Demon Lords’ Invasion
Demon Lord Milim Nava, Devil Grucius, and Devil Myulan observed the city Tempest from above while discussing their next move.
Devil Grucius sighed mentally.
“What a terrible person Milim is! Any mistake while interacting with her could lead to a great disaster.” He believed this fact with his entire being.
After staying with her for a while, he realized her complete lack of dishonesty. She is honest to an extreme.
While this doesn’t apply to high ranking demons, most other monsters have no problem telling small lies.
However, Demon Lord Milim probably hasn’t even heard the word “negotiation”.
Originally, Grucius had intended to observe the situation while hiding his identity as a high ranking devil.
Now then, how should he proceed..?
Devil Grucius was desperately thinking of a way out.
Devil Myulan did not see any chance of this mission succeeding.
She is, after all, a demon lord who focused on strength, so her complete incompetency in espionage makes her a hindrance.
And besides, since Demon Lord Clayman failed to hold her back in the first place, he has no right to complain! She thought.
He should have lived up to his nickname and manipulated her despite the fact that she is a fellow demon lord.
She noticed the identically troubled look on Grucius face, and they locked eyes for a second.
At the very least, unless they had Milim work independently, she would definitely impact their mission.
Seems like a number of oni served the mysterious masked monster.
Since Grucius would probably be moving with this objective in mind, Myulan decided to offer her support.
Let Grucius do as he please and observe the situation. So she decided.
If the ripples are too great, the devils will also stand out.
Thus, Myulan decided her plan. Now, to realize it…
Milim observed the city that spread beneath her.
The term High ranking monsters refers to those that have developed intelligence, and depends not on their strength. She understood the extent of their cooperation with a single glance.
How wonderful. Though it’s hard to believe, but they are all named monsters.
She felt her amazement and astonishment overtake her.
Demon Lords like her tend to hate seeing their power disappear like that.
If she seriously made her move, not just Frey, but also Karion and Clayman would answer with great indignation.
But she was truly glad that she had come.
The castle that Milim resides in, in comparison, was built by humans. Who worship her as some deity.
And thus, the land became hers.
This time as well, she didn’t come searching for new subordinates. Rather, she came to kill some time and to later see Clayman and Karion’s upset faces.
She had intended to let them have whoever once she finished teasing them, but…
The monsters living here were of such high quality. Their abilities so great.
Her simple mind has by now completely forgotten about Clayman and Karion.
Someone who’s magic energy rivaled that of a demon lord!
And thus, she made her move.
After deciding to sell medium grade medicine as the city’s specialty, we continued researching towards mass production.
And then I got an idea, could the difference in purity be due to oxidization?
The only difference is that one occurs in an oxygen rich environment whereas the other is inside me.
It seems that this world knows of chemical elements. Though, included among the different types of magic, in opposition to spirit magic, it is called chemical elements magic.
“Is it affected by oxygen?” He said he’ll consider my hypothesis.
Success is built upon many failures. A mistake can also be considered progress.
Kaijin is busy discussing something with Bester. They are so friendly right now that it is hard to believe their earlier animosity.
I returned to the city using a magic circle.
We set up the city’s magic circle near the gates.
Bester, however, insists that it is impossible.
So I’m probably just worrying too much. Just using something I know nothing about, albeit hesitantly.
I should learn magic soon…
Then, the moment I had intended to head over to Rigurdo’s place to let him know about our success,
Dangerous! I made the split second decision and ran beyond the gate towards it.
Extremely quickly, too.
Steeling myself, I observed the opponent.
A beautiful girl. Blond hair tied into twin tails with a black Gothic dress covering her body.
The lump of magical energy, or rather, the girl landed right in front of me.
Though she was flying at such terrifying speed she was able to erase it completely before landing.
Now, however, was not the time to consider such things.
「Pleased to meet you! I am the Demon Lord Milim Nava!
I came to greet the strongest being in this city!」
The beautiful demon lord told me.
A demon lord!
Shouldn’t your subordinates or some four heavenly kings to show up before you!
However… how should I respond.
I’ve gotten pretty good at magic energy manipulation recently, so I can subconsciously prevent any leaks.
Whether I check with a clone or through 『Magic Perception』I don’t seem any different than a normal slime, that’s how well I’ve hid my aura.
Even then… I wonder how she saw through me.
「The pleasure is mine… I am the lord of the city, Rimuru.
You seem to have seen through to my true strength, huh?」
Though perhaps the strongest one around here is actually Hakurou. Though I won’t say that.
While observing her, I asked that question.
「Fufun! That kind of thing is simple for me.
So no one can pretend to be weak before me!」
So eyes with analytical abilities?
Her proficiency level is beyond question higher.
If we fight, I might have to use all my skills and tactics just to create an opening.
Her level is completely different from the pseudo-demon lord that Orc Disaster was.
「What amazing eyes, you have. Now, what would be the purpose of your greetings?」
Let’s hear her intentions.
Knowing your opponents goal is absolutely necessary, after all.
「Mu? Purpose… you say? Just to greet you, though?」
「…」
She’s hopeless.
Just a greeting, she says! I’m honestly at a loss here.
「Ah! Right, right, I remembered!
You, how about calling yourself a demon lord, and becoming one?」
She suddenly added.
The hell she saying…
「Eh? Why would I want to do such a troublesome thing?」
She was the one to be surprised now.
「Eh, I mean, a demon lord! Sounds cool, right? You long for it, right?」
「… Eh?」
「Eh?」
Seems like there’s a fundamental difference in our thought process.
We’re just staring at each other faces without having our opinions reach the other. Well, a slime doesn’t have a face, though.
「Well, then, let me ask. What’s so good about becoming a demon lord?」
「Nah… I have no need for that. Not interested.」
「In a bunch of ways… if I were to become a demon lord, are there other ways to have fun other than to fight?」
「Then isn’t it really boring?」
The moment I said that, Milim appeared as if she were struck by lightning, and looked as if she took serious damage.
My words were so accurate that she can’t say anything in response.
I should take advantage of her shock to take my leave.
「Well then, since we got that out of the way, could I ask you to leave!」
I handled that pretty well, I thought…
「Wait! Y-you! You’re doing something more fun than being a demon lord, aren’t you!
I’ m mad. Teach me! I won’t forgive you if you don’t!」
I should be the angry one!
The opponent is a demon lord, angering her would be bad.
At times like this, just have to be straight with her.
Let’s imagine her as a relative’s kid.
「I got it, I got it. I’ll teach you!
From now on you’ll call me Rimuru-san!」
You should be calling me Milim-sama!」
「…」
And you will call me Rimuru. How about it?」
I allow you to call me Milim.
「Ah, is that so. Then let’s drop formalities from now on!」
Some sparks flew between us during the conversation,
But we seem to have settled on dropping formalities entirely between us.
「Okay, I’ll guide you in, then. But don’t go wandering on your own, okay?」
「Good good! Aren’t you obedient. Also, don’t go rampaging in the city without my permission, okay? If you can promise me that, I’ll consider you my friend!」
「That’s easy! I promise, Rimuru!」
So far so good.
Monsters have to keep their promises, right?
Should be fine then. Thinking that, I led Milim into the city.
Accompanied by a slime, Demon Lord Milim entered the city.
And bewildered by this fact,
「Hey, is Milim getting a head start on us?
「So it seems. But this is for the best.
「Right. Let’s just pretend we got rid of a bothersome person.」
They said nodding to each other.
And now that this happened, they can move freely.
「So, what will we do? How are we going to infiltrate?」
「Yeah…」
While the two were busy considering this, Grucius’s “Far Sight” picked up a human squad approaching the city.
「Yo, a human squad! Are they here on monster extermination?」
「Probably… but do they know that monsters built a city here?」
And looking at each other,
「Let’s mix in with them?」
「That’s a good idea. We’ll disguise ourselves as humans and infiltrate the city!」
They decided.
And after some light preparations, they mixed in with the squad moving towards the city.
And thus, the two were able to meet the human named Youmu.
