1.
A certain oddity utilized as a sort of cheat code in the original work.
The Card of Adulthood.
While its true abilities haven’t been definitively revealed, one could speculate on some of its capabilities by observing what happens after it’s used in the main story.
From being able to summon students registered on the ‘student roster’ despite not being in the same space…
To enhancing the abilities, skills, and even mysteries of students through a special item known as a “Clear Crystal.”
In short, the ‘Card of Adulthood’ was a type of reality-altering device.
It transcended the constraints of time and space, using the teacher’s life, time—and perhaps even lifespan—as a cost to manifest their desires in this world.
This was the ability of the ‘Card of Adulthood’ as judged by Nanashi Hiiro.
Strictly speaking, it leaned more toward the occult, and calling it magic wouldn’t be far-fetched. Despite being an immensely powerful ability, the cost was undoubtedly steep. However, because of its overwhelming power, using the Card of Adulthood in the story was practically synonymous with the teacher’s victory.
When the teacher used the ‘Card of Adulthood,’ it was essentially a declaration that they were willing to pay any price to win the current fight.
Hence…
<Tatatatatang─!!>
<Kwaang─!!>
Even if the opponent was an automaton driven to terror, it would be impossible for them to withstand the students imbued with the teacher’s strength.
Moreover…
“Nonomi! Create a smoke screen at the front!”
“Serika and Haruka, spread out and cover the two of them! Take out the shield soldiers first! And Chinatsu, tend to the wounded from the rear!”
“Prefects, stay where you are and protect the citizens while taking out the enemy artillery and drones!”
“Aru and Kayoko, snipe the direction the two are advancing, Muttsuki, throw the explosive bag at the 2 o’clock direction! And Iori and Shiroko, follow the two and sweep away any enemies in their path!”
With the teacher’s command added…
Even if the apparition of Maestro’s recreated past should confront them, it would inevitably crumble like a sandcastle before a wave.
The teacher’s instructions to the students at this moment were neither particularly special nor tasked them with any critical roles.
It was simply asking each student to do what they were capable of…
Highlighting the individuality and specialties of the students…
And combining these specialties to open a path for Hoshino and Hina as they moved forward.
“Yes, teacher…!”
“Yeah, I’ll do it. Just trust me.”
“Guh…! Understood…”
The students, upon receiving the teacher’s commands, had no choice but to nod in agreement.
It wasn’t merely because the teacher’s commands were accurate that they marveled at them and approved.
In this chaotic battlefield, they recognized the teacher as the most rational being capable of sound judgment, and they fully understood the fatal consequences of a dispersed command structure in such a situation.
And because they judged that the teacher—him—would make a decision for everyone, they nodded.
Thus, they followed the teacher’s decision…
And upon witnessing the shifting battlefield, they finally marveled.
Setting aside the astonishment at the semi-transparent hologram that appeared before the teacher, they could tell that the teacher was detecting everything happening in this space, giving commands that adapted to the changing battlefield at every moment.
No matter what variables arose, or what unexpected changes occurred…
They promptly placed the right person in the right position, devised the necessary methods on the fly, and broke through the situation. It was enough, even without grandiose strategies.
Because of this ability, the teacher was described as far superior in the skill of ‘command’ than anyone else in Kiburatos.
That way…
Though it wasn’t at an overwhelming speed, the scales of the battle against the automaton gradually began to tip in favor of the teacher and the students.
In the end, the teacher was able to achieve their desired outcome.
“This is it! You two, go now!”
Carving through the ceaseless barrage of cannon fire and creating a momentary gap somehow—
A fleeting second where the enemies’ attention was scattered, and no interference could occur. The teacher crafted that exact instance.
Without missing this signal, the teacher shouted, feeling the enemy’s scattered focus slowly returning, but unworried.
<Tokwaang─!!>
After the signal was called out, the two girls darted through the battlefield like lightning, rushing toward the formidable enemy.
2.
[Hoshino-senpai! Get out of the way!]
At Ayane’s urgent cry from her earpiece, Hoshino didn’t hesitate to push off with her foot and dodge.
<Kwaang-!!>
A massive steel tail, swung by Binah — the steel serpent — crashed into her previous position.
Hoshino could only chuckle nervously at the chilling feeling of danger she had just escaped.
‘To go this far against something like this?’
While it wasn’t apparent from afar, close-up, the situation was now clear.
Overwhelming size. A terrifyingly ferocious presence. An almost animalistic reaction and aggression. It wasn’t hard to imagine that getting hit even once could obliterate her entire body at once, crushed under its immense weight.
<Ppereng-!>
“Guh…”
Without a moment to even think, Hoshino had to move again to avoid another incoming attack. There was no time to stop and ponder her own judgment; Hoshino and Hina were moving their bodies quickly.
Cannons firing from the beast’s gaping mouth—a pattern unseen in the battle with Silk.
<Bam!>
<Bam!>
<Kwaang!>
The concrete ground shattered into powder as the hot energy hit it. Hoshino and Hina split in different directions, dispersing the incoming cannon attacks.
The patterns didn’t stop there.
<Keying─>
Kwaaaahaaaaaa──!!!!!
Within Binah’s mouth, massive energy coalesced and erupted as a powerful energy beam.
“What the—”
“What…?”
Hina and Hoshino instinctively perceived the impending threat and darted away.
And they saw the aftermath.
The objects struck by this attack were charred black.
An overwhelming attack that incinerated everything it touched along a straight line left Hina and Hoshino in shock and confusion.
Because—
[Artillery pattern, laser pattern… these patterns have never been observed before! They weren’t seen in the battle with Silk. Why now…?]
[Moreover, Binah’s reactions have become more intense compared to before. It’s likely due to the damage inflicted by Silk.]
All these patterns they were experiencing now had never been seen in the battle against Silk!
Many questions arose, but there was no time to deliberate on them. More precisely, such concerns weren’t something they needed to ponder themselves.
[Ako-san, what do you think?]
[…Apparently, we need to focus on the differences between the previous battle situation and the current one. The critical difference—]
[The difference between ground and air?]
[Yes, it seems to be about that.]
Hoshino and Hina were supported by their operators, Ayane and Ako, who would think things through for them.
Thus, Hoshino’s and Hina’s tasks were straightforward.
To fight this monster head-on!
But how? The biggest problem at the moment was that Binah’s cannon fire prevented them from getting close.
There might be unknown patterns they hadn’t identified yet.
Above all, they hadn’t found a way to land a solid hit on Binah.
They had to find a way to resolve this situation.
‘…’
Hoshino couldn’t help but recall one particular girl.
A hero who had struck this monster differently.
A girl who had given her an epiphany.
The fighting style of the girl who used her shield in such an extraordinary way, much like herself.
“Haha, I don’t know if this’ll work, but…”
Adopting such a strategy would completely upend the fighting methods she had used until now. Prioritizing the shield over firearms.
It was a form so extraordinary that it was unimaginable for anyone to replicate.
But despite that…
“…Alright. It’s worth a try.”
Hoshino, deeply impressed by the girl, found herself wanting to try it once she had come to this conclusion.
If no obvious solutions presented themselves, wasn’t it worth taking a gamble?
<Ggudeuk->
Hoshino clenched her left arm tightly, gripping her shield.
Through the bulletproof glass attached to the shield, she saw countless cannon shots being fired at her.
If even one hit her directly, she wouldn’t make it.
The heat grew closer, causing her that realization.
For a fleeting moment, she could see the shocked expression of the Leader, seemingly understanding what Hoshino was about to do. That shock quickly transformed into a look of determination.
Hoshino, mirroring that determination, prepared.
Then, Hoshino “swung” her shield toward the oncoming artillery, as if batting away incoming balls.
<Turoooong──!!>
The sensation of weight and stinging pain in her wrist and arm came from the recoil of the shield, something she had used only for defense until now.
However…
The result matched the effort.
The deflected artillery struck the ground, exploding.
She had successfully blocked the attack.
“Huff…”
Though the shield showed slight damage as a result, it didn’t matter. Knowing her shield didn’t use the same special materials as Hiiro’s, she understood that enduring these attacks indefinitely was nearly impossible.
<Kwaang-!!>
Blocking another attack, Hoshino advanced.
‘To give up flesh and take the bone, wasn’t it?’
If she could strike the monster using her shield as the cost, it would be a profitable deal, considering her primary goal was merely to imitate.
Hoshino smirked slightly, accelerating her run toward Binah.
“Let me draw its attention! You can count on me to cover the rear, Leader…”
3.
Silk’s fall was a sight that wouldn’t leave her mind.
To Hina, Silk wasn’t just anyone; she was an immensely powerful superhuman.
A literal “hero” who never fell, no matter the pain or adversity, and overcame every trial.
The moment Silk was struck by Binah and plummeted down had been etched into Hina’s mind.
At that instant, a gloomy, dark emotion had filled her.
What could be called “despair” gradually gnawed at her mind but eventually turned her into burning anger.
For Hina, who had come to regard Silk as an idol, the feeling of animosity toward Binah, which had harmed such a Silk, was natural.
Was it the emotion of a friend seeing someone they cared about hurt?
Or was it a desperate struggle to cover her despair?
Hina had neither the time nor the leisure to sort through these emotions.
Since some point, all that remained for Hina, who kept looking toward where Silk had been, was to rush forward in her place.
Thus, Hina charged forward.
She ran toward the battlefield where the mighty enemy was, alongside Takanaashi Hoshino, who she secretly admired greatly.
And she saw there.
The traces of just how brutally Silk had been beaten.
And herself, called the strongest of an academy, helplessly being battered by the enemy’s attacks.
As well as Takanaashi Hoshino, who was finding her own way through the obstacles with her own methods.
<Ppa-dek->
Clenching her teeth without realizing it, to the point of grinding them.
She could feel how pathetic her inability to achieve her long-desired vengeance made her seem.
[Leader! Now’s the time! Let’s attack the steel serpent while Hoshino-san is distracting it…!]
“…”
[Le, Leader?]
“…Yeah. We have to do it. Somehow.”
Hina gave a hollow laugh at Ako’s call and had no choice but to move forward.
Hina grit her teeth and pushed off, sprinting forward with all her might.
Hina, with superhuman physical abilities, closed the distance with the steel serpent in an instant, like a cannonball.
<Kwaang!>
With each step, a sound like an explosion echoed through the battlefield.
In that moment, Hina wiped away all the swirling thoughts in her mind and harbored only the single-minded desire to knock down the enemy.
To make use of the opportunity created by Hoshino.
Her determination was clear: she wouldn’t let this opportunity go to waste.
<Kwaang!!>
<Kwaang!!>
<Kwaaang!!>
Unfolding her wings, which she usually just mentioned idly, and using every means at her disposal, Hina ran with all her might.
Or rather, any observer would think she was flying because of how instantaneous her movement was.
Binah tried to interfere midway when it realized Hina’s approach, but it was no match for Hoshino’s diversion and Hina’s instincts.
Moving forward, moving forward, and then she reached her destination.
Hina found herself standing right in front of Binah.
And…
“Target confirmed. Attacking!”
Hina unfurled her wings fully, radiating a violet glow as she exuded a ferocious aura.
Her massive gun, aimed at the serpent’s belly, gathered an overwhelming energy that clearly spoke of her will to sever its torso.
An energy charged with her hostility towards Binah.
It was almost as if her grudge against Binah had manifested itself into mystic power.
<Kraaaaaaaaa─!!!>
Seemingly sensing this, Binah desperately turned its head, but Hina’s finger had been on the trigger for far too long.
Moments later, a violet beam of light erupted toward Binah.
Kwaagaaaagaaaaagaaaa──!!!!!
Just as Silk had once covered the city in a blue flash of light,
Now Hina covered the streets with a violet flash.
And it didn’t stop there.
“Hey, don’t you dare forget about me~!!”
Binah witnessed it.
Among the violet battlefield, a girl swathed in pink appeared, aiming her gun at Binah.
Even amidst the cries of pain, Binah attempted to retaliate but…
“No point…”
Hoshino’s declaration, instantly solidifying her expression,
“Losing you.”
The sight of Hina aggressively charging forward and unleashing relentless power despite having already delivered a mighty attack filled Binah with an instinctive fear.
Moreover…
<─────?!!>
From afar, the sensation of its old nemesis re-emerged.
At the thought of potentially being outnumbered by three enemies—or worse, the return of that “monster”—
Binah knew its defeat and death would be certain.
It needed to quickly deal with the two girls.
Or escape!
Binah made its decision quickly and acted with equal speed.
“Huh?”
“Huh?”
Binah disappeared into the ground, leaving Hina and Hoshino in utter bewilderment before they quickly realized the situation.
<Kugu-gu-gu-gu-gu…>
The vibrations reverberating from beneath the ground…
They told everyone that Binah wasn’t backing down just yet!
Then, immediately…
Pwweeewwwweeerrrrr──!!!!
The sudden eruption of Binah from underground.
A massive sandstorm surged through the streets of Abidos once again.
“What’s this nonsense?!”
Hoshino’s cry, full of indignation, echoed the sentiments of everyone present.
