When no replies returned after hearing what he had to say, Shirone lost his confidence and hurriedly added.
âOther than this method, various traps can be installed as well. For example, if you use keywordsâŚâ
Yiruki shook his head.
âNo, itâll be fine. Itâs not only good, but those are necessary elements.â
Nade agreed.
âYeah. This is quite subtle. Youâre using the presentation as a tool.â
As the structure was established, the three began to plan detailed operations.
âThe only problem is this. How do we present a ghost?â
The technical part was up to Nade.
He rose from the sofa and cast Lightning Shadow which created another Nade made up of electricity.
âWe can make a ghost shape like this. But no one will be deceived by an unmoving ghost. That is the part Iâm worried about.â
Yiruki nodded.
âWe can think from there. How can we make the afterimage move?â
âThis is what came to mind right now. Quickly linking together Lightning ShadowâŚâ
As Nade moved, the afterimage was taken in each frame of Nadeâs movement, giving the impression of walking.
âI see. So youâre saying we can use optical illusion to make it look real.â
âRight. However, magic has its limits. Moreover, I canât increase the number of individuals at my level.â
Shirone asked.
âWhat if we were to use a mechanical device?â
âEasier said than done. Even if we do make a device, there is a mountain pile of stuff to consider. The biggest problem is, what if people arenât fooled even after we implemented the movements? If we really want to make them believe, we need it to be responsive to external stimuli.â
Yiruki racked his brain for a while and said.
âHow about⌠Predicting peopleâs reactions ahead of time?â
âPredicting their reaction?â
âWe will adopt the Complex System Theory. We analyze the public's behavioral patterns and program them. Itâs a way to create the illusion that weâre actually getting feedback. Problem is thatâs itâs a huge amount of information. We need a medium and control system to deliver the information.â
âHmm. Transmitting information. There certainly are limits to my electric ability. Then⌠Ah!â
Nade turned to Shirone.
âPhoton Output! We have Shironeâs photon output!â
âAha! With photon outputâŚâ
Shirone thought there was a possibility. It was a magic he learned to take the Targeting exam, but in the magic society, the research on transmitting information through photon output was in full swing.
âNow itâs sorted then. Nade will create a hologram device. I will make the program that will go into the device, and it will be Shironeâs photon output that will send my program to the device. It probably requires a huge output, can you do it?â
âI have to. Itâs a one in a million opportunity.â
They finally saw a ray of light in the darkness. Nade was thrilled just to have hope for something he thought was impossible.
âWe can do it. We can protect our research group. Of course, assuming there will be no accidents.â
âThe academy will be in a fuss if we succeed, right?â
âMore than that, actually. I think the academy will be in an uproar. Iâll bet my money on that. Besides, I think itâll be so much fun. Kekeke. Iâm already looking forward to the teachersâ reactions.â
Yiruki and Nade turned to look at each other and gave an evil smirk. With the existence of the Supernatural Psychic Science Research Group on the line, an unprecedented event in the history of the magic academy was occur.

Shirone spent his time increasing the effectiveness of his photon output. The key was to increase the strength of the output while increasing the retention time. Weightless photons could not inflict any physical force, meaning it could not be used as attack magic. However, this time around, that characteristic turned out to be an advantage. This was because Shirone could go and train in any storage room in Estas.
Shirone put out his two hands. He concentrated and cast Photon Output.
As the beam of light started to create a circle on the wall, Shirone began to push himself.
If he couldnât hold out like this for 10 minutes, then there was no point in attempting to increase the output.
Although the level of difficulty exceeded that of Class 5, it was the same for Nadeâs hologram device and Yirukiâs Complex System Equation.
âI have to succeed. IâŚâ
Shirone clenched his teeth and held out.
After three minutes, he began to lose consciousness.
He was able to withstand a minute while casting a single photon output during the Speed Gun exam, so his current progress showed remarkable growth compared to then.
âHeuk! Heuk!â
The result of 10 days of training was a record of 3 minutes and 20 seconds.
Shirone had to increase it to 10 minutes within the next 20 days.
After measuring the new record, he always had to rest for 20 minutes because he was carrying out a training that could be life threatening if recovery was neglected.
Shirone was taking a break when he heard a noise from the warehouse beyond the wall. Nade seemed to have started welding.
When Shirone entered the store room next door to figure out the situation, he saw Nade buried in mechanical parts.
âYo, Shirone. Howâs the output time?â
âSo-so. I increased it by about 20 seconds. What about you?â
âAs you can see, Iâm still working on the engine.â
âCan you make it in time?â
âItâs not like I have a choice. Donât worry. Prototyping usually takes time since itâs hard to correct errors once I start the production process. Thatâs why I have to be meticulous right now.â
âAlright. By the way, what about the thing Yiruki talked about?â
âOh, that? I got it yesterday. This one.â
Nade threw a hose-like string at Shironeâs feet.
The outer material was made of rubber, and a transparent, membrane-like quartz filled the inside.
It was an item that Yiruki specially requested from his father, the head of the Kingâs Commission.
âOptical fiber.â
According to Yiruki, 300 holographic devices had to be set up in the academy.
However, it was impossible for Shirone to cast photon output to all the devices by himself.
In the beginning, Nadeâs first solution was to use a mirror.

It was a method of transmitting the photon output to the mechanical device using the lightâs property of total reflection.
But the problem was that there were too many places where the light had to be bent. So Nade thought âwhat if there were a lot more mirrors?â What if they attached mirrors to a small hose so light could âbendâ?
When Nade proudly proposed his idea, his eyes brimmed with excitement. This was because if this idea worked, they could commercialize it. They could sit high up on a pile of money.
However, Yiruki broke the news to them.
Yiruki received a letter from his father every month. It contained several pieces of information regarding the mage society. A letter from a few months ago wrote that the same kind of item Nade had thought of had already been introduced.
It was named the âOptical fiber.â
Nadeâs disappointment could not be put into words because even the Ivory Tower, which was at the cutting edge of magic, had only recently started to make developments in the field.
However, after receiving and analyzing the optical fiber, his disappointment disappeared. At his current level, he could never make such an item that required sophisticated engineering techniques.
âBut his idea was the same as the Ivory Towerâs. Nade is amazing, too.â
Shirone scrutinized the optical fiber. He couldnât tell what was so great about it with his bare eyes alone.
âHe really managed to acquire it.â
Nade, who finished welding, stood up with red eyes.
âPerformance is not guaranteed. Letâs start with a demonstration. Thereâs something I converted into a tester.â
Nade handed over the optical fiber to Shirone, which was equipped with transparent beads.
âWhat should I do with this?â
âKeep holding and testing the photon output. Iâll calculate the efficiency, so try it right now. But you really have to give it your all because measuring the maximum is important.â
Shirone checked the time and found out that his break was over, so he hurriedly grabbed the crystal ball.
When he cast Photon Output, a light source formed on top of his hand, and the beads shone pale.
That light traveled through the optical fiber to the device Nade created which caused the needle in the instrument panel to shake.
Nade, who was watching the numbers in the panel until Shironeâs output limit of three minutes passed, sighed and said in a sullen voice.
âYiruki was right. This is still in its very early development. Well, I guess I shouldnât complain and be ungrateful. We should still be thankful for this alone.â
âIs it that bad?â
âIt is only 18% efficient. That means 82% of the amount of light you sent was lost.â
â82%...â
Shirone was so very disappointed as soon as he heard the percentage.
It was hard enough for him to hold out 10 minutes, so the device having only 18% efficiency meant that he had to increase his output by 5 times to reach the desired value.
âCan you do it, Shirone? If you canât raise it, we will not succeed. Machines cannot compensate for a high output energy of magic.â
Shirone's head bobbed.
âIâll try. Iâm sure Iâll be able to after practice.â
âYou can really do it?â
âYes. Donât worry. Iâll do my best. Then Iâll leave to practice some more.â
Nade face scrunched up, and his eyes welled up in tears.
âReally? Youâre really going to it? No taking back.â
âYes, I said I will!â
Shirone spoke with confidence, but only his eyes were smiling.
* * *
âHaah! Haah!â
Shirone was on the ground, his body spread out. He was gasping for air.
Training Photon Output for over half a day was affecting his mind as well as his physical body.
The time he just achieved was 3 minutes and 20 seconds.
Nothing changed much compared to the record measured in the morning.
However, he was now able to reach 3 minutes and 20 seconds despite his drainged mental strength, so he could still say there was some improvement.
Considering he fell to 2 minutes and 34 seconds an hour ago, he did pretty well for the last-minute effort.
âEven so, it's far from enough. How can I achieve 10 minutes?â
For all he knew, it might have been impossible.
Photon Output consumed mental power much faster than single-shot active magic, if he continuously cast and maintained it. Ten minutes in that state was only possible in the professional world.
âHooh, I donât know. Iâll recover first and try again tomorrow.â
Nade entered the store room.
âShirone, are you done?â
âYeah. I canât do it anymore today, even if I die. I need to rest first.â
âIâm dying of exhaustion after watching spark after spark for hours. Itâs past midnight. Letâs head back to Yiruki.â
âHas it already been that long?â
After some short calculation, Shirone realized he had been practicing photon output for more than seven hours. It was a life-threatening amount of training.
If the academy found out about it, they would definitely ban him from training.
âUrgh.â
Shirone groaned as he lifted himself up from the ground with much difficulty.
Shirone wasnât the only one who looked like an undead creature of the night. Nadeâs eyes were sunken, and his face was blotchy red from the exposure to light for a long time.
When they returned to the research group, Yiruki was playing with a pen while viewing the academy from a birdâs-eye view.
He was doing this to organize the behavioral patterns into an equation while considering the variables that could occur on the day of the operation.
Nade understood.
Like Shirone and Nade, Yiruki also seemed to have never moved from his seat ever since he sat on it.
âWhat do you think, Yiruki? Howâs the math going?â
Yiruki didnât even look up from his notebook.
âI can manage to make it on time, so lay down your worries.â
Nadeâs heart ached as his greed seemed to only harm his friendsâ bodies.
In the end, the existence of the research group was one of the things the president had to be responsible for.
âYiruki, you donât have to overdo it. In fact, calculating all the behavioral patterns of all studentsâŚâ
âI can do it. I said I can do it. Donât talk to me. Iâm busy right now.â
With that, Yiruki shut his mouth.
He was writing formulas in his notebook at an alarming rate.
