　There's something I've been thinking about all these years. In the world I reincarnated in, military technology has made great strides. There are even things like power suits and space armies, so why don't we make them?
　Just in time for today, neither Alice nor Aikawa-san will be coming to the research building as their lectures are held outside the academy. I talk to Shingo, who is preparing a trick for Conn while feeding him tomatoes, with a serious expression on his face.

Shingo, I have something to discuss with you. It's very important.

　When I speak to him in an unusual manner, Shingo straightens his posture and urges me to continue.

'Shingo, I think I'm going to make an 'optical camouflage'

　When I said that, Shingo asked me why. It's not only that, but it's also that I need to report to the headmaster if the reason is too dangerous. You can justify the true reason right here and now, but will that really keep me from regretting my decision?
I'm sure there will come a time when I will regret tricking my best friend into creating optical camouflage by hiding the truth. I decided that in my heart, I looked Shingo squarely in the eye and clearly stated my purpose.

"I want to look in Alice's shower.

　The moment Shingo hears my words, he tries to say something with a surprised look on his face, but he restrains it with his hand. There's more to my words, I really need Shingo to hear that too.

'You know that there is a shower room here in my research building. And this is also the research building that Aikawa-san uses.

　I look at Shingo as he speaks, and it seems that he listens. I bring my tea to my mouth to calm down and continue talking.

If Aikawa-san were to use the shower, would you be able to wait quietly for him?　And you're thinking, "I need a peek. But if you only peek, you're afraid of being discovered, and that's where the optical camouflage comes in.
　If you refuse to help for ethical reasons after hearing all this, I don't blame you. But if you can, please keep this story to yourself, because I'm going to start working on it by myself.

　After speaking at once, I look at Shingo while putting the cup of tea back on the desk. There was the figure of his best friend with the face of a Han........no, a 'comrade'.

''Fuhi! Of course we're going to cooperate.



　With Shingo's powerful words, our "Optical Camouflage Development Project" was underway.






----Miki Arakawa's point of view


Emergency report.

　As I was compiling a report on my research in my room, the person in charge of security for Conju and Shuichi's subordinate, the person in charge of information who was investigating information on Conju's personal terminal and other information, sent me a communication. Did that girl do something again?　As I was thinking about this, the information officer began to explain.

'Since the other day, we have observed an extreme increase in the usage of Gongju-kun's personal terminal. We've determined the cause and found it in a protected folder, and we're transferring it to you.

　The file sent to my terminal was named "The Secret Project". I no longer had a bad feeling about it, but I checked the contents.

Optical Camouflage Development Project: The goal is to develop an optical camouflage that can be used by individuals. The minimum achievable capability is silent, waterproof and more than 30 minutes of operation. As an additional objective, we aim to mount it on a power suit for outdoor use.

　Is my son going to start a war with some country?　The same is true of the 8th generation plane she built the other day, and the AI-equipped work robot she was helping to create can only be considered a furious preparation for war if you think about it calmly. Aside from a large country like the United States of America, a small country could afford to let that one girl fall with ease. I instructed the two of them with the worst possible expectations in mind.

''I will discuss this matter with the higher-ups and my husband before making a decision. Until then, please keep it under surveillance only, if you provoke Gongju inappropriately, your lives will be in danger.

　After cutting off the communication with that, I immediately call up Shuichi's personal terminal and send a transmission.

"What is he trying to do?

　I forwarded the file to Shuichi, who was immediately connected, and when I consulted him, he looked puzzled and had his head in his hands. In the end, we concluded that she was ready, so there was no way she would immediately do something dangerous, and we decided to continue the strict monitoring.



　A few days later, I received an urgent message from the special team that was monitoring him.

'We have conducted a test run of the optical camouflage prototype that Gongju and his friend had built and it was a success. It responded to the infrared detector, but to the naked eye, it completely disappeared and then went completely invisible for the next twenty minutes.

Okay. Anything else to report?

　When I asked him that, it seemed that he had also made a few prototype reconnaissance models of small insect-type robots equipped with optical camouflage that could turn invisible for a few minutes. It's a problem, we can't protect them any longer if they are so clearly preparing for war. Who are they planning to declare war on?　Just as I am about to enter that poor nation's identification process, a heart-grabbing report comes in.

'It's urgent! Kouki-kun has decided to put the reconnaissance type into action in the academy. We've already started using it now.

　I didn't make it in time........I don't know what that kid is going to make the scouting type do, but the academy is going to be hell. I give instructions while biting down on the regret of why I didn't understand my child's feelings more.

'Please relay my son's appearance over here, once we know what we're doing, we can do something about it. Oh, and please ask the Self-Defense Force to be dispatched, and tell them to send their students to evacuate.

　The figure and voice of Kunki comes into my terminal.

''Roberta-sensei was the advisor of the swimming club, right?

'Huh, yes. I think it's the locker room at this time of day, and I can get in through the ventilation fan if you're the first one, Mr. Cockatoo.

　I can see him controlling the terminal as he says this. And.

We're in!

How's it going?　Can you see my tits?

Don't panic. They'll crush you if they see you. He's just a worm on the outside.

I found myself getting excited. What does this mean, isn't it a weapons test?　I'm confused and he's talking excitedly about 'Dr. Roberta's big one' and so on. No doubt, this is my stupid son and his friend who are seriously trying to master the act of voyeurism. I feel dizzy, but I send a message to the surveillance team.

'That's enough, please withdraw. Oh, and please give the self-defense forces a false alarm and notification.

　After cutting off the communication with that, I seriously wondered for a while whether I should be happy with my son's healthy growth or scold him for his peeping behavior.

　There's something I've been thinking about since last night, I don't understand why Mom said that, but I have to admit it as fact. To be honest, it's frustrating, but I don't remember any loss by listening to my mother's opinion, so I reluctantly talk to Shingo, who is preparing a trick while feeding Kon a banana with a serious look on his face.

'Shingo, I have something to discuss with you. It's very important.

When I speak to him in an unusual manner, Shingo also straightens his posture and urges me to continue.

'My mom found out about the peeps,'

'What?　Why not?

　I don't know!　I'd love to hear it. Last night we were eating dinner as usual when suddenly she said, 'Ko-chan, I understand you're interested, but no peeking. If Alice finds out, she'll reject you.　I told him with a smile, 'I'm sure'. Where did you get the information, I'm very scared.... I was honest with her, and she looked at me thoughtfully.

Huhhi, so what do you do with the finished optical camouflage?

You can install it in my power suit and then use it for Shingo's next research presentation.

　It's not like I'm going to be of any use to you even if I have a report on my research. I'll give it to my comrades generously and make sure that the next time something happens, we'll be able to cooperate smoothly.... When I was thinking somewhat calculatively, Shingo asked me to lower my voice, and


What are you going to do with that 'picture' of Dr. Roberta that you took?

　Of course it's going to be heavily protected and stored on the device!　When I say that.




　The face of my comrade was there, smiling and giving me a thumbs up.
