The moment you step into the building, you will be greeted by a wonderful feeling.

I have the illusion that the color of the world has changed. The air is dry and has a grainy feel. It's not pleasant, but the air is also something to be missed.

Caihai School High School - This is a rare type of educational institution in the "Demon Special Zone". There are no special facilities for demon research on campus. It's just a commonplace high school. Although there is a strange atmosphere in this school now.

There were no students in the school building late at night, and the light of the emergency lights and the moonlight shone on the light and dark corridors.

On the blackboard of the unmanned classroom, dense words are written.

It contains spells written in exotic magical scripts. This is a verse from an old magic book.

The countless words written in chalk emit a faint golden light, releasing strong magical fluctuations.

That's an overwhelming force that can even change the world. Each of the words written above is a "door" to receive the power of the other world.

“…… Secret Affidavit ......"

Muttering to himself, the young man smiled slightly.

This is a young man with glasses and an intellectual appearance. The left hand was embedded in a lead-colored yoke, and the lock that was briefly pulled off swayed. He was also one of the seven escaped prisoners from the prison barrier. He is also a figure who is called the Underworld Driver by Shutra D.

The young man walked up the stairs with the sound of quiet footsteps, and soon noticed the figure lying in the hallway, and stopped with interest.

It was the remains of the Magus, slain by a giant sword.

The fallen Magister was armed with a sword, a staff, and a book of magic—magical weapons of great power. But they have lost their magical light and have been reduced to worthless rags.

They were robbed of their magical power by the wonderful air that filled the school.

"Are they the Magisters of the LCO—?"

The young man asked into the classroom.

Hearing the voice, it was a young woman wearing a black and white twelve.

"The Witch of the Secretary" Xiandu Mu Aye-

She held the shortened chalk in her hand, and on the blackboard behind it, a section from the Wizard Book was written in tiny words.

“…… Prison Escapees...... That's right. I remember it's called a dead car or something. ”

Looking at the young man's whole body expressionlessly, Ah Ye asked as he searched for ambiguous memories.

"It's just an ordinary retired demon attacker. Nothing. ”

“…… Obviously, they have walked into my 'world' as if nothing happened, and it is really a shame that you can say it. ”

Ignoring Ah Ye's hostile gaze, the young man raised his left hand to his eyes.

"Where are your flails, Xiandu Mu Aye?"

“…… What do you mean? ”

"If you take away Nangong's memories of that month, then of course, it should contain the 'key' to the prison enchantment - the lifting procedure. Even after Nangong escaped that month, you didn't plan to pursue her. That's because it's not necessary. ”

Staring at the witch's left hand, the young man asked.

The wrists hidden in her twelve sleeves did not have the shackles that were supposed to be there. Xiandu Mu Aye has been completely liberated from the prison enchantment.

However, she did not tell the other prisoners about the "key" to the prison barrier.

Thanks to this, the escaped prisoners except for the young people are still chasing Nangong Nayue. That month was used as bait.

But even in the face of these accusations, Ah Ye still said "so what" and laughed.

"Are you here to remove the dregs of the program, Wolves?"

“…… No. As for the solution to this, I also have a clue in mind. ”

The young man, who was called by the strange name of the other party, shook his head with a sigh.

Ah Ye showed a surprised expression.

"So, why are you here?"

"Just to see for yourself."

“…… Confirm? ”

"Hmm. Confirm what you wanted to do when we were attracted by Nangong's attention that month. ”

The young man who said this gently stepped on the sword that had fallen to his feet. The sword, which was supposed to contain great magical power, was now shattered with only a sound like dead wood.

"Is this the power of the Secret Oath?"

That's right, Ah Ye nodded as she spoke, and then put her eyes on the chalk in her hand again.

"The secret affidavit has lost its ontology. Nangong destroyed the book that month, and now the wisdom of the magic guide recorded in the book only exists in her memory. ”

"So you're going to take away her memories and reproduce the Secret Affidavit in this form...... I see, that's why you're called the 'Witch of the Secretary'—"

Looking at the secret oath written on the blackboard, the young man screamed happily and laughed.

Accumulating knowledge and spells about magic, and giving oneself something powerful to the devil is called the "book of magic." A magic guide in the shape of a book that gives the reader the power to surpass human intelligence, at the cost of inviting great disasters.

Xiandu Mu Ah Ye, copied those magic books.

She doesn't just write words. Even the magic and curses contained in the true magic book are fully recreated. This is the special ability of the sendu Mu Aye, known as the "witch of the secretary".

And now she uses Nangong's memories of that month as the basis to resurrect the most evil magic book that has completely disappeared - the "Secret Oath". The words that Ah Ye wrote on the blackboard became part of the new magic guide book, spitting out a huge amount of magic. Nowadays, ordinary people say that they can't even look directly at the blackboard when they touch the blackboard.

Now the whole school building of this Caihai School Park is the "secret oath" itself.。

However, the young man who escaped from prison still stared at the blackboard nonchalantly.

"Will you get in my way?"

Glaring at the young man, Ah Ye asked. Floating gently behind her was a knightly phantom in dark armor. The huge sword it drew pointed straight at the young man's eyes.

"Nope. Because your 'experiment' may be unexpectedly meaningful to me. ”

The young man grasped the tip of the sword pointed at him with his bare hands as if nothing had happened. At this moment, the figure of the dark knight blurred and distorted.

Youth did nothing. He just touched it lightly. It's just that this shakes the existence of the witch's "guardian". Ah Ye put on a look of resentment, causing the Dark Knight to retreat.

"That's right...... You...... Thou art the ...... of the Lion King's organs"

Squinting at the fire of the calamity, Ah Ye stared at the face of the young man hidden under his glasses.

The young man carried the witch defenselessly. Just walked out of the classroom.

"I wish you a successful 'experiment', Xiandu Mu Aye. I hope you have a great night of feasting—"

Finally, the young man disappeared into the darkness.

Ah Ye, who was left here, was so angry that he crushed the chalk in his hand. Immediately, with white (bai) powder remaining on his fingertips, he wrote the text on the blackboard. Write the last word in order to complete the secret affidavit.

The secret affidavit to become a complete body was initiated.

And then the erosion of the world began.

The witch, dressed like a god of death, burst out laughing.

At this moment, the "Demon Special Zone" began to collapse-

……

The freshly baked pizza on the table exudes an enticing aroma of cheese.

Although it is a frozen pizza that has been bought for a long time, it can be said to be a big meal for a hungry stomach. Since Fukamori almost treats this as a staple food, this guest room is often stocked with plenty of frozen pizza.

"If only you were really going to die......!"

Sayaka said as if she was spitting out the pizza as she grabbed the pizza with her hand and put it in her mouth.

In front of her cold gaze, she sat the ancient city that was rapidly sprinkling olive oil. And Yukina showed an awkward expression and stared at him like this.

"yes, it's a bit ...... this time."

"You think I want to!"

The heads of the ancient city are covered with black lines. Helplessly looked at the two demon attacker girls sitting opposite.

However, Saya Hua ruthlessly attacked the ancient city again with his sharp words.

"I said you, because of your physical exhaustion, your body is too tired, and you faint!? If you fell down for that reason, make it clear before you fall! How dark are you!? ”

"I can't help it! Not only does the wound on my chest not heal, but as soon as I use my magic, it causes severe pain and robs me of my physical strength. ”

"It doesn't matter what happens!"

Sayaka looked at the ancient city with an annoyed expression.

"But it's nice to get things over before they get any more troublesome than they are now."

"Sort of."

Wattola didn't know where to go to hunt the criminals of the 'Prison Enchantment', and she and Yuma were also seriously injured, and as for that month, she was not only seriously injured, but she was also cursed by Sendu Mu Aye, and she also lost her strength and memory. He is still in a coma.

But fortunately, at least for now, as one of the few aces, he at least has the strength to fight, if even he loses his combat effectiveness in this situation, there is really nothing he can do!

"That's... Senior's ...... You okay? ”

Yukina sighed and looked at the old city.

"Nope." Gucheng shook his head, "By the way, why are you wearing a nurse's outfit on Yukina?" ”

"That's, that's because, aunt...... No, Miss Fukamori said that if you want to enter the laboratory, you have to change to this ......"

Yukina shy lowered her head and whispered. Indeed, the blue apron dress she had worn earlier had become tattered in several successive battles. From the perspective of hygiene, it should be said that it is a more appropriate choice to change into a nurse's uniform. But maybe it's because of the clothes that she can't wear, so it's hard for Yukina to calm down.

But if it's that woman, she probably just wants to take advantage of Yukina's change of clothes to peep.

As long as I think of this, the ancient city feels helpless.

"Sure enough, it's still weird,......"

"No, it's a good fit."

Yukina, who has a pure personality, is simply perfect for wearing a nurse's uniform.

Of course, Saya nodded wordlessly in agreement. She stared at her as if she was going to lick Yukina's whole body, her breathing was a little short, almost making people think that if the ancient city was not there, she would have knocked Yukina down now.
