Oh....

　When we finally stepped into the undersea labyrinth, we were groaning.

　We thought it was a dimly lit cave, but it was as bright as daylight inside.
　A type of algae called koussou lit up the labyrinth.
　It was also stuck to the walls and ceiling of the cave.

　As a result, the cave was illuminated even in places that did not get much sunlight.

　Furthermore, small spirits were floating here and there.
　Perhaps it was because the magic power was strong.
　Perhaps the tide has created a pool of magical power here.

　But that doesn't seem to mean that it was created naturally.

　There's a part of it that clearly feels like an artifice that seems artificial.
　I activate the [Mapping] magic and scan it.
　It seems to be quite vast.
　Even with my magical power, there were many obscure parts.

　Accompanying me, Cecil, Rowan, and Sarasa, plus the magician duo of Mattelus and Mucha.

　Unfortunately, we left Sheila behind.
　It was to get her to lead the nearly 600 students we left behind.
　If something happens, Sheila will be able to handle it to some extent.

　The people to be selected are Cecil, Rowan and Sarasa, who are familiar with the dungeon.
　And I brought Mathels and Mucha, who are the targets of my surveillance, with me.

''It's kind of exciting to be in an unknown dungeon.

Cecil.... Didn't you catch Lacelle's disease?

Hmmm. But it reminds me of the first time I met you, Lacelle.

　Sarasa laughs.

　Perhaps she was referring to the dungeon that had been a goblin's nest.

'It was there, hey, I miss it.

　Cecil nodded sincerely.

'What's up?　I thought you were going to observe our work?

　It was the captain of the magician's unit.
　He gave her a sharp look.

'Cut down on your private conversation, lass. This is a dungeon.

"Okay, okay. I understand.

Just one 'yes'.

Yes. Okay.

　Cecil complied.
　The troop leader stops in his tracks and starts walking again.

　Cecil scratches his red hair.

''Already.... It's hard to do.''

'I don't mean to contradict you, but you talk too much, Cecil. Like you said, this is an unknown dungeon. Your voice can be a trigger for something.

Oh!　To Lacelle.

Hey.

　The troop leader turns to us again and glares at us.
　Seeing Cecil cover his mouth in a hurry, the troop leader walks away.

''Looks pretty spacious. Alright......... Let's divide up the troops. The students should be divided into two groups as well.

　Instructions.
　I raised an eyebrow.

'Troop leader sir. How about splitting up the troops now........ Wouldn't it be better to distinguish the structure of the dungeon and the type and number of demons inhabiting it first?

"Lacelle Gilell Stark. Who are you?

　I'd like to tell him that he's a guest.
　But it doesn't seem to be in a joking mood.

　I decided to respond honestly.

I understand. Let's split up the group.

That's it. Follow our instructions.

　I'll divide the six of us into two groups.
　In my pair, I have Salasa and Mucha.
　In the other, I'll have Cecil, Rowan, and Mathels.

　Mucha, in the same group, overhears me saying, "Isn't it strange?

''Isn't it strange, senior Lacelle?

You're trying to thin our ranks. Watch out for your group. They're up to something, you know.

All right. I'll be careful.

　Cecil nodded.

　What I'm worried about when it comes to this is the students I left on earth.
　No, I don't care about the students, but I'm worried about Sheila.
　I hope she's not reckless........

　Then we also part ways with Cecil and accompany the troop leader's group.

　The first one to react was Mucha.
　Mucha, who had [Detection] activated at all times, notices a presence coming towards us.

　The magician (wizard) troops, who are all [mages (wizards)], are slow to respond.
　He readied his staff and put his magic power into it.

　Oh, come on.
　You're jumping to conclusions.
　We haven't even decided on a magical beast yet.
　All that magic we worked so hard on is going to go to waste.

　Oh, I get it.
　Are these guys not used to dungeons?

　Upon closer inspection, the faces of the troopers were somewhat drawn.
　Sarasa and Mucha were much calmer than they were.

　There was an echo of the ground.
　As expected, it was not the sound of human footsteps.

''Senpai, this one is also in combat readiness.

Not yet. Sarasa....

Yeah. I don't have all the information yet, but I'll try.

　Sarasa activated her magic.

　[Future Vision]

　It was Sarasa's eighteenth.
　As the name implies, he looked to the future.

　In the meantime, footsteps were approaching.

''All right, Lacelle-kun. Probably a golem-type demonic beast is coming.''

The Golem type?　I see. That girl can use [Future Vision]?

　The troop leader prepares to activate lightning attribute magic.
　Golem-type magic is difficult to use.
　However, if the amount of magic in the lightning attribute system magic is high, it can load up the core inside at once and crush it.

　If the situation is that all of us are 【Mages (wizards)】, then it would be possible to wipe out the golems by hitting them with a high magic amount of magic.

　However, I'm not ...

''It's better not to do that.''

What?　Lacelle, what did you say?

I said it was best not to.

Who the f*ck are you?

　The troop leader glared at me again.

　But I cower my shoulders.

''Well excuse me. If you go that far, I won't say anything more.

　I decided to keep quiet.

　The magic power of the magic unit increases.
　The moment I saw a shadow that looked like a golem, the troop leader shouted.

"Let go!

　[Thunderbolt Blade]

　A blue-white light was emitted on the golem all at once.
　A tremendous, grating sound shook the ear folds.
　The light pierced the golem.

　--It looked like.

''What!''

　The squad leader's shout echoed.
　The lightning attribute magic that was released came back to us.
　One after another, they attacked the magician's unit.

''Gyaaaaah!

　The screams of the troopers echoed.
　Naturally, so did that troop leader.

　Oh dear.........

　That's why I warned you........

　I thought it was the height of folly, but I knew I had to help her.

　I waved my arm in the air.
　All the magic in the air was blown away.
　The lightning attribute magic, which has lost its energy source of magic, will disappear at once.

It's a good idea to have a good time. Did you........erase the magic?

　The troop leader muttered while half-unconscious.

　It seems that thanks to the fact that he immediately erased the magic power, he was only slightly injured.

　I activate the [Cleric] magic.

　[Recovery Squad]

　It is a spell that increases the regeneration ability of a person within a certain range.
　It's one of the most advanced forms of magic.

"Nonsense! You're the only one who can raise the level of advanced magic.... A child....

It's a ruby golem, sir.

What?　Ruby Golem!　Isn't that an S-ranked demon!

　Yes.
　Its characteristic is that it has a body surface that reflects magical power.

　Eventually, that ruby golem will appear.
　The magical unit was horrified by the strange figure.
　It looked as if its entire body was covered with jewelry.
　Although it had arms and legs, no organs such as mouth, nose or eyes could be seen.

　Even so, it walked on two legs and waved its hands as it came towards us.

''Nonsense!　How could an S-ranked demonic beast be in this undersea labyrinth!

Because it's an underwater maze.

What?

''It's only because the labyrinth wasn't manned that they survived without being hunted. There's a lot of magical power here, and it's the perfect place for an S-ranked demonic beast to live.

　The older and less man-made dungeons were more likely to have high ranking demonic beasts surviving.

　The dungeon in the fifth branch would be the best courtesy.

''Well........''

　I step forward.

Where do you think you're going?

　The effect of lightning attribute magic?
　The troop leader still had difficulty moving one fingertip.

''Where?　I'm not going anywhere.

　It's just...

　I run.
　I pull the sword from its sheath and let go.

　At that moment, I activate the magic.

　[Degeneration]
　[Object acceleration]
　[Muscle mass strengthening]
　[Acceleration]
　[Fatal]

　I activate quintuple.

　The enhanced body and blade were sucked into the fragile part of the ruby golem.

　Kyin!

　At that moment, countless sword flashes shone on the ruby golem.

''Vubobobobobomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomomom!''

　I emit a sound that is neither scream nor howl, and it shatters into pieces.

　I sheath my sword.

''That's great, Lacelle-kun.
Well done, sir.

　Sarasa and Mucha greet me.

　Meanwhile, the troop leader's eyes widened and he froze.

''Oh no........a single blow to an S-ranked demonic beast.......''

'Nothing much, sir, nothing to worry about, troop leader. Now, please stand up.

What?

Continue exploring the dungeon, sir. I'll ask for an escort, troop leader-dono. After all, this is our guest(s).

　I grinned.
