I Think My Fiancé Has Regressed

Chapter 74: The Final Battle (1)

Last day of school for the first semester of my fourth year at the Academy.

It’s usually my philosophy to never miss a regular class, but today I took a sick day and spent the morning preparing for the final battle.

I wiped the blade of my holy sword, which I’ve already swung a thousand times, and began to reminisce about the changes I’ve made so far.

If I could sum up my life in my previous life in one word there is probably no other word that can describe me better than the word ‘regret.’

From the day I first met that girl after entering the academy, to the moment I collapsed with my heart in my hand in the final battle with the demon king.

Every moment of my life has been a wrong choice, and every decision I’ve made has come back to haunt me with even greater regret in the future.

I couldn’t trust Ariana until the very end in the trap that that woman had set.

Breaking off my engagement to Ariana and severing all the connections she had made with my own hands.

All of it came back to haunt me in the future, in the form of my predestined destruction. By the time I woke up, I was beyond repair.

For me, who had been defeated so badly in the last chance Ariana gave by risking her life, this second chance was literally the last gift she gave me.

If only I’d come to my senses sooner.

If only I had been able to catch him in the act of resurrecting from the magic stone in the depths of the Academy and defeat him in that moment.

I would have been spared the countless sacrifices and suffering that followed.

The memories of the day he destroyed the Academy and disappeared are still vivid in my mind.

The way he sneered at the woman who had used light magic against him as if she were an idiot and disappeared into thin air.

“What the hell do you think you’re doing, do you seriously think that stupid tickling ball of light is going to work on me?”

“Why aren’t you falling down, you’re supposed to die from being hit by light magic!”

“With that attack, which is not even basic magic, let alone low-level magic, you are going to kill this great evil and the Demon Lord of Destruction?

You must have heard a lot of rumors about me while I was asleep to bring such a lowly magic that couldn’t even kill a slime as my countermeasure.”

She puffed out her chest as if she had some sort of power, but could only watch helplessly as the demon flew through the academy.

While he continued to build up his power by destroying the world, I was busy dealing with the unexplained proliferation of demonic abnormalities across the country.

Add to that the constant turmoil within the country, which coincided with my own preoccupations.

Charlotte’s rebellion against me for abandoning Ariana, Eamon escaped his detention and fled into exile with her and then there’s the woman’s never-ending campaign against the state.

Like a snowball that starts rolling, it quickly grows larger and rolls downhill.

No matter how much I tried to clean up and organize these tricky cases, they would come back to haunt me as new ones.

When I finally felt strong enough to think that I could somehow defeat the Demon Lord, he had already transformed into a much more difficult opponent to defeat on my own.

I failed to defeat him at the last moment, and I finally gave in to my aching heart and died.

That was less than a year after I graduated from the Academy.

I still don’t know what brought me back to the past, or what caused it.

Perhaps Ariana’s saintly powers pulled me back in time.

Or perhaps it was the power of light from my shattered holy sword in battle that granted me my most fervent wish.

If not, did the ‘wish stone’ I received from her in my previous life really grant my wish and send me back to the past?

Or maybe it was something else. I’m not sure of anything.

So I have no choice but to face it with all my might, as if this is my last attempt.

~The afternoon of the last class day of the first semester~

I left my dorm for the first time in a long time, clutching the Holy Sword of Protection.

Perhaps today, I will have to fight a final battle against my old enemy.

* * *

There are only a few hours left until the final battle with the Demon Lord.

We already know that the Demon King will be resurrected this evening in the central depths of the Academy.

We’re not exactly trying to stop him, but rather waiting for him to rise.

There are three main reasons why we are not attempting to prevent his return and the crisis it will bring.

First, the power chamber at the center of the academy’s depths, where the Demon Lord will be resurrected, is a facility that is normally off-limits to the general public.

The central magic stone that powers the entire Academy is so powerful that even getting close to it can kill you from too much magic poisoning.

Because of the danger, even high-ranking nobles and royalty are strictly forbidden to approach it.

Even if they did, it would be impossible to physically wait for them at the resurrection site.

The second is that there are already very few ways to deal with the demonic seal.

The seals of the Demon Lord were accomplished by the combined efforts of thirty Archmages more than a few hundred years ago.

Even if there is a difference between the skills of the Archmages of the past and the Archmages of the present, it is impossible for me and Alex to fix the seals that mixed the power of thirty Archmages.

Besides, my dark magic wouldn’t be much help with the sealing spell.

Even if I could somehow interpret it to extend the duration of the binding, it would only be a few years before the seal would weaken again.

If the Demon Lord were to resurrect when someone like Alex it’s not at the academy it would be a disaster.

I’d rather resurrect him now, while Alex and I are still at the Academy, so we can take him down with the least amount of damage.

And the final reason has to do with Alex’s medical condition.

In order to cure his heart disease…or more accurately, to provide a temporary measure that mimics a cure, the presence of my dark magic is essential.

And what I need to use that dark magic is, of course, dark power.

In order to secure this dark magic power, I intend to defeat the Demon Lord.

A demon is a creature that was created by the magic in nature.

As such, when you defeat a creature made of a certain type of magic, the magic it possesses is temporarily released into the atmosphere.

In the case of a Blue Slime or Giant Crab Krevel was the blue color of water.

Even monsters that don’t seem to possess any particular type of magic are usually defeated by spitting out a small amount of arcane energy.

And the Demon Lord, like me, is a dark magic user.

It’s still hypothetical, but I’m guessing he’s probably a type of demon as well.

If so, the moment I deliver the final blow and cut off his breath, he will surely collapse, spitting out dark magic from his body.

If it’s powerful enough to be labeled a Demon Lord, the amount of dark magic it spits out will be no small amount.

That’s what I’m aiming for.

I’ve never tried it before, but if I can borrow the dark energy scattered in the atmosphere and use it to create magic.

If I can combine that with the magic amplifier Miss Sophia made for me, and reduce the amount of magic I need to use.

I’ll have enough magic to heal Alex’s heart.

To do that, of course, I need to revive and defeat the Demon Lord.

I’ll need to start treating Alex’s heart disease as soon as the battle is over, so I’ll need to conserve as much magic as possible for the rest of the day.

“Kooo, kooo!”

“Pooh, are you hungry by any chance?”

“Koooow!”

Purr hovered over the table, wooing me.

Normally, I would have fed her breakfast and then lunch, but I had to conserve my energy for today, so I hadn’t fed her yet.

I gently stroked Purr’s head as she turned her innocent eyes toward me.

“I’m sorry, but I can’t give you any magic power today, it’s a big day.”

“Koooooo….”

“Instead, I’ll feed you more magic tomorrow, just bear with me today, Purr.”

“Ku, kuuuu….”

As she stretches out on the table with a despairing look on her face, a strange feeling of guilt rises in my heart but it’s times like this when you have to cut and run.

Tucking my sagging Purr into the pocket of my dress, as if she didn’t have the energy to walk on her own, I walked to where I had arranged to meet Alex.

It’s time to face the end of the story.
