Britannia.
Once in this realm, the Holy Knights of Liones Kingdom staged a coup d'état,
sparking a conflict that escalated into a Holy War
between the goddess clan and the demon clan.
The devastating fires of war threatened to consume the entire continent,
but the emergence and active involvement of the legendary heroes
known as the Seven Deadly Sins brought an end to the war.
This story takes place 16 years after those events.
We've arrived at Echo Gorge.
Percival is in there?
THE DEMON OF ECHO GORGE
This place sure looks like it'll grab a little kid's interest.
Why'd he have to cause trouble for us?
If anything happens to him, I'm going to catch all the heat.
Searching for him might be a lost cause at this point.
Yeah, he's likely fallen prey to Nasiens by now...
Is this guy that dangerous?
We saw with our own eyes!
Dammit. Let's hurry!
Huh? Where's my helmet?
I don't have my cape either!
Strange.
You weren't supposed to wake up for 10 hours.
Oh, it's you!
What have you done to me? Why did you strip me naked?
I need my guinea pigs to be clean.
Give me back my helmet and cape!
They're keepsakes of my grandpa!
Your clothes were burnt and on the verge of falling apart.
I'm afraid you can't wear them now.
Your helmet and cape are over there.
They have strong magic in them.
They're rare magic items.
M-Magic items?!
I won't steal them.
But that is one thing.
This is another.
In an hour, the potion should start taking effect and...
Interesting.
This isn't interesting!
- I didn't expect such noticeable results. - I can't put on my helmet like this!
- I must have got the quantities right. - What are you going to do about it?!
What exactly are you planning?!
You were about to do something terrible to the fairy earlier, weren't you?!
It is true I intended to make him my guinea pig,
but he's the one who barged into my home and attacked me.
B-But you...
Who are you?
You bit the fairy and had blood dripping from your mouth!
I've taken a liking to you.
It's easy to see the effects on you, and you recover quickly.
You're the ultimate guinea pig.
There you go again!
Oh, I've had this habit of biting my lip
whenever I get excited since I was a little kid.
I think you should work on breaking that habit.
She used to tell me that often...
My older sister, I mean.
What's going on?!
Every single creature is attacking us!
This is all Nasiens' doing!
His strange potions and experiments are the cause of all these evils!
What a terrible villain!
We have to beat him up quickly, otherwise Percival...
Nasiens isn't like that! Don't get him wrong!
I apologize for misunderstanding you.
But I have to go now.
This next concoction experiment will be the last.
Really?
However,
if I have gotten the quantities wrong, even just a little...
you will die.
Are you shaking?
Why are you doing something like this?
I have a goal I must achieve.
I've got a goal I have to achieve as well!
To find my dad who killed my grandpa and kick his butt!
And to explore the strange places throughout Britannia!
I don't have time for this.
Henbane! Belladonna!
I won't kill you.
Is that also magic?
Hold on, my helmet...
Listen to me! If you're in trouble, I'll lend you a hand!
A complete stranger like yourself?
All I want is a guinea pig to test this concoction.
But I can't afford to test it myself.
If I die, I won't be able to finish the potion or save the gorge.
The gorge?
That's enough with the idle talk.
This is your precious potion.
W-Wait! Fine!
I won't hurt you anymore!
So please, hand me that potion!
I won't!
If I handed it to you, you'd test it on someone else.
Sto...
I'm so close to completing it. No, it should already be completed!
You're out of your mind to willingly drink poison...
Wh-Why did you do that?
It's so bitter...
Could it be that it didn't work?
Throw it all up right now!
My whole body is feeling a burst of energy!
I'm so energized I can't help but shout something!
Bam!
Blockhead!
That stupid echo!
Seems like he's safe.
I feel a little better now.
Why?
Why did you do something so reckless despite knowing the risks?
I don't really understand the situation,
but you made that potion to save the gorge, didn't you?
Did it work?
Judging by your symptoms, it's as clear as day.
It worked.
I see.
That's great!
My name is Nasiens.
What's yours?
Percival. I hope we get along!
Thanks to you, I can save the gorge.
Is that small amount going to be enough?
Huh?
Huh?!
Percival!
Huh?
Donny!
You! What happened to make that happen?!
Save the gorge?
Yeah, that's what he said.
He won't fool me! His potions weren't anything like that!
Or... do.
Ordo? Is that someone's name?
Ordo is the old herbalist who used to live in this gorge.
Ordo came before Dolores or Nasiens were around.
Hey.
Oh my, I didn't know there were fairies around.
I'm sorry for not greeting you.
What on earth are you doing?
I'm a herbalist, you see.
This place is a treasure trove of ingredients.
Of course, I have no intention of recklessly harming this beautiful gorge.
If you ever get hurt, please come to me.
Ordo!
There's a lost Giant!
Is that so?
You must have been uneasy outside your village.
If you want, you can stay here for as long as you like.
Huh?
Oh, my!
A human baby?
Was he abandoned?
This mineral is amethyst, an ingredient used for herbal medicine.
This plant is poison hemlock. It is highly poisonous.
Be sure to handle it with great care.
Why is it poisonous?
That is because...
Where is this Ordo guy?
He vanished from the gorge.
What?
That's when it started.
That's when Nasiens started his strange experiments.
Before that annoying brat does anything uncalled for,
let's destroy this forest quickly.
Am I clear, Ordo?
Nasiens.
Q-Quickly, I must give the completed concoction to the gorge.
You shouldn't push yourself yet.
The decay has been accelerating in these past few days.
Quickly, before it's too late!
Nasiens! You're really set on destroying the gorge this time, aren't you?
You've got it all wrong!
We're not wrong! We all saw it!
I bet Ordo left because he realized Nasiens' true nature!
Get out of the gorge, you devil's spawn!
Grab, grab, grab, grab!
Why?
Hey, human! Why are you shielding him?!
Shut up!
Nasiens was trying to make a potion to save the gorge!
Wait a minute!
What's going on?
The forest is withering away.
Even the animals. How can it be?
There is no time. I will use the potion.
But there's no potion left anymore!
No, there is.
This color... It's what you and I just drank!
By taking poison myself and having my body remember it,
I can create and mix poison at will.
That is my magic, venom mixing.
Everyone, cover your mouth!
Misty Rain.
The mist is spreading all over the gorge.
It must be the wind blowing down from the air hole.
I can't believe it. The gorge has been restored.
Seriously?
Hey, why poison?
To heal wounds and illnesses,
you need to understand everything about poison first.
Poisonous herbs, poisonous creatures, and mineral toxins...
Depending on how you use them, you can create remedies from them.
This is what Ordo, my grandfather, used to say.
"You cannot save lives without understanding poison."
I hope you can meet your grandpa again.
Yes. I want to see him again.
Phew, much better!
The clothes I made for Nasiens fit you perfectly.
Good thing you're super tiny, huh?
Yeah. Lucky me!
Helmet on!
Forgive us, Nasiens.
We assumed it was your potions that made the gorge turn strange.
We really acted terribly toward you.
It's fine.
Besides, it's true that the animals in the gorge were turning vicious
due to the side effects of my potion.
It must be painful for you right now, but please work with me.
I promise to restore everyone and this gorge back to normal.
What caused the gorge to end up like this?
I don't know.
Ever since the day Ordo disappeared,
the vitality of the animals and plants has been fading away.
Nasiens!
Hey!
I would rather have you thank him than apologize to me.
The poison that could counter a deadly disease
could have wiped out the gorge if not mixed correctly.
But he willingly became a guinea pig for it.
Check it out!
I can't wear my grandpa's clothes anymore, so I'm wearing yours!
Woo-hoo, here's the hero of the gorge!
Thanks, guinea pig!
Thank you.
Wh-What?
Wow, cool! You have wings!
This so-called forest disease seems to have affected even the soil of the gorge,
not just the animals and plants.
In other words, it contaminated the entire gorge.
Wait a minute.
Could the cause be related to the wind from the air hole?
Percival!
Huh?
Is that a monster?
Ordo?
Huh?
That's Nasiens' grandpa?
He's three times bigger than my grandpa!
Like that can be true!
Ordo!
Why do you look like that?
Wait!
No way. The forest is decaying...
Aren't you interested in leaving this gorge, Ordo?
I'm not.
This is a vital research site for a herbalist,
and it's also my home where you, and all my family, live.
Ordo! Stop!
Please stop!
This gorge is your home, isn't it?!
Please say something!
Rather... than... by...
Destroy the gorge, destroy!
Nasiens!
Let him go!
Are you going to hurt your own family?
Dolores.
No! It can't be! Why did you hurt her?!
Quit wailing, you brat!
All of this happened because you meddled in the first place.
Just as I thought, the matter-of-fact and solemn aesthetics of death
are too hard for a brat to understand.
It's the fairy that Nasiens had captured...
He's the mastermind who turned the herbalist into a monster.
What?
A talking fox?
I'm impressed that you figured it out.
Why are you doing something like this?
Why?
Because this herbalist is a criminal.
Now, Ordo, destroy the gorge to atone for your sins.
What should I do?
Let's turn your grandpa back to normal!
Together!
Percival...
