those who do so will be punished severely.
　Fortunately, no one was foolish enough to do so on this day.

I'm so tired, I wish I could use the ...... shower a little longer.
It's hard to have a set amount of time for each person to use it. Well, it's a magic tool, so it can't be helped.

　The shower can be used by attaching a magic tool to the water pipe to boil water, but this water heating magic tool can only boil water if the user puts magic power into it, and based on the amount of magic power put into it, it can only last for about 10 minutes.
　Moreover, once the water is boiling, it cannot be stopped, and detergent cannot be used to wash the body.
　It was a great invention, but the drawback was that it was not very convenient to use. For this reason, many students bathed after returning to the dormitory.

Can't we do something about the underwear?　It's not cute, and the colors are all the same. ...... It's plain.


"That's right. Maybe the fabric is bad, but it gets itchy when I sweat.
But only aristocrats can afford good underwear, you know?

　Women's underwear in this world barely resembles the shape of modern Earth, but it is simple and without any unnecessary decoration. There was no such thing as a size standard, and those who didn't fit were left feeling a bit unsatisfied.
　The fabric used for women's underwear was also moderately priced, and there were many clothing stores that collected used underwear.
　The collected women's underwear was mainly passed on to slave traders and female prisoners who had committed crimes. Not even a small piece of cloth is manufactured in such large quantities that it cannot be wasted.
　Prostitutes buy used clothes and underwear of the nobility at discount prices and lure men on the streets. Thanks to these discount stores, business is possible. 　
　However, the prices are a little beyond the reach of ordinary girls, and even if they could afford to buy such items, they would certainly be living in extreme poverty for a while. Prices of fabrics such as silk are too high for ordinary people.

"I wonder if there are any cute underwear for sale somewhere.
"Did you call ......?
What the hell?

　Before she knew it, a pink ninja was sitting on the table in front of her in her underwear.
　He was carrying a large wrapping cloth on his back. .......

"......, who are you?
...... Do you want some underwear?　A bra?　Or panties?
...... What are you doing in the locker room?　If you want to do business, you can do it on the street. ......
You can't sell ......... a girl's underwear on the street. They'll ...... report you. ......
So you broke into the locker room?
......... Yeah.

　I'm sure you'll be able to find something that will help you get through the day. And there is no way you can try them on.
　With this in mind, Anzu seems to have decided to sell them in the women's locker room. However, its sudden appearance brought nothing but confusion.
　However, Anzu, who has a fast-paced personality, does not care about such things. Without saying a word, she opened the wrapping cloth and began to unfold the product in front of the girls.
　The color of the girls' eyes gradually changed.
　This was because the women's underwear that Anne was selling was something unknown to them.
　They are brightly colored, lacy, and elegantly finished. Above all, they have the cuteness that these women are looking for. Some of them are even mature and extreme.
　In the eyes of the girls, it must be a work of art of the highest order.

There are a variety of sizes available at ....... The sooner the better. ......
Wait, we can't afford this kind of underwear.
Yeah, ...... I think only the aristocracy can afford this stuff. My allowance is ......
...... No problem. The materials are carefully selected so that they can be bought at a reasonable price. Do you want to ...... try it on?

　It was the devil's whisper to the girls.
　The underwear they are wearing right now is not very pretty, and is made without regard to size, and is intended for mass production. But there is something different about what we see before us.
　It seems to the girls to be a cursed piece of equipment with a magical glow.

It's the ......... pull up method. It's a great way to keep your body in line with ...... your pretty face.
"You can ...... try it on ........., right?
"......Yes.

　We all gasped. And then, instinctively, they knew.
　If I try on this underwear now, I'll feel inadequate in my existing underwear. .......
　I'm interested. However, we feel a sense of crisis that if we get that satisfying feeling, which is probably similar to a drug, we will only be able to use the underwear in front of us. Mainly financially, though.
　Nevertheless, teenage girls do not have the self-control to resist this temptation. No, in this case it's curiosity.

"Hey, can I try it on?　I'm interested in that ......, but I don't know if it will fit me. ......
"This is the one that fits you. Be orthodox and start with white .......
「「「「! 」」」」」

　While everyone is hesitant to take the first step, one girl takes the lead.
　Anzu took a quick glance at the girl's measurements and chose the perfect size for her.
　After all, this was a locker room. It was no problem to find out her size, because everyone was dressed like that.
　The girl took the underwear from Anne hesitantly.

The ...... bra is front-hook and is designed to correct your style.
I'll try it on at .......

　I'm sure you'll be pleased with the results.
　This is a great way to make sure you are getting the most out of your time with your family.

"What the heck ...... is this?

　It was truly a revolution. The fit was superb, it didn't slip off when we moved, and above all, it felt good on the skin.
　The girl was enveloped in an inexplicable sense of happiness at this supreme gem that seemed to embody the ideal they were seeking.


　The pure white underwear she wore was truly a holy sword that could kill a demon king. If I used this underwear, anything from other stores would be like a goblin's club. It was an overwhelmingly destructive feeling of satisfaction.

My research on ...... was complete. I'm using multiple fabrics in different parts of the body to solve that frustration. ......
"But, but ...... isn't it expensive for such a great product?
The more expensive fabrics are only used in some of the sensitive areas. ....... It feels good on the skin, and most importantly, it's not too diverse. ....... Others are more absorbent and stretchy. ...... I've tried everything.
"K, but ...... when the monthly ones come ......
There's also ...... sanitary products, okay?　If you add up the total amount, you get ...... and ...... and ...... and that's it .......
「「「「! 」」」」」

　She played the abacus and showed him the total amount.
　As soon as they saw the price, the eyes of the maidens changed instantly.
　The price was reasonable and reasonable.

Please sell it to me!　I'll pay you right now!　I'll pay you now! No, I'll spend all my money to buy something else!
.........

　The girl who tried on the dress immediately ran to her locker, took the money out of her purse and paid immediately. She also bought some other underwear, including sanitary products.
　This triggered a rush of maidens to the apricot shop, as if the floodgates had been breached.

"Wow, sell me some!　Sell me this blue one at ......!
"Oh, that's the one I was after!
I have to get my purse back to the dorm!
Please!　Lend me some money, I'm in a tight spot this month!
No, I'm buying that!
No, I'll buy it! ...... This time, only this room is for sale. ......... There's still some ...... for you to peruse.

　I'm not sure if you've heard of this, but I'm sure you've heard of it.
　It was the eyes of a hungry beast. That's how bad the women's underwear situation was in this world. It's just like Japan after the war. .......
　In the first place, most of the craftsmen who make clothes in this world are men, and there is no way they can make adjustments that only women can understand. This is why, although underwear is only available in the form of lingerie, it is rarely available in a form that satisfies women.
　On this day, in the changing rooms of Istor Academy of Magic, a women's underwear revolution took place.
　There will be no stopping it. After that day, sales of women's underwear in the clothing stores of the academy city slowed down, and eventually other craftsmen saw Anzu's underwear and felt a tremor.

　Afterwards, the girls who didn't have their wallets with them went back to their dormitories to get them, while the rest of the girls tried them on and looked blissfully happy with their perfection.
　Even if the fabric used is cheap, the skills of the [sewing emperor] create works of art.
　These works of art captivated the girls, and everyone in the locker room had their lusts aroused.
　When the girls returned to the dormitory, they kept her secret to gain an advantage over the other girls and bought a lot of underwear.
　From that day onwards, Anne's clientele gradually increased, and soon the students at the school began to wait for her to appear. Eventually, the faculty will join her.
　The unseen lingerie seller soon became an urban legend.

　A week later, the number of crimes committed by boys increases. It is commonly referred to as underwear stealing.
　Men who peek at each other naturally steal underwear in order to get the loot. What apricots sell becomes a spark for new crimes.
　As a result, many foolish boys are caught by the guards, and those who sneak into the girls' dormitory to steal underwear are half killed.
　A war broke out between the stupid boys and the girls who wanted to protect their underwear.

　The story takes place in Japan.

　The place is Japan on Earth.
　They move to an apartment in a rural area.
　The small room is lined with game consoles, and piles of manga books and bookshelves are blocking the sunlight.
　The laundry is stacked on top of each other, and the bags of snacks and plastic bottles left in a haphazard manner clearly indicate that this is the room of a recluse.
　In such a trashy room, a boy of high school age was enjoying playing a mobile game online.
　In the quiet room, the sound of buttons being operated flows quietly.

"...... Oh, is there a visitor?
Hi, Chemo, long time no see.

　There was no sign of the door being opened, but before I knew it, a woman in her twenties was inside the room.

Is that you, .......? What's wrong?
"What's wrong?" "What's not wrong? That world ...... is losing its dimensional balance, you know.　If we don't do something soon, the damage will come to us.
"...... dimensional balance?　Did you summon the hero again?
That's not quite right. It's just that the distortion of dimensional space is growing due to summonses, and singularities occur frequently. Each time it leads to a different world. ......


"Do you have any idea why?　I'm afraid that's all I have to say. ......
The location of the singularity is fixed. It's just that the otherworldly contact is randomly triggered. It's not good if we don't decide who the observer is. We're okay for now, but in another hundred years, there's a good chance it'll cause a dimensional fusion.
That's true. But we can't interfere with that now. Unless she's back.
You sent her back, didn't you?　She hasn't regenerated yet?　I don't want to risk annihilation.
I'll leave it to him. I'm sure he'll revive her soon, right?　That's why we sent in a player with a difficult personality.

　It's not like he's a boy, but his tone of voice is very mature, and he says things that don't seem real.
　If you were to listen to them from the side, they would sound like they were suffering from "Kitchen Sickness".
　However, their expressions were serious.

In the end, we'll have to wait for her to come back. ...... We can't let that happen. Can't we get a special dispensation?
It's the test world that happened. The problem is that the aftermath flowed back to us. Well, the Covenant's been broken.
Of course. If they keep the Covenant, we'll be very angry.
Well, I've given you some advice. "Don't be too hard on the humans.
I don't think those idiots are going to take my advice.　They think they're as good as us.
Yes, they do. But they'll learn that they can't go on like this forever. Not if she's back.
So you're sending him?　He's your friend, isn't he?
Well, if you're really mad at me, I'll punch you in the face. I'll give you anything you want.
He's ...... irresponsible, too, leaving all this trouble behind.
It's okay. It'll pass the time, right?　You can keep an eye on him for a while.
I don't blame you. ....... But can't we do something about the singularity?
Not right now. We can't interfere with each other, can we?　Let's just wait and see.

　We're discussing an important matter, but there's not much sense of urgency.

So, that's it?
The rest is personal. I'm going to spend a few days here.
Another host club?
Leave me alone!　Today is the day I'm going to make you fall in love with ATSUSHI!
...... You never learn. Well, not too much.

　Before the boy could finish, the woman's figure vanished in an instant.
　It was as if she had never existed in the first place. .......

Now, it's all up to you. Good luck, Xellos. ......

　Looking up into the void, the boy muttered and started playing the mobile game again.
　Once again, the sound of him pressing the buttons on his portable game console drifted through the apartment.
