The center of Latesia.
　It is known as a dangerous area where a large amount of magical elements drift and powerful demons roam.

　In such a place, a jet-black castle sits as a matter of course.
　It was created by a single demon, a majestic building of demonic steel.
　It's an overwhelming, evil castle that overwhelms all who see it.

　Anti-magic, anti-intruder wards, and powerful demons blocking the entrance.
　Countless dragon species were flying around in the sky covered with dark clouds.
　The impregnable demonic castle is impregnable and difficult to approach, even if humans lead an army.

　The name of this evil castle is "Demon King's Castle".
　It is the base of the Demon King's army led by the Demon King Ortegia van Zalefeld.

　The Demon King's Castle is a type of labyrinth.
　There is a huge labyrinth core inside, and it constantly releases magical elements into the castle's surroundings.
　Therefore, a large number of demons inhabited the perimeter of the castle.

　A room in the Demon King's Castle.
　Several demons were surrounding a long desk and were face to face with each other.

　There was a somber air in the conference room.

　A few days ago, a corner of the labyrinth that had not been threatened for thirty years had fallen.
　It was decided that a meeting would be held to investigate the cause and take countermeasures, but that day.
　On the day of the meeting, the news arrived that the Purgatory Labyrinth had fallen following the Abyss Labyrinth.

　The meeting was held because they couldn't afford to lose the labyrinth any more, though.

''In the end, isn't that why the Earth and Fire Demon Generals were such goofballs?

　The one who said this was a man of the demon tribe dressed in a jet black military uniform.
　It's a good idea to be able to have a good time with them.
　With his slender body, he gives the impression of a kind man at first glance.
　But there was contempt in his eyes, and his mouth was twisted with a sneer.

''I'm not like those guys, you know. I don't want the other demon race to step in on me.''

　Raising his chin and glaring at the assembled demon clans, the demon man continues to speak in an irreverent manner.

''I am ......, but with Ortegia-sama's absence, we cannot tolerate any more blunders.

　The one who spoke back to the words of the man of the demon race was a demon race with blue and silver hair and indigo eyes.
　"Lefise Gregoria, the Rain.
　A demon tribe that has been entrusted with acting as the demon king in the absence of the demon king.

"To begin with, it was you who appointed the Earth Demon Generals and the Flame Demon Generals, wasn't it?　It's your fault, isn't it?
............

　Even in the face of the Acting Demon King, the man of the demon race - Dionis - does not lose his irreverence.

　A situation in which two labyrinths had fallen.
　In order to defend the other labyrinths, Lefeez proposed strengthening the labyrinths.
　However, Dionis cut it off as unnecessary and discarded it.

''But, Dionis-sama. The imperial army is making a disturbing move. I'm also worried about the brave men who are said to have been summoned in the kingdom and ...... wouldn't it be better to strengthen the labyrinth here?

　At that moment, the demon girl standing behind Dionis opened her mouth.
　She is Dionis's subordinate and is in charge of miscellaneous tasks.
　It's the girl who is a mixture of human and demon.

''Oh, I see.''

　Turning around, Dionis turns around and smiles kindly.
　Immediately after that.

''Ga--, bah!''

　The girl's face was covered by a sphere composed of water.
　Deprived of oxygen, the girl scratches her algae while her eyes are black and white.
　But no matter how much she moves, the sphere does not disappear from the girl's face and continues to block her breathing.

'Look, who allowed you to talk back?　Do you think you're allowed to talk back to me as a lowly scum?

　The girl opens and closes her mouth and tries to say something, but the water prevents her from being heard outside.
　The girl's face gradually turns red and then blue.
　Dionis was watching this scene with deep enjoyment.

''--It's unbearable to watch.''

　At the same time as the voice, something shimmered and fell to the ground, losing the sphere that covered the girl.
　The soaked girl crumbled to the ground, coughing vigorously.

''Isn't that one of your men?

　The blue-haired man who had been sitting silently on the seat beside Dionis.
　I'm sure you'll be able to find out more about this in the next few weeks.

The first thing you need to do is to get your hands dirty.　That's why I'm at my disposal.
'...... It's offensive. It's repulsive.
Yeah, I'm sorry about that.

　Ignoring the unapologetic apology, "Distortion" called out to the crumbling girl.

'Hey, girl. Anyway, out of the room ----
I...

　"At the same time as Distortion called out to her, a sword suddenly appeared and pierced the girl's face.
　It's not just a matter of time before you'll be able to get your hands on it.

"...... me.
I cleaned it up for you because you said you were uncomfortable, remember?　Oh, I'm sorry!　I'm sorry! Are you in her mix, too?　Do you think I felt sorry for you?
Well said. Is that what you mean by "please kill me"?

　And that's when both parties got wind of each other's reactions.

That's enough!

　Then Lefise interrupted him.
　The energy is so great that everyone present is under the illusion that the temperature in the room has dropped.
　Dionis slumped back in his seat grumpily and "Distortion" fell silent.

　Lefise continued to force the meeting.

I understand. Your labyrinth is untouched. We'll see about that. However.
...... I know, you don't have to tell me.

　With a smirk and a seemingly innocent smile, Dionis nodded.
　In response, Lefise announced.

''At ......, this meeting is adjourned.''

You're not going to be able to do that.

　Inside the conference room where the other demons had left.

　The sound of a woman's laughter could be heard.

　A giggle that reverberates throughout the room.

"...... What's so funny, 'Lucifina'?"
No, I just thought you were the same.

　A "half-elf" woman who had never opened her mouth before.
　She has shiny golden hair that seems to shine like a bundle of sunshine and silver eyes that give the viewer a sense of compassion.
　Unlike other demons, the woman wears a loose dress.

''So, what are you going to do?　Aside from the imperial army, I heard that there are brave men working on it, just like that idiot?
No, I don't.

　Dionis answered Lucifina's question.

'Just kill them.'

　Lucifina giggles at the answer.

　A labyrinth set up in the Empire.
　Guardians of the Dead Swamp Labyrinth ----,.

Just like that idiot.

　"Water Demon General," Dionis smiled wickedly.
