Diamond semiconductors were way too cheaty.

“Then can’t we make parts of diamond semiconductors from carbon?”

Miina was taken aback by the suspiciously conspiratorial tone of these words.

“If we could make diamond semiconductors, there would be a demand for billions of dollars all over Japan. As expected of Kiriha, you have a different perspective.”

“If that happens, Japan will be the first country in the world to have 6G, following 5G. This will change the global balance of power in the IT field.”

“Maria-chan is right. If 6G spreads to Japan, we can export to Europe, the U.S., and PAU, and the demand for semiconductors will be almost unlimited♪”

“What are semiconductors?”

“Semiconductors are components that store and release electricity and are essential for controlling all kinds of electronic devices.”

“What about 6G?”

“Let’s see~~……Sayuri-chan baton pass♪”

“Leave it to me.”

Director Sayuri gave a brisk explanation with an expression three times more dignified than that of an active teacher.

“5G and 6G are communication standards. At the beginning of the 21st century, computers around the world took a lot of time to download data. But in the 2020s, with the spread of 5G, download times will be reduced to zero.”

“Huh? But now devices have download times, don’t they?”

While downloading an app, I kept seeing the percentage display over and over as the download bar accumulated.

“You’re right. In the 2030s, with the advent of XR devices that send electrical signals directly to the visual field of the brain to show us AR, MR, and VR, mankind will once again be plagued with download times. Because XR contains so much data.”

Director Sayuri grinned after giving a nudge to the device worn behind her ear.

“However, the efficiency of diamond semiconductors is 50,000 times greater than that of today’s mainstream silicon semiconductors.”

“50,000!? That’s more inflated than the fighting power of a shonen battle manga! Even Super Sai*an 3 is 400 times its original fighting power!”

“It can’t be helped because it’s true. The problem, however, is the diamonds that make up the parts. With the current technology, it is not possible to mass-produce artificial diamond parts.”

“But if I mass-produce diamond parts with my [Rebuilding] and distribute them to domestic electronics and semiconductor manufacturers, Japan will be the only country in the world capable of mass-producing diamond semiconductors.”

“Mhm. Let’s support those manufacturers who cannot produce semiconductors individually with taxpayer money from the national government.”

“The electronics industry will be fine now. Now it’s up to the automakers to get everyone in Japan to buy a new car, right? What’s next after hydrogen-engine cars and electric cars, which are the mainstream now?”

“Hmm, if we had diamond semiconductors, we could dramatically reduce the size and improve the performance of automatic driving systems. However, even if all the semiconductor factories in Japan were to operate at full capacity, they would not be able to meet the demand for both devices and automobiles. Even if we build a new semiconductor factory now, it won’t be ready in time.”

“Wait.”

Kiriha stroked her lips and then adopted a somber expression for three seconds.

“……As self-driving cars become more popular, what is required of cars is not so much ease of driving as fuel problems and cruising range. Director Sayuri, I saw a news report last year that Tomita Motors had developed a new all-solid-state battery that can run for 10,000 kilometers in half the time it takes to recharge a conventional battery.”

“Let’s find out.”

Director Sayuri’s eyes darted around the multiple MR screens as she quickly navigated through them.

“Apparently, there is no prospect for mass production due to cost issues. The advantage of all-solid-state batteries was that they did not use rare metals, but the new all-solid-state batteries are said to use rare metals such as cobalt and manganese. No matter how good the performance is, consumers will not buy them if they see the price. Now they are focusing on developing sodium-ion batteries that use sodium, which can be extracted inexhaustibly from seawater. Hm? Cobalt and manganese?”

At that moment, Director Sayuri’s gaze and mine met with a snap.

“Huh?”

When I turned my head, all eyes were on me alone, even Maya was looking up at me.

“Ah, I can just apport from the bottom of the ocean?”

Getting the idea, I clapped my hands.

“Somehow it was solved quite easily♪”

“Mostly thanks to Kiriha and the others…….”

“Ooh? Honey-chan, did you feel left out? Don’t feel down, Shisae won’t make fun of silly Honey-chan, okay?”

“No, it’s just that I’m disappointed that I lost in the brain work.”

“Don’t be like that, Honey-chan, even Shisae is a lady full of intelligence!”

“You’re just an old man who calls herself a lady, hey stop it, don’t hit me silently, Maya, don’t kick me in the shin, and Maria, don’t kick me too, isn’t Maria on my side?”

“No, that was Honey-san’s fault, but I made my own decision.”

“Kuhh, this is the girls’ team Kiriha was talking about! I’ll oppose polygamy from now on!”

“Eh…? Honey doesn’t want to live a double bed life with me and Maria?”

She rolled her eyes and asked, and my head swelled with R-rated fantasies for 3,600 seconds a second.

“Y-you cowaaaard!”

“? Kiriha, why is Honey sitting like in the gym class?”

“I wonder why? Maya, make Honey stand up.”

“Un. Honey, don’t sit on the floor. Stand up and talk to us.”

“Guuh, do you enjoy bullying me so much!?”

“Yes.”

The answer was immediate. I wanted to stray from the right path. If I were an adult, I would probably want to have a drink.

Then, Maria quickly picked up Maya.

“Maya-san, don’t bother Honey-san, because right now he is battling his inner evil spirit.”

“Is Honey become a bad boy?”

“Yes, mostly in the lower half of his body.”

“It’s even more painful when you say it to each other with no expression on your face, so stop it!”

Maria and Maya, our expressionless sisters, were still emotionless and expressionless, tilting their heads curiously.
