Accidentally Mistaken as a Genius Professor

[My disguise should have been perfect. Even the Progenitor Dragon’s eyes couldn’t see through my true form!]
The demon before me shouts.
A voice that seems to mix complex emotions: wariness toward an unknown being and the humiliation of having his disguise instantly seen through.
[Tell me. How exactly did you break my power?]
He asks while exuding a menacing killing intent.
Though his expression clearly showed bewilderment…
It was rather I who wanted to ask questions.
A demon?
Why is something like that appearing at this timing? Even at the earliest, shouldn’t it appear somewhere around the middle of the story?
Was it caught by coincidence? Did I just randomly pick on someone who happened to be trying to infiltrate the academy?
How could things get so tangled up? The overwhelming confusion makes me feel like I’m about to go insane.
[…So you have no intention of revealing your hand. Then I’ll have to find out for myself.]
But the situation didn’t wait for me.
His form disappears as if erased from the world in an instant. Shortly after, a voice comes from behind me.
[By the name of Amon, the 7th Rank, I promise. Your soul will burn in hell for eternity.]
There’s no time to hesitate.
I didn’t refuse to use the privilege the Empire had bestowed upon me. The spatial inscription glowing on my left hand.
Using something originally created for inventory purposes as shock absorption. Normally, such a thing shouldn’t be possible, but I wasn’t appointed as a professor for nothing.
Analysis and modification of magical formulas are my specialty.
If it’s about slightly twisting and utilizing an already well-completed formula, it’s entirely possible.
I feel the sensation transmitted to my back. I can feel his fist making contact with me, but the impact is minor.
The overworked spatial formula has broken, but fortunately, it seems to have successfully blocked this attack.
He clicks his tongue looking at me and takes a step back.
[A spatial formula… As expected, you were hiding your power.]
An absurd overestimation coming from the demon’s mouth.
He looks at me as if I’m some kind of monster. After threatening me with burning my soul and whatnot earlier, now he’s even sweating cold sweat in a manner unbefitting a demon.
While the demon was being cautious and couldn’t move freely, everyone else seemed to have regained their senses. The Elf professor next to me had raised his staff and shouted loudly.
“To think one of the 72 evil demons would reveal itself. We absolutely cannot let it escape from here!”
Everyone seems to be in combat stance.
At this point, there was no need to worry anymore.
Because the professors at the academy are all monsters themselves.
As long as they don’t get confused by some madman rambling about cotton-pickers like earlier, several professors should be able to handle one demon.
Let’s just observe the situation carefully and follow along for safety.
I had just come to that conclusion in my mind…
When I saw the door of the interview room.
And I thought of the children beyond the door.
I don’t really know what this Amon character is all about. But I do know what purposes demons usually have when they secretly infiltrate in academy stories.
Terrorism.
Their aim is certainly to cause as much damage as possible.
…I see the demon taking steps backward.
He’s cautiously peeking towards the door.
If only he would simply run away from here, there would be nothing more to ask for. But would a true terrorist really be satisfied with just escaping?
The children in his escape route.
Would he maintain his manners and not harm them?
‘There’s no way.’
There will definitely be casualties.
And that would clearly be my responsibility.
If things had followed the original story, the protagonist would have found and eliminated this terrorist. But it was none other than I who revealed his identity.
People who originally wouldn’t have died would lose their lives because of my actions. What difference does that have from me directly killing people?
My feet move naturally. The troublesome habit of taking action first and thinking later reveals itself once again.
Quickly blocking the doorway, I said,
“I cannot let you pass through here.”
It’s a gamble worth taking.
The odds are more than enough in my favor. I’m not foolish enough to risk my life in a fight with no chance of winning.
‘He’s definitely wary of me.’
A spatial magic user whose attacks have no effect on me.
It’s hard to think that a demon who sees me that way would easily rush at me again.
While I’m blocking the escape route, if either the professors subdue the demon, or if just one professor realizes the risk of students being taken hostage and takes measures, it’s our victory.
As long as he doesn’t suddenly become capricious and rush straight at me, I won’t lose.
So I just need to buy about 10 seconds of time…
Suddenly, an alarm sounds.
A student who peeked at the situation inside the interview room happened to press the emergency alarm button at this timing.
[Damn it, at this rate, that crazy lizard woman will…]
The demon frowns with an urgent look.
He was maintaining his distance and continuing his reconnaissance until just now, but now he’s quickly getting into position.
As soon as I saw that, I immediately sensed it.
I prided myself on having good luck in both my past life and current life, but this time, that luck wasn’t with me.
The demon, who became anxious due to the alarm and the threat of reinforcements rushing to hear it, chose to urgently escape from here even at the risk of facing me.
I shouldn’t have set foot in this hellish place. With such regret, I watched the approaching demon.
It seems he’s desperate in his own way. He’s burning all his demonic energy in this one strike.
As a last-ditch effort, I took out a protective dagger hidden in my sleeve, but it’s meaningless since I, who never learned swordsmanship, have no way to defeat him.
Several professors are urgently deploying formulas to protect me, but it’s a desperate surprise attack launched at such speed. It would be impossible to match it in time.
The demon’s outstretched hand.
An unpleasant feeling like caressing the soul.
Shortly after, a terrible scream echoes.
[Arghhhh!!!]
Not from me, but from the demon.
Opening my eyes that I had shut tightly in the incomprehensible situation, what enters my vision is the demon with a painful face.
Moreover, somehow, he’s been pierced by my dagger.
[I was sure I had hidden the core. Are you saying even that couldn’t deceive your eyes…?]
The demon cried out regretfully.
As I inadvertently twisted the dagger, he let out another terrible scream and began to burn brightly.
Soon, he had turned into a handful of ashes.
I stared blankly at the pile of ashes in a frozen state before coming to my senses.
‘…Did I win?’
Whether the dagger given by that old man was something special, or if he was just weaker than I thought, or if I just happened to hit a vital spot.
I’m not sure about that yet. But at least it was certain that I had survived this disaster.
As soon as I realized that, the tension finally eased.
‘I almost died on my first day at work.’
It was truly a miracle to have survived in such a hellish place.
I’ve painfully realized why I shouldn’t stay at the academy from what just happened. Let’s implement the plan and leave here as soon as the situation is settled.
I looked around with that conclusion in mind.
And met many gazes directed at me.
The elf who had cursed at me.
The old professor who had scolded my attitude.
Without exception, every professor present was looking at me with some strange gaze.
And to top it all off, a voice from behind.
“Hmm… I’ve chanced upon something interesting.”
Silver hair.
A face as beautiful as a sculpted work of art.
And two horns protruding above it.
“Would you like to have a cup of tea with me for a moment?”
The principal of the Imperial Academy.
The Empire’s Progenitor Dragon stares at me intently.
As if she had seen something very interesting, her eyes were sparkling.
…It seemed my grand plan for getting fired was being utterly demolished in real-time.

The interviews at the academy proceeded as scheduled even after the new professor was taken away for questioning.
However, none of the professors who remained there could concentrate on the interviews.
Even the old professor who had pointed out the new professor’s attitude and hinted not to think about other things during work now couldn’t focus on the student before him.
That was certainly unprofessional.
But who on earth could blame that old professor?
-Are you really going to let such a hideous thing into the Academy?
That professor had noticed the other’s identity from the beginning. He had precisely seen through the evil nature that no one else could notice.
He even used code words to subtly warn that the enemy was a demon trying to infiltrate the academy.
-I cannot let you pass through here.
That professor stood alone with dignity.
He showed no signs of agitation, to the extent that one might foolishly wonder if he had frozen in panic.
The man simply stood still.
He didn’t build a formula. He didn’t swing a staff. Yet the man completely overwhelmed that formidable enemy.
The man, who maintained silence as if unwilling to even converse with a mere demon, opened his mouth only once in anger.
That he would absolutely not let him pass through here. That he would never allow the students to be hurt.
When everyone was focused only on capturing the enemy to achieve merit, only he looked at the children.
When everyone was trying to kill someone, only that man was trying to save someone.
…How could one forget such a person?
How could one erase that image from their mind?
All sorts of extraordinary beings come to the academy.
The Holy Maiden of the Pontifical See.
The Empire’s 2nd Princess known as a genius.
A commoner who achieved top admission despite suffering from magic insensitivity.
All are uniquely exceptional individuals, but everyone present could be certain:
Among the many talents that appeared this year, the most distinct one would definitely be that new professor.
