Mr Devil On Guardian Duty!
1
In all the realms of existence, Heaven and Hell had always been enemies.
Angels believed in order and purity.
Demons believed in freedom and chaos.
For countless centuries, the two sides fought endlessly.
A Certain Kingdom stood in the center of both realms unlike any other
The kingdom where angels and demons lived side by side was never truly quiet
But under the rule of King Kairos Ven Alvarez and Llewyn Kilyziah-Alvarez, the strongest Archangel in Heaven, balance had always been maintained.
Unfortunately, that balance had one very specific weakness.
The sky above Vyltheris was glowing an alarming shade of crimson.
Half the training courtyard had been blown apart.
Angelic runes were shattered, demonic flames burned across the marble ground, and several terrified angels were currently flying away from a rampaging infernal beast.
In the middle of the chaos stood Vion.
Looking at the destruction.
Then back at the destruction.
VION LOUIS ALVAREZ : MC
…Oh shit.
The enormous creature roared.
Vion quickly raised both of his hands
VION LOUIS ALVAREZ : MC
Okay listen!! This is a misunderstanding
Vion vanished in a flash of dark energy.
The royal palace of Vyltheris
Vion stood in the middle of the massive throne hall with his hands behind his back, trying his best to look innocent.
Unfortunately, It wasn’t working.
In front of him stood two very powerful and very irritated beings.
The King of Hell, Kairos Ven Alvarez, sat lazily on the throne, long legs crossed, looking far too amused for the situation.
Beside him stood Llewyn Kilyziah-Alvarez, his golden eyes narrowed in pure disappointment.
Which was somehow much worse than anger.
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
Explain.
VION LOUIS ALVAREZ : MC
**cough** Well… technically speaking… the demonic beast wasn’t supposed to escape.
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
And why were you summoning an ancient infernal beast in the Heaven training grounds?
VION LOUIS ALVAREZ : MC
Scientific curiosity?
The temperature in the room dropped instantly.
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
**Cold** Prince Vion Louis Alvarez.
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
You have destroyed half a training court, frightened twelve angels, angered three demon generals, and nearly started a fight between the angels and Demons here
VION LOUIS ALVAREZ : MC
Um...
Vion slowly turned his head toward the throne
His eyes locked onto his other father.
Kairos raised his eyebrow
VION LOUIS ALVAREZ : MC
“Help Me”
Kairos thought about it then shrugged.
KAIROS VEN ALVAREZ : VION'S DAD
Sorry Kid, If i wanna get that Angelic Dick in me
KAIROS VEN ALVAREZ : VION'S DAD
I gotta stay on your Dad's side
VION LOUIS ALVAREZ : MC
FATHER!
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
**Pinches the Bridge of his nose** Language, My Dear
KAIROS VEN ALVAREZ : VION'S DAD
I’m just being honest
Vion pointed dramatically at the Kairos
VION LOUIS ALVAREZ : MC
You’re seriously abandoning your own son?!
Kairos leaned back in the throne and raised his hands in surrender
KAIROS VEN ALVAREZ : VION'S DAD
Don't look at me
KAIROS VEN ALVAREZ : VION'S DAD
Your Dad’s scary when he’s mad.
VION LOUIS ALVAREZ : MC
Seriously?! What kind of father are you!?
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
Enough!.
Both Kairos and Vion went quiet.
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
You have caused trouble for centuries Vion.
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
Warnings. Punishments. Restrictions. None of it has worked.
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
So, I have decided on a different solution.
VION LOUIS ALVAREZ : MC
**Blink** What solution?
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
Earth.
The word echoed through the hall.
VION LOUIS ALVAREZ : MC
Excuse me?
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
You will leave Vyltheris.
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
You will go to Earth and YOU will complete an assignment.
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
And until that assignment is finished you are not allowed to return.
Vion stared at him in horror.
VION LOUIS ALVAREZ : MC
You’re kicking me out?!
KAIROS VEN ALVAREZ : VION'S DAD
**Impressed** Oh. That’s harsh.
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
You will act as the guardian of a human boy. Protect him. Help him. And most importantly--
He looked directly into Vion’s eyes.
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
Become responsible.
VION LOUIS ALVAREZ : MC
**Points at himself** Me? Responsible?!
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
Yes.
VION LOUIS ALVAREZ : MC
This is discrimination against chaotic personalities!
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
I don't care.
VION LOUIS ALVAREZ : MC
Dadd Pleaseee!!
VION LOUIS ALVAREZ : MC
This is seriously Unfair!!
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
You are going to be out of Vyltheris.
A magical seal appeared beneath Vion’s feet.
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
Get to Earth.
Another seal appeared in the air.
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
Finish the assignment given to you
Light began to swallow the room.
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
And become FUCKING RESPONSIBLE.
VION LOUIS ALVAREZ : MC
WAIT--!!
KAIROS VEN ALVAREZ : VION'S DAD
Bye kiddo
Before Vion could protest further--
And the most troublesome prince of Vyltheris was sent straight to Earth.
2
That was the first thing Vion felt.
Not physical pain, but the uncomfortable sensation of his entire existence being squeezed through a portal.
Vion crashed face-first onto solid ground.
CHOI SEONG-HUN : VION
Ow..
He slowly pushed himself up and looked around.
Strange metal vehicles rushing past.
CHOI SEONG-HUN : VION
This place looks depressing..
A few nearby pedestrians glanced at him strangely before continuing on their way.
Vion dusted off his clothes and sighed dramatically.
CHOI SEONG-HUN : VION
So this is Earth.
A faint glowing screen suddenly appeared in front of him.
CHOI SEONG-HUN : VION
What?
The screen flickered again.
GUARDIAN SYSTEM ONLINE
System Name: Ryuu
A voice spoke calmly in his mind.
Unknown
Greetings Your Highness, Prince Vion
CHOI SEONG-HUN : VION
Who the hell are you?
Unknown
I am Ryuu, your assigned guardian system.
CHOI SEONG-HUN : VION
Appear infront of me first.
A holographic Image of a Little Rabbit appeared infront of Vion
RYUU : SYSTEM
**Bows a bit** Greetings
CHOI SEONG-HUN : VION
Who assigned you?
RYUU : SYSTEM
His Majesty Llewyn Kilyziah-Alvarez.
CHOI SEONG-HUN : VION
**Groan** Of course he did
CHOI SEONG-HUN : VION
**Sigh** tell me what are you here for?
Ryuu clapped his paws and the screen appeared again
Protect and guide: Kang Min-su
Age: 17
Location: South Korea
CHOI SEONG-HUN : VION
**Rubs his forehead** Alright… where is this human?
RYUU : SYSTEM
He is currently attending Hanrim Technical High School.
CHOI SEONG-HUN : VION
**raises his eyebrow** Sounds normal enough.
Then another message appeared.
SCHOOL CLASSIFICATION : Delinquent Institution
CHOI SEONG-HUN : VION
**stares at it** Come again?
RYUU : SYSTEM
The school and surrounding institutions are dominated by delinquent groups
RYUU : SYSTEM
Each school operates under student leaders who function similarly to gang organizations.
CHOI SEONG-HUN : VION
So you are going to send me into gang territory?.
CHOI SEONG-HUN : VION
**Grin** Wonderful
The screen displayed a picture of a boy
CURRENT STATUS : Errand Boy
CHOI SEONG-HUN : VION
**Frown** Okay..What does Errand Boy mean?
RYUU : SYSTEM
As Kang Min-su is frequently bullied.He is forced to run errands for several students within the school.
CHOI SEONG-HUN : VION
You got to be kidding me..
He pointed at the screen.
CHOI SEONG-HUN : VION
This weak human is my assignment?
Vion looked up at the sky dramatically.
CHOI SEONG-HUN : VION
I, the prince of Vyltheris… I was sent across realms…
He pointed at Min-su’s photo again.
CHOI SEONG-HUN : VION
…to babysit a bullied errand boy?
Then another notification appeared.
CHOI SEONG-HUN : VION
**Frown** What is this now?
RYUU : SYSTEM
Due to your history of reckless behavior, your supernatural powers have been restricted.
CHOI SEONG-HUN : VION
Excuse me?
RYUU : SYSTEM
You may only use your abilities when the system determines it is necessary.
CHOI SEONG-HUN : VION
**Eye twitch** So I can’t just use my powers whenever I want?
CHOI SEONG-HUN : VION
And who decides when it’s necessary?
CHOI SEONG-HUN : VION
This is torture.
The screen displayed the final message.
• Protect The Target Kang Min-su
• Failure to protect the target may result in additional restrictions.
Vion looked back at Min-su’s picture and sighed again.
CHOI SEONG-HUN : VION
Fine.
He cracked his knuckles slowly.
CHOI SEONG-HUN : VION
Since this brat belongs to me now…
A faint demonic glow flickered briefly in his eyes before fading.
CHOI SEONG-HUN : VION
**Evil Grin** Those bullies are about to experience something worse than hell
RYUU : SYSTEM
Reminder: you are a guardian. Not an executioner.
CHOI SEONG-HUN : VION
**Smirk** No promises.
Somewhere nearby, a nervous boy named Kang Min-su was currently running errands for a group of delinquents.
And he had absolutely no idea…
That a chaotic half-devil prince had just arrived on Earth to become his guardian.

^...^ thinking or talking in mind
Hanrim Technical High School.
Several groups of students stood around the entrance, smoking, fighting, or loudly arguing.
Vion stood at the gate with his hands in his pockets.
CHOI SEONG-HUN : VION
This is a school?
CHOI SEONG-HUN : VION
**Squints his eyes** It's too...simple
Ryuu turns his head here and there
RYUU : SYSTEM
Looks more like a battlefield.
CHOI SEONG-HUN : VION
Back at home, it used to be far worse
CHOI SEONG-HUN : VION
**Sigh** What can you expect from humans..
Vion sighed and walked inside.
The door slid open and the teacher walked in.
The entire class immediately looked up.
Most of the students had dyed hair, piercings, or bored expressions.
Well so did Vion so meh..
The teacher spoke lazily.
Teacher
**Yawn** We have a transfer student.
He wrote a name on the board.
Teacher
Introduce yourself kid.
Vion looked at the class.
CHOI SEONG-HUN : VION
…I’m Choi Seong-Hun.
He pointed toward an empty seat in the end of the middle row
Without another word, the teacher walked out of the classroom.
Apparently introductions were not very important at Hanrim.
Vion walked over and dropped into the seat.
CHOI SEONG-HUN : VION
^Ryuu^
CHOI SEONG-HUN : VION
^Where’s the human?^
A small map appeared in Vion’s mind.
RYUU : SYSTEM
Kang Min-su is currently inside this classroom.
CHOI SEONG-HUN : VION
**Blink** He is?
Vion casually looked around the room.
None of them looked like the nervous boy from the photo.
CHOI SEONG-HUN : VION
^Which one?^
RYUU : SYSTEM
Three seats to the right. First row
When someone slammed their hand onto his desk
A tall boy with blond hair and several piercings was glaring down at him.
MIN JINWOO
Dumbass, where are you from?
The classroom immediately grew quiet.
Several students turned to watch.
Vion stared at the boy for a second.
CHOI SEONG-HUN : VION
You walked all the way over here just to ask something that stupid?
MIN JINWOO
What did you say!?
Vion rested his chin on his hand.
CHOI SEONG-HUN : VION
I said it was stupid.
He looked the boy up and down.
CHOI SEONG-HUN : VION
You should get your hearing checked.
The blond boy’s face turned red from anger
He raised his fist and swung it toward Vion.
RYUU : SYSTEM
WARNING : Avoid unnecessary violence!!.
Vion caught the punch easily.
MIN JINWOO
**Blinks in shock**
His grip tightened around the boy’s wrist.
CHOI SEONG-HUN : VION
**Eye twitch** You tried to punch me?.
RYUU : SYSTEM
Prince Vion. Please Remain cal--
Vion slammed the boy’s head straight into the desk.
The desk rattled loudly as the whole class went quiet
The blond boy groaned, half-dazed.
Vion released him and adjusted his sleeves casually.
RYUU : SYSTEM
Prince Vion, please stop.
A glowing message appeared in his vision.
EMERGENCY BEHAVIORAL PROTOCAL ACTIVATED
CHOI SEONG-HUN : VION
**Frown** What now?
RYUU : SYSTEM
Activating calming methods provided by his majesty Llewyn Kilyziah-Alvarez.
CHOI SEONG-HUN : VION
I don’t like the sound of that...
A familiar cold voice suddenly echoed inside his mind.
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
Vion.
CHOI SEONG-HUN : VION
What?..
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
If you cause trouble on Earth…
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
I will personally burn every single one of the hidden magazines under your bed.
CHOI SEONG-HUN : VION
The fuck..
LLEWYN KILYZIAH-ALVAREZ : VION'S DAD
Don't try me kid
ADDITIONAL MESSAGE BY HIS MAJESTY
And the next time you start a fight for no reason..I’m informing your brothers.
Vion’s entire body stiffened.
CHOI SEONG-HUN : VION
That’s low.
RYUU : SYSTEM
Calming method successful.
CHOI SEONG-HUN : VION
**Grits his teeth** This is psychological torture.
Around him, the class was still staring at the unconscious blond boy.
RANDOM STUDENT
Did the new guy just destroy Jinwoo?
Random Student
He’s insane.
Vion sat down again like nothing had happened.
CHOI SEONG-HUN : VION
^Ryuu if you stop me next time i swear you and me are going to have a problem^
RYUU : SYSTEM
It's my duty to make sure you don't cause trouble,your highness
Vion groaned as he leaned back against his chair
