In the darkness of the night, snowflakes transformed into strands of green silk as they streaked across the sky and gently fell onto the playground.

Everything around fell silent at that moment, and the green lawn was stained with a large patch of red. The massive lion lay decapitated, its body sprawled in a pool of blood.

"Wuwuwuwu..."

My head felt like it was about to explode, and my world was being consumed by darkness.

"Who am I...? Hahaha, die, everyone just die. Tonight is the time for me to seek revenge!"

Wait, why am I saying and thinking such corny things?!

I lowered my head and looked at my hands. The blood vessels grew deeper, until both hands and forearms were covered with blood-red clots, like stones formed by coagulated blood. The throbbing pain was a constant torment.

"Let me kill, let me kill. I'm addicted!"

Some black substance oozed from the scabs...

Looking at these obvious and exaggerated changes, I wondered: can I still be considered human?

"Ughhhh...!"

Staring at the black longsword in my hand, I let out a series of screams, which reminded me of what Teacher Fuyu had told me that day.

"After summoning the demonic sword, the host's blood is gradually consumed every minute. It's true!"

Although it lacked the dazzling features of a sorcerer's magical tool and had a limited variety, the demonic sword indeed belonged to the category of magical tools.

It was warning me, warning me about this lifetime.

Perhaps I would never have the chance to go on like this again because I am the kind of person nobody loves, even the love from my family feels distant.

"Why, brother... why did you abandon me...? I'm calling out to you!"

The silhouette turned into my sister's face for an instant, but the information I obtained in that moment was enough.

"Do you hate me, sister?"

The only response was silent emptiness, echoing with my own voice.

"If you hate me, tell me why, and then take my life, as long as it can restore you to normal..."

I called out to her, but all I received was the same answer - silence.

Did I misunderstand your meaning again, sister?

"Liar...big liar!"

"Liar? Why?"

Suddenly, my sister shouted at me, unleashing countless things that I didn't understand, nor did I know about.

"You promised that you would never abandon me, but... but...!"

The intensity of everything around me escalated until I lost control, and that's when my sister's voice suddenly resurfaced.

"Why did you let someone else take my place?!"

"Huh? What are you talking about?"

"You said you would always keep me in your heart, but you treated someone else as your sister and took away the space that belonged to me in your heart! You..."

Unable to bear the mix of heartbreak and fury any longer, she couldn't stay any longer. And the cause of this outcome was me - Paroni.

In reality...

"Aaaaahhhh...!"

The demonic sword erupted with a burst of energy, its dark and blue flickering lights tearing open a large hole in the top layer of the barrier.

The academy also launched its final warning and evacuation announcement.

"All students and teachers, quickly evacuate outside the barrier. Remember, this is not a drill!"

The gates of Durma Academy swung open, and the students streamed out in droves.

"It was so close! Thankfully, we managed to escape from the dormitory building in advance."

"Yeah, now that you mention it, that blood-red armored monster didn't look like a paladin, did it?"

The two girls, who were relieved to have escaped, immediately began to recall the strange phenomenon they had witnessed earlier.

"That was indeed a paladin..."

"No!"

As the crowd discussed, a young girl with a youthful appearance but a mature and calm demeanor spoke up, her hair in braids.

"That was a blood-curdling knight, the vampire's ultimate weapon, the evil god!"

Just as everyone let out a sigh of relief, a beam of light shot up from the direction of the playground, and the sky instantly cracked open—a boundary had been broken!

Ah...!!

Things were not looking good. When I regained consciousness, the magical energy of the magical equipment had reached its critical point, and my muscles showed signs of tearing.

"My body can't take it anymore, can it?"

Oh well, it doesn't matter anymore...

I slowly closed my eyes, thinking that I had already become abnormal with the demonic sword possessing me, and even if I survived, I would be eliminated by the Imperial Capital's mechanisms, right?

"Instead of going through all this trouble, it's better to just die like this."

In my complete despair, I chose to give up the desire to survive, after all... after all!

I bit my lip and said,

"If this continues, many innocent people will die, won't they?"

Although I had no consciousness in the real world, I could sense that my real self was constantly eroding my own humanity.

This is not good if it continues, right?

"Paroni... is that you... brother?"

As I was enveloped by the uncontrollable power, my sister appeared before me once again.

Her sweet voice called out to me, awakening me from my slumber.

"Nana?"

"Don't lose your rationality... brother."

So many strange things have been happening lately, from the Snake incident to last night when I ended up sharing a bed with my deceased sister, and then mysteriously disappearing, as if I had evaporated from the face of the earth.

"If even you have become like this, what's the difference between you and those beasts hiding under human skin?!"

This voice calling out to me is not my sister, it's... it's Yukari, my classmate?

"No, you're not Yukari!"

When I looked ahead, a woman who looked a lot like Yukari but appeared more mature and experienced rescued me from the depths of darkness.

"Come out, are you really willing to die like this for a bunch of ants?!"

A black aura, roaring in anger, continuously emanated from her arms, and she magically conjured a small bottle of dark red liquid, pouring it all into my body.

"Ah...!"

A heart-wrenching scream erupted from my throat.

"This is... this...?"

"Demon's blood, your human body cannot withstand the staggering demand of the demonic sword."

"So you infused me with demon's blood?"

Although it doesn't sound like a good thing, at least it will save my life... I guess I can't just die like this.

The storm-like power of the demonic sword was instantly taken in by me, and with my spirit finally released, I succumbed to exhaustion and fainted.

Only clear, in the hazy illusion, there was a person standing by my side...

"Ugh..."

It's him again...the demon known as Lucifer, who saved me and is called the Demon King by humans!

At this moment, he is wearing a holy robe symbolizing angels and gods, it's pure and white.

"Are you..."

"Are you awake? If you are, don't just lie in bed!"

His index finger lightly brushed against my chest, and the tight bandage on it instantly turned into shining stars and disappeared.

"Huh, my wound is gone?"

"Yes, the power of demon blood can make your physical body stronger, just like vampires. So today, you should remember someone who helped you!"

"Uh, is it Yukari?"

"Yukari sister...ahem, not Yukari!"

Although his behavior just now was strange, he seems to lose that authority when it comes to Yukari.

"You must also thank the person who saved you. She is our faceless principal."

"The principal, did the principal save me?"

Although I feel disappointed, I still hold onto a glimmer of hope.

"This time, I almost collapsed to save you."

Although he said it lightly, it is quite shocking to me.

"Impossible! Can someone that powerful also get hurt?"

"Yes, just like me..."

He lifts his forehead, revealing an exaggerated mark.

"Everyone, even Divine Lords, have their weaknesses. You just haven't discovered it. Oh, I forgot to introduce your new teacher to you..."

"Hey, how long are you going to pretend to sleep there?"

Just after talking to me, he turned to the dark area behind the side of the door.

But, is there really someone there?

"Oh my, just when I was enjoying a sweet sleep, how can you have the heart to wake me up...Xiyu?!"

"Don't disgust me, go and take care of your students!"

He points at me while hiding under his cloak.

"Ahh~ Found you...human."

The man in front of me has a pale white braid and is dressed in a white cape and suit, like...a leader among vampires!

Is it SS-class? That's my bottom line.

I didn't expect them to send an expert above S-class to personally meet me. Is there something important?

"From today onwards, you will study hard with me!"

"Uh, is that okay?"

Although that guy puts his hand on his waist in a proud manner, he's not a bad person, right?

"So, have you made up your mind?"

"Why did you invite me to join your class?"

"Hmm, because I was also entrusted by someone else, but for personal reasons, I had to make you join my ranks."

"Had to...?"

Just as I was talking with that devilish man, the principal suddenly interrupted.

"Watch your words, this is the first prince of the Dark Empire..."

"That's right, it's me! The 17th emperor of the Dark Empire, and also the progenitor..."

"Unfortunately, after the empire's downfall, I could only do menial tasks for them."

"Hey, you're being too heartless!"

Before he could properly introduce himself, the principal poured a bucket of cold water on him mercilessly.

With his arms crossed and an extremely disdainful attitude, he mocked him.

"Ah, clearly you're one of the Four Emperors, but you don't look like a Four Emperor at all, am I right, Mr. Freeloader? Or can I call you by your nickname? Stupid..."

"Enough!"

Ancestor made a gesture to pause, and coldly refused.

"Hmmph, be careful what you say, don't mention that name, okay!"
