01x09 - The Previous Demon King Is Too Scary!! | The Previous Demon King Is Too Much of a Doting Grandpa!!

Post by bunniefuu »

There was once a demon more terrifying

and evil than Demon King Ahriman.

If someone made him angry, humans, demons,

and entire countries would be

utterly destroyed.

He was considered an

unstoppable living calamity.

The previous demon king, known

as the King of Destruction

His name is Zareth!

THE PREVIOUS DEMON KING IS TOO SCARY!!

"The Previous Demon King Is Too Scary!!"

My father, the previous demon king Zareth,

is about to celebrate

his 10,000th birthday

Yes, Your Majesty!

My father was feared as

the King of Destruction.

If he comes here and

sees Doux like this

Th-That would not be good, Your Majesty.

So you think so, too

I'm terribly sorry!

You've left me in charge

of Lady Doux's education,

and yet, she still remains too kind.

Yes

Doux is just too kind.

If all else fails, please

allow me to take her

on a special trial:

a demon social studies trip.

Demon social studies trip?

DEMON SOCIAL STUDIES TRIP

I will have Lady Doux

witness the atrocities of several

evil demons over several days.

Oho!

Then Lady Doux will be influenced

by the other demons' hearts

and shall awaken to her own evil heart.

A demon social studies trip?

I will have you learn what

exactly demons are on this trip.

This is a special trial just for that.

Special!

These are trapping specialists.

They are called goblins.

It is their job to capture the humans

that we use in the demon world.

Humans will be coming

through here soon.

Try capturing one, Lady Doux.

You can use any method you please,

but you should try beating them to

soften them up for capture.

It's fun.

Goblins are some of the cruelest

to humans out of all demons.

If she sees that, I'm sure the evil

heart within Lady Doux will awaken!

Here they come! Get 'em!

Hurt them!

I'm scared!

Yay!

I caught a human!

Er, good! Well done, Lady Doux.

Again! I wanna do that again!

Next, I'm gonna catch some goblins!

Huh?

Humans! Let's catch them together!

Huh?

Wh-What are you talking about?

We don't have time to

waste on such nonsense!

A FEW MINUTES LATER

Catch them!

Run away! Run away!

Playing is more fun than beating!

They are black magicians.

Black maggie-shuns?

They are demons who use magic

to create calamities and

illnesses to make humans suffer.

We were just about to cast

a spell on a nearby village.

We'll teach you a spell that will make

your hair stand on end, Lady Doux.

Yay!

Torturing humans with various spells

brings black magicians the utmost joy.

I'm sure if Lady Doux

sees that, she'll also

Now, let us cast the spell.

A FEW MINUTES LATER

Jelly beans?

No, no! This letter is "zue."

It's "Zuraibe Leusa."

You're so funny, Lady Doux!

It's gonna take her five days

to learn a single page.

But this might be more

fun than cursing people.

This is a death plant. They devour

humans down to their bones.

We feed humans who defy demons to them.

The death plants are

especially voracious today.

If she hears the pitiful

screams of the humans

being melted down to their

bones by a death plant,

I'm sure she'll

A FEW MINUTES LATER

Hey! Stop playing around!

Your job is to eat humans!

Take that!

Yah!

Hup!

Take that and that!

Take that!

Yay! I hit them! I hit them!

That's it, Doux!

Yay!

Demons are supposed to be evil

and yet, they keep falling

to Lady Doux's pleasant nature.

I see

So that's why you came to me.

Please

You're the only one I can rely

on at this point, Lady Setia.

Goodness, how pathetic.

Are mermaids demons, too?

Mermaids are demons who lure

in sailors with their song.

We get to sing?!

Yes.

Humans whose hearts are

captivated by our song

willingly throw themselves into the sea

and sink to the bottom.

Big Sister Jahi!

Oh no! My mind's weakened, so I've

been affected by the cursed song

Are you okay?

I'm fine.

Oh? Looks like a ship has

shown up at the perfect time.

Now, come sing with me, Lady Doux.

Let's sing the cursed song.

Okay!

Hey!

What's going on?!

Hi!

Doux's song is so soothing for the soul.

Hi!

Even Lady Setia

Why does this always happen?!

Papa! I'm home!

Ah, you're back!

How many special trials did you do?

Seven!

I see, I see.

Well, Jahi? Has there

finally been some progress?

As I feared

I have failed as Lady Doux's attendant.

We had her accompany various

demons performing heinous deeds,

but there has been no progress.

That's not true! I'm sure

Doux has changed as well.

Isn't that right, Doux? How

were the special trials?

What did you think of them?

Um, well

I thought I wanted to be

more like the other demons!

Lady Doux!

Is that so, Doux?

Yeah!

Isn't that great, Jahi?

Yes!

All of my troubles until now

have finally become worth it.

Now I'll be able to face my father.

Because everyone was so nice!

Huh?

I want to take care of my

friends like the goblins

The black maggie-shuns helped

me learn some new words

I want to sing pretty

songs like the mermaids

Then there's Big Sister Jahi

who's always really nice

and always with me as she

gives me trials to do

Doux wants to be a demon

just like all of them!

I'm nice?

Me?

No, Doux You've got it all wrong.

Pardon me, Your Majesty!

What is it?

Lord Zareth has arrived.

What?

But he wasn't supposed to arrive yet.

THE PREVIOUS DEMON KING IS TOO MUCH OF A DOTING GRANDPA!!

"The Previous Demon King Is Too

Much of a Doting Grandpa!!"

Father!

You should've told us that you were

arriving early so we could greet you.

No need.

It's been a while, Ahriman.

I hadn't been able to return to the

castle after hurting my back.

Nor have I been able to

advise you properly.

I apologize.

No, no, that's no problem at all.

It is a pleasure to meet you.

I am Jahi the attendant.

Thank you for coming all this way.

You must be tired from your long journey.

Allow me to show you to your room.

That can wait.

Huh?

More importantly where's Doux?

D-Did you need to see

Doux for some reason?

I'm asking you where the

next demon king who has

strayed from the path to

becoming a proper demon is.

L-L-Lady Doux is in her room

I have to hurry! I have to hurry!

The next demon king must not

be allowed to stray from the path

of becoming a proper demon.

Are her surroundings causing this?

Is it because you're both spoiling her?

I came here early to eradicate

whatever is getting in the way

of Doux becoming a proper demon.

That is my purpose!

Th-This is bad, isn't it?

Yes, it is.

Is this Doux's room?

P-Please wait, Lord Zareth!

F-Father, I'm sure that Doux must

need to mentally prepare herself.

So please go to the room we've

prepared for you for now

You're hiding something, aren't you?!

Let me see her at once!

Ah! It's Pawpaw!

Pawpaw!

Pawpaw!

Doux! It's been too long!

You've gotten so big!

Come, let me hold you

O-Oh no. I almost forgot why I came here.

That's right. If I spoil her as well,

Doux will never become a proper demon.

Pawpaw!

She will not be able to survive

this cruel demon world!

You must be the demon

that you are, Zareth.

You must be cruel to set

Doux on the right path!

I will find out what is hindering

Doux from becoming a proper demon

and eradicate it!

"HEY, PAWPAW"

LYRICS: KANATA NAKAMURA

COMPOSITION AND ARRANGEMENT: RYOTA TESHIMA

SONG: DOUX

Hey, hey, hey, Pawpaw

Hey, hey, hey, Pawpaw

Look, look, the weather outside

Is just like how I feel

Mr. Sun is smiling

Because I get to be with Pawpaw

I wanna hold your hands

Can I hold your hands?

They're so cold yet so warm

My Pawpaw's hands

I see. So Doux starts off

her days with a walk.

She walks through nature,

picking up acorns, and

collecting fallen leaves

This must be why she's

become such a kind child.

Wait, no!

Walks are unnecessary!

I was about to let Doux's

smile sway me yet again.

I'm accompanying Doux so I can set her

on the correct path away

from these peaceful habits!

Do not forget your mission, me!

Why haven't you realized that this walk

itself is causing Doux to be so kind?!

Make her stop at once!

B-But, but, Father

Pawpaw!

I made you a bed, Pawpaw!

Take a nap here, Pawpaw.

S-So precious!

Doux!

Wait, no, no!

You must resist the temptation, me!

What is this place?

This is our quarry.

We make the enslaved humans work here.

Here!

Oh, thank you.

Er, Lady Doux! Why are you

suddenly helping people?!

Doux!

Oh, hey, everyone!

What should we play today?

She's having fun and smiling.

I was worried about her making friends,

but I guess that was unnecessary.

Humans and demons can see through

their differences and be friends

Wait! She absolutely must

not be friends with humans!

You mustn't be like that, Doux!

This place will poison you.

Never step foot in it again.

But

Understand?

I'm sorry. I'm so sorry, Doux!

Unnecessary! Unnecessary! Unnecessary!

That's also unnecessary!

Unnecessary! Unnecessary! Unnecessary!

This is all for your own sake!

Regarding your schedule for today,

we will begin the celebration

for you at ten in the great hall.

His Majesty will do his opening speech,

then the guests will say a few words,

followed by the executive members,

It's finally the day of

my birthday celebration.

and then we will have you say

a few words, Lord Zareth.

Thank goodness. I won't be able

to keep it together much longer.

Then we will head over

to the great dining hall

to give a toast

and then enjoy the banquet.

Once the festivities are

over, I'll go home at once

Come in.

Good morning, Pawpaw.

Pawpaw, um

Doux has something she

wants to show you today.

So please come to my room

Have you been doing what

I've told you to do?

Not yet.

But, um

Are you still going to

come up with excuses?

If you wish to speak with me,

you must do everything I've

ordered you to do first.

I have better things to do

than play house with you.

Let us go, Jahi.

Y-Yes, but

What? Are you going to

talk back to me, as well?

L-Lady Doux!

Do not chase after her!

Let's go.

Yes, sir.

So that's Lord Zareth

He's really intense.

It's k*lling everyone's appetite

I heard that he'll k*ll

you if you make him angry.

Where's Doux?

Huh?! Well, um

She hates me! Doux hates me!

Wait, why am I lamenting?

I was prepared for this to happen!

I am going to the bathroom.

Lord Zareth!

Leave me be.

This is how it should be.

So that she can cast aside her

kindness and survive as a demon

I had to set Doux on the right path.

This is Doux's room.

Doux?

HAPPY BIRTHDAY PAWPAW!!

HAPPY BIRTHDAY PAWPAW!!

Doux?

HAPPY BIRTHDAY PAWPAW!!

Did you make all of this?

Yup

I wanted to surprise you because

it's your birthday today, Pawpaw.

So I made this and didn't

even tell Papa or Big Sister Jahi.

But I'll make sure to

clean all this up, too

I won't go on walks anymore

and I won't go see

the humans as much

So

I wanna talk with you more, Pawpaw.

Doux!

It's okay! It's okay, Doux!

You can change at your own pace

without having anyone hold you down!

Please forgive me, Doux!

I I was wrong.

I've never received a gift

that made me so happy before!

This goes here.

Like this?

Yup! I'll put one on you, too, Pawpaw!

Oh! Both of you, come help us!

We'll have the rest of my birthday

celebration in Doux's room!

Having a grandchild is wonderful!
