The Infinite Dimensions Starting from The Irregular at Magic High School

But thinking back to that decisive move just now...

This Yotsuba underclassman might be even more formidable than they had imagined...

At magic science schools, magicians were stationed there as teachers in order to instruct students in practical magic skills.

First High School was recognized as the highest-level magic science school, and its teachers were all first-rate magicians as well.

The combat strength of this school was enough to repel the army of a small nation on its own.

The problem was, if they faced a sudden attack without any preparation, they would still be forced into a passive position.

And that was exactly the situation now.

The campus was already engulfed in battle.

Broken trees. Deep craters visible everywhere on the ground.

The terrorists had rammed the school gate open with trucks and broken into the school grounds.

RPG rockets that belonged in a museum were flying all over the place, and homemade incendiary bombs had blackened the walls of the school buildings.

Two teachers were working together to deal with the flammable viscous agents that continued to burn.

Meanwhile, the other students and teachers were engaged in combat with the invading terrorists.

"There's a lone magician here! Take him out!!!"

He had barely arrived in the central courtyard when he was spotted by several terrorists.

They raised their guns, aimed, and fired in one smooth motion, without the slightest hesitation.

Even at the end of the twenty-first century, firearms remained the primary weapon of infantry.

"Pretty good shooting. Looks like these Blanche people aren't that simple."

Faced with a barrage dense enough to seal off his movements, Mahiro showed no trace of panic. He simply raised his hand, and psion light immediately wreathed his body.

Like a protective barrier, the bullets were decomposed into molecular form the moment they entered a range of less than one meter.

No matter how many bullets flew at him, the final result was the same.

They could not harm him in the slightest.

Nihility.

Psion light flashed again.

The terrorists' bodies instantly distorted, and along with their weapons, they were decomposed into dust.

"The library, huh? What an easy-to-read objective."

A faint arc of light flashed through Mahiro's eyes as his gaze turned toward the library that had already been invaded.

That made sense. In First High, aside from the students themselves, the only truly valuable things were the materials on modern magic.

When he moved again...

The rockets dragging trails of flame overhead were also casually dealt with in passing—

Several dry-ice bullets appeared out of thin air and shot out like bullets, striking the rockets scattered high in the sky one after another.

"Is that... my Bala?"

After maintaining order in the auditorium, Mayumi and the others came outside and froze when they saw the fireworks blooming in the sky.

"That is far too shocking..."

Mari Watanabe's voice was thick with astonishment, while Mayumi had already gone completely dumbfounded in an instant.

Bala was a secret art exclusive to the Saegusa Family!

It was a composite-system magic, "Meteor Stream," that slowed the movement of air molecules to create dry ice, then accelerated it to subsonic speed, combined with the perception-system magic "Multiple Observation" to snipe targets!

Aside from Mayumi being able to use it alone, under normal circumstances it required two people working together, just like her two younger sisters, Kasumi Saegusa and Izumi Saegusa.

But she never expected that Mahiro would actually have mastered it now!

Not only could he use it, he did so cleanly and decisively, with a level of proficiency no worse than hers!

And when it came to facing enemies with such composure, perhaps only that Crimson Prince of the Ichijo Family, Masaki Ichijo, could manage the same.

Mayumi's gaze toward Yotsuba Mahiro grew somewhat complicated.

After all, whether it was that decomposition magic or Bala, neither of them were magical characteristics the Yotsuba Family excelled at.

And among those present, the only ones who knew the reason were Shiba Tatsuya and Miyuki Shiba.

This was the unreasonable nature of the Alpha Stigma.

The bearing Yotsuba Mahiro displayed at this moment also made Shiba Tatsuya feel an even stronger sense of familiarity.

That terror of being able to annihilate enemies every time psion light flashed.

Just like the him who had once launched that war of vengeance—

The one known as the Demon of Okinawa, Mahesvara!

The library was utterly silent.

Aside from the staff, there should have been a large number of guards stationed here around the clock, but now not a single person was in sight.

At a guess, they had all been captured.

To subdue this many magicians, it seemed this group had come prepared.

Mahiro hid in the shadow of the counter by the entrance, spreading his awareness outward with the perception-type magic "Eidos Eye" to probe the first floor's defenses.

Seven in total.

Four of them were fully armed and hiding behind pillars.

There was also one student keeping watch in the second-floor corridor, and three more inside the special reading room at the far end.

However, during his scan, he discovered that every one of them was wearing a brass ring, and the gemstone set into the top was...

"Crystal Sun Stone?"

Crystal Sun Stone was a military resource with extremely limited sources. It could only be found in prosperous regions of ancient civilizations at high altitudes.

And Crystal Sun Stone had only one function.

It released interference waves that disrupted calculation, obstructing the effects of magic activation sequences.

For a magician like Yotsuba Mahiro, who could directly read activation sequences, it was nothing more than a heap of irritating noise.

But for the guards and teachers in the school, it could prevent them from casting magic. That was why they had been defeated by these terrorists.

"Forget it. Calling roll one by one is too much trouble. I'll just deal with them all at once."

After withdrawing his awareness, Mahiro gave up on the idea of using "Nihility."

As an intense release of psions erupted, the first floor of the library was instantly covered in the glow of magic.

Immediately afterward, dense white mist formed from frigid nitrogen surged forth, spreading and rolling across the entire floor.

The snow-white fog stirred into whirling currents, and everywhere it passed was covered in frost.

It was as if liquid nitrogen had been poured across the ground!

By the time the terrorists on guard noticed, it was already too late.

"Wh-what the hell is this?!"

They had never seen this kind of magic before!

By the time they tried to dodge, it was already too late. They could not even move a single step.

Their frozen feet could not support them moving forward, nor could they retreat.

The bone-chilling white fog gradually climbed and coiled around their torsos, corroding and seeping into the deepest parts of their bodies.

Not only their flesh—even their souls seemed to be frozen.

In the blink of an eye, they had already turned into ice sculptures one after another!

The entire first floor of the library had practically transformed into a silent, deathly Crimson Lotus hell!

"Whoa, that really is an over-the-top spell. Don't tell me this is the wide-area vibration deceleration magic—'Ice Fog Domain'?"

"Hey, Yotsuba, is there any magic you actually don't know?"

Erika, who was also hiding behind the counter with half her head poking out, chattered away as she expressed the shock in her heart, breathing out puffs of white mist as she did.

First there had been that magic that directly erased the enemy, then the Saegusa Family's secret art, Bala, and now he had shown vibration-type magic too.

Not a single one of them was below A-rank.

"Erika-chan, this is only the tip of the iceberg of what Brother Mahiro can do."

Miyuki smiled and answered on Mahiro's behalf.

As a fellow member of the Yotsuba Family, she knew perfectly well just how absurd this elder brother of hers was.

Any magic he had seen, he could perfectly reproduce. Even strategic-class magic was no exception. Up to now, he had already learned at least over a hundred kinds!

They covered the four major systems and eight major categories, and even magic outside the system and non-systematic magic.

"All right, save the chat for later."

Mahiro spoke up, cutting off the conversation between the two of them.

The reason they were here was naturally that they had followed him on their own.

On the way, he had run into Erika, who was being entangled by enemies, and rescued her. Then, when he arrived at the library's main entrance, he happened to meet the Shiba siblings.

"There are still a few enemies in the special reading room upstairs, so I'll go up by myself from here—"

"Huh? Brother Mahiro is going up by himself?"

Miyuki said in astonishment, "Please allow Miyuki to accompany you. Although Miyuki knows she may not be of much help, it is still better than facing the enemy alone..."

"All right. Miyuki, you and Tatsuya can help me guard the library entrance. That'll be the biggest help you can give me."

Mahiro reached out and stroked the girl's long hair, and Miyuki immediately quieted down.

Though his words carried a hint of placation, now that he had put it that way, Miyuki could only nod and agree.

"Then, Erika, if any ambushers slip through from upstairs and come down, I'll leave them to you."

"Ambushers?"

Erika looked at him strangely, then jabbed him a few times with her elbow, her face full of teasing.

"Don't tell me it's Senior Mibu? You really are something~ You're actually weirdly gentle~"

"Well, I wouldn't call it gentle. When entrusted with a task, one should do it faithfully."

He hadn't forgotten Mayumi's request before he left, nor the request from that pervert teacher who had been tailing a student.

"Physical persuasion is fine too, right?"

"Of course."

"Hehe, then I'll take the job~"

Erika accepted the task as if she were singing.

And Yotsuba Mahiro had already gone silently up the stairs.

Perhaps because the guards on the first floor had gone down too quickly, without even enough time to make a sound, the Kendo Department members keeping watch in the second-floor hallway failed to notice anything unusual.

He dropped them on the spot and tossed them aside.

At the very end of the hallway ahead, behind that tightly shut door, was First High School's special reading room.

It contained all sorts of valuable records on the composition of magic formulas and experimental data.

Though it could not compare to the records at Magic Association headquarters or the volume stored at the Magic University, even so, to a weak organization like Blanche, it was absolutely precious.
