"The demons create dungeons at Demon Castle when they are twenty years old.

I was muttering such words in the saloon under the Demon Castle.

In the center of the room is a giant crystal with dozens of men and women standing around it.

Some of them have dragon scales and fangs on their bodies and have a human-like appearance,

... It's natural to say that it's a demonic.

From the perspective of myself, except for the small horns that grew on my head, everyone seemed tough.

...... I'm supposed to be the same year.

The hundred people here are the demons who have turned 20 this year.

Demons are long lived and have few children, but this year they are relatively large.

…… In the past, it seemed that the one-digit or Zara gathered at Demon Castle.

When demons reach the age of 20, they go to the Demon Castle to create dungeons.

While living in a dungeon that he created, he would learn how to use the power as a demonic and how to extend the dungeon at a school attached to Demon Castle.

In other words, Demon Castle is a kind of educational institution,

"Now, we will start class screening and dungeon creation!"

Now, that education was about to begin.

A professor at the school, standing next to a giant crystal in the center of the room, began to call this year's students, looking at the roster she had obtained.

"Vampire Demons Sophia Grave! Before"

"Oh, me."

The first girl to call was a girl with thin long ears and black wings.

Her height is not that big, but she looks like a bewitching vampire, with a fairly exposed look and some sort of sexy white skin.

"Sophia. You're ... well, you're a vampire's noble, noble of the Grave family. I'm hoping."

"Thank you, huh .. so why should I touch this crystal?"

"That's right, if you touch this crystal-mother core, a dungeon will be created and registered in the core depending on your ability."

"Well, you live in the registered dungeon while you're at school, right?"

"Yes, but it's a lifetime home that you can use even after you leave the school. So just imagine your castle."

While being told by the professor, the vampire touched the crystal.

At that moment, the crystal shines pale red.

And the red light projects a dungeon map on the surface of the crystal.

"Oh, this is amazing. It's also about making an A + class dungeon with up to ten levels in the early days.

"I was trained at home."

"Hum, let's go to the special advance class."

Everyone in the room is screaming at the words of the professor.

"Suddenly going to the special advance class or this year is the hottest thing?"

"Oh, there are some prestigious aristocrats, but I'm going to make an A-class dungeon for the first time.

I was watching the dungeon map floating on the crystal in the noise.

Creating dungeons is a kind of power test.

If it is strong, it can produce something wide and deep, and if it is weak, it can produce something small and narrow.

Therefore, among the demons, the nobles and royalties that are strong in power make dungeons with A or A + or terrible ratings, while ordinary demons make D or C or other items with moderate ratings.

According to the ability shown by this result, it seems that it will be divided into special advance class and normal class, and what you will learn will change,

...... But it's fine to live in a normal place, so it's fine.

I think it is enough if it is large enough to make four and a half mats.

If it is too wide, it seems to be difficult to move.

While living peacefully in the size of a single house, learn how to use power in a normal class at the school.

And when I thought that I should go back to the countryside and inherit a family pharmacist,

"Next. Chrono Archon of the Majin"

The second time my name was called, I came forward.

The professor looked at this face and shook his head a little.

"Kurono is ... a genius, isn't it a demonic character? ... Half or something?"

"No, it's a normal demons"

A demon who grew up in a countryside with no stranger.

"I see ... Yeah, it was a rude question."

"Well, I'm used to it and don't mind. Unlike the other races, the demons don't have any extreme characteristics."

The only thing that makes you different from people is the horns that grow on your head. There is no way to make a mistake.

"Thank you for saying that.-Well, I'm sorry to take the time. I'm going to make a dungeon. Feel lightly imagining your own castle and touch this mother core."

Even if it is said to be a castle, I can be satisfied enough if I have four and a half mats.

If it's luxury, it can be a slightly larger room.

… Well, what can I do if I can live comfortably?

I'm not that strong and I can do something decent.

I am looking forward to seeing what I can do in a normal class.

With such a light feeling, I touched the crystal. that moment,

"-!"

The crystal turned black at once.

"What?"

The blackened crystal emits black light.

What is drawn is a huge map.

It was filling the whole crystal.

But the map isn't just filled with crystals.

"Nuo !? What is this black light!"

The black light spread out so as to fill the entire room, reflecting the entire map of the dungeon.

"That's a catastrophe !? It's kind of scary ...!"

As a result, suddenly those around the crystal surprised,

"This is--what is going on?"

Even the teacher in front of me was in a hurry.

He is staring around the crystal while sweating cold.

A few seconds later, with a bloody face, the professor spilled words.

"Yunhyaku, Hierarchy ... ??? What's this expansive. A or S-class ...? Not much. This is a legendary demon class dungeon ...!?"

"Yes?"

I can't really understand what he is saying.

What are you saying about the Demon King class?

"Ki, what kind of power do you have ...?! I mean, what did you imagine!"

"No, what a mere demonic demons in the countryside."

And what I imagined was a dungeon that could be a normal home.

I'm not sure what's going on, but

"Anyway, Chrono. Come here! And let's go to the Demon King!"

"Um ...?"

It seems a bit out of my plan to live calmly and comfortably in a four and a half mat room.
