The netherworld.
The realm where demons live.
And the king that rules over the netherworld is...
the Demon King.
But ever since the previous Demon King, Derkila, disappeared,
the Demon King's throne has been vacant.
Who will be the next Demon King?
The One Who Rules Over the Netherworld
"The One Who Rules Over the Netherworld."
I'm done!
Suzuki Iruma, age fourteen.
He is a human, but he goes to the demon school Babyls in the netherworld.
Well done, Iruma-sama.
Thanks, Opera-san.
Babyls is currently on end of terminus.
End of terminus is similar to what we call "summer vacation" in the human world.
Iruma was doing everything he could to finish his homework toward the end.
I was worried about all the extra homework we got, but...
That truly seemed like something Kalego-kun would do.
Yeah...
Why did he get so much extra homework during the end of terminus?
Let's rewind a bit.
A competition?
The team who has the most fun wins!
And the teachers will treat the winning team to something!
Don't make your own rules, you fools!
Very well. I will allow a prize...
And the losing team will get double homework during their end of terminus.
And then, at a certain restaurant in town...
In my eyes, the winner of the team fun times competition at Walter Park is...
All of the teams!
And, by the way, this is your treat, Kalego-kun.
Hell yeah!
Let's eat!
I will definitely not hold back!
Thank you, Sensei.
Eggie-sensei's got deep pockets!
This is so good!
I'm so happy for you, Iruma-sama.
Excuse me!
I'd like to get another order of everything from here to here!
Are you sure you're going to pay for everything, Kalego-kun?
I'll be happy to pitch in.
Oh, I don't mind. If all of them won...
that also means they're all in last place, too.
The teams in last place get double the homework,
if I remember correctly.
Huh?
H-He pulled one over on us!
Th-Th-That's awful!
We've been deceived!
Wow...
Kalego-kun...
Malicious!!
I'm so happy I finished in time.
Yes.
The end of terminus is coming to a close,
so you will need to get ready for the new term soon.
Precisely!
I'm pretty much done with all my work, and now you're done with your homework.
We finally have time!
Okay, let's go.
Huh?
W-Wait! Go where?
Wh-Where exactly are we going?
You're going shopping with your grandpa for things you'll need for the new term.
Shopping?
Oh, right. Iruma-kun, you'll need a disguise.
Huh?
Well, you're a celebrity, so you're going to stand out!
Detection-warding glasses!
Oh, you look so good in glasses!
Now you won't be recognized, and you won't have the press hounding you.
We'll be able to shop in peace.
Yeah.
I'm going shopping with Grandpa... This is my first time.
I wonder where we're going.
Sullivan's mansion is near Babyls.
Nearby, there's the dormitory where the teachers live,
a park, and a shopping district where you can find all kinds of goods...
Magical Street.
Wow!
There are so many shops here!
This is Magical Street.
Sullivan-sama!
Hello, everyone. How have you all been?
Grandpa sure is popular...
Sullivan-sama! I saw your press conference on TV!
Your grandson is amazing.
Your grandson isn't with you today?
My grandson's such a wonderful lad.
I couldn't be prouder.
Are you one of his attendants?
Y-Yes.
These detection-warding glasses sure work wonders.
That looks very good on you, Iruma-sama.
Y-You think so?
We'll probably need to get you a few winter coats.
I'd recommend some Devia ones.
They're very well made, and you can get your wings in and out so easily.
I'll take everything to the left of this.
Oh, thank you so much!
Wait, wait, wait!
That's way too many!
You can have one for every day of the week.
Hats and horn ornaments are in right now!
Iruma-sama, how about this?
It's a collar that makes your familiar even more obedient.
Huh?!
Shall we get it?
I-I don't...
Hey.
Hey!
He—
That's okay.
I see.
There are so many books.
I'll need The Basics of Magic, Camiden's Biography, The Secrets of Magic...
Right.
Yes, yes.
Yes, yes, yes.
How about a copy of The Demon Lord's Prophecies for Dummies?
I'll take it!
Thank you very much.
That many?
Once your new term begins, you'll have more spells to learn
and more opportunities to use them.
We'll have to practice magic a bit more.
You learned Fractal in class, right?
Weight Adjustment (Fractal)
Well? Can you use it now?
Y-Yeah.
S-Somewhat— Huh?!
If you master it a little better, you might be able to fly.
I'm sure you'll need to practice quite a bit, though.
Oh, right.
My senpai in the student council also told me to practice magic.
I'm gonna practice more!
You just have to get used to it.
Once you can modify it a bit better...
Whoa, wh-what?
It comes in very handy.
Tsk, tsk, tsk. Shoplifting is bad, my friend.
Hey! He made the books smaller!
We're handing you over to the Demon Border Control!
Get over here! Walk!
Damn it!
Grandpa, you're amazing!
Really?
Thank you so much, Sullivan-sama!
Iruma-kun complimented me!
As a token of our gratitude, we'll give you a discount!
Sullivan-sama is amazing.
But I wonder why Sullivan-sama still hasn't become the Demon King.
Yeah, he's a Tet and the top candidate for the next Demon King.
Yeah.
Iruma-kun.
Come on, we're off to the next shop.
Oh, sure.
It's so cute.
Mogurin.
It usually lives underground, but loves snuggling in clothes, too.
Click, click! Click, click! Click, click!
Hey, that tickles!
The Black Goat Notebook. Very durable.
This is an anti-drowsy pen.
How does this keep you from getting drowsy?
If you seem drowsy, it bites you.
Rawr!
Infinipop!
You can lick and lick and it'll never go away.
Whew, what a haul.
Right?
Yeah.
Thanks, Grandpa. I had so much fun!
Now you're all set for the new term.
Everything was so new that I didn't know where to look.
I'll go get the carriage.
Thanks.
You've gotten pretty used to the netherworld.
Iruma-kun.
Are you having fun at school?
Yeah, I'm having lots of fun!
I see.
The new term should be a lot of fun, too.
There are a lot of events, so it'll be exciting.
New Term
The first term was basically like an orientation.
Huh?
I-I remember my days being rather intense...
I guess they were for you and your friends, for some reason.
So there's going to be even more?
Your new term might end up a bit chaotic, too.
Oh, yeah. Grandpa...
Yes?
How do you become the Demon King?
Pardon?
Sure
Long Ago...
Long ago...
665th Floor
Such an intense aura...
The Thirteen Crowns are here, and yet...
Where did our master go?
The Demon King has disappeared.
Derkila-sama.
This is no good.
Sullivan in His Youth
I told you today was the Thirteen's Dinner with all Thirteen Crowns present.
Yeah, yeah.
I know.
The Missing Demon King Derkila
Well, if you knew, that's even worse.
Derkila-sama, you could at least—
Shut up.
All of them just lining up there together...
Do they really think they can run the netherworld from some desks?
It's right here!
This is the netherworld I created.
All right.
Summon those Thirteen Crown fools here.
We're going to have our meeting here.
Are you sure it's not because you just don't want to move?
You're ruthless, Sacchan.
Just look at this view! This is the netherworld I created!
Am I right,
Sacchan?
Grandpa.
Sacchan.
Grandpa! Grandpa!
Are you okay?
Er, you just startled me a bit.
Startled you?
But...
To think that you want to become the Demon King!
Huh?
You should've said so earlier!
Wait, wait, wait! No!
It's not that I want to be the Demon King!
It's just that I heard some demons talking about the Demon King when we were in town.
They were saying you could become the Demon King, but you haven't.
So I just wondered why...
and what exactly it takes to become the Demon King.
Ah...
I see.
You know about the Thirteen Crowns, don't you?
Y-Yeah.
Opera-san said they are the heroes who represent the netherworld.
You're one of them, too. Right, Grandpa?
Indeed.
Each of the Thirteen Crowns has been around since the age of the Demon King
and each has important responsibilities.
Peace exists in this world because the Thirteen Crowns are at its center.
In order to become the Demon King, you would need the trust of all thirteen.
All of them?
Basically, it's a devi-important responsibility.
The Demon King is the pinnacle who rules over all of them, after all.
Wow...
So the Demon King is in charge of most of the netherworld.
That seems like a lot of work.
No, no. Not "most."
It's all of it.
Because the Demon King is the netherworld itself.
Even if the demons of the netherworld talked for decades
and decided to go right,
if the Demon King said...
Go straight.
They would then
create a path that didn't exist.
And...
They would create a river in the sky, create a flower field out of magma,
and create the netherworld in his vision.
The Demon King is the world. Sublime and absolute.
So, yes...
Looking at the current netherworld...
you can probably imagine what kind of demon the previous Demon King,
Derkila, was.
He must have been a very fun demon.
Mm.
So I may eventually be able to become the Demon King.
Even if I become the Demon King, I'm not sure if I could live up to the title, but...
It would probably look like this!
Iruma Buns
Grandson Buns
Iruma Street
Welcome to My Grandson's Town
Iruma
My Beloved Grandson
Grandchild Juice
What?!
Of course,
I would personally love to see what kind of netherworld you would create.
And I would support you with everything I have!
I would do anything necessary!
Grandson
Hurray! Hurray! Iruma-kun!
No, wait! I don't...
Well, let's head on home.
Oh, sure.
Sorry to keep you waiting.
If I were the Demon King...
And so, we're all prepared for the new term!
You're going to laze around the house with your dear old grandpa for the rest of end of terminus!
You still have quite of few of your usual duties to tend to, sir.
And that's why Gramps is going to laze around and
spoil Iruma-kun to death and play while doing my duties!
You just said you were going to play. You may not.
Opera, you meanie!
Once the new term starts, there are going to be more events, and I'll be busy!
I don't want to be apart from Iruma-kun!
I want to stay with him forever!
You want to laze around with your dear old grandpa until the last day, too, don't you?
Huh? Uh, sure...
The new term...
He did say there are going to be a lot of events. I'm excited!
The Demon King Prophecy Scroll...
"He shall make one and all his servants...
He shall form blood pacts and heal all demonkind.
He shall descend from a foreign realm
and wear the golden Ring of Solomon on his right hand."
The Demon King...
The Demon King, huh?
If... If I were to become the Demon King...
I wonder what kind... of netherworld...
I'm Suzuki Iruma, age fourteen. I'm a human.
I drew a lot of attention to myself after the mess at Walter Park,
so I'm going to spend the rest of my break quietly.
Good work.
Spend my break quietly...
I've got you!
Spend my break quietly...
Sit down now.
You made me horf all of that mana,
and you sure seemed to be enjoying yourself afterwards, L'il Iru!
You sure were getting cozy with someone!
Cozy?!
You have some nerve! After all the suffering I've been through!
When did you turn into such a rotten child?!
Honestly, what do you want me to do?!
I-I really am doing my best!
Oh? Oh, really?
Yeah...
Today's the first day of the new term!
Grandpa! Opera-san! I'm heading out!
You look great in your new outfit, Iruma-kun!
Have a wonderful day.
You'll be going, too, sir.
I know!
Good morning, Iruma-sama!
Iruma-chi, good morning!
Good morning, Azz-kun and Clara!
Let's go!
Yeah!
Indeed.
Our homework sure is heavy. Vroom, vroom.
It sure is.
I'm Suzuki Iruma, age fourteen. I'm a human.
I shall carry it for you.
I'm fine.
But...
I go to the demon school Babyls.
Today's our first day of the new term!
Humans only exist to be our food
Suck them dry, soul, blood, flesh, and all
Tremble at the sound of black wings as we take flight
For we are demons
As this song pours forth from our red lips
Scream for us, for we are demons
We strive to strengthen our evil tendencies in our fortress
Its name is Babyls
A school in a league of its own
Give your soul, blood, flesh, and all
May we strive to achieve the pinnacle of the demons
Today is the first day of your new term.
Right.
Indeed.
Right.
Babyls special class order!
It's so loud!
The Misfit Class must all become Dalet rank before becoming second-years!
Dalet is the borderline rank right before graduation.
To require first-years to achieve that rank is abnormal indeed.
If you fail this order, you will immediately be ejected from the Royal One!
What?!
Will Iruma and his friends be able to avoid being thrown out of the Royal One?
We will tell you that story another time.
