If you don't know koro q is basically a spin off where everyone has magic and based on how many enemies you fight you level up

e class has these bugs which seperates them from the rest of kunugigaoka (in the spin off it's a school or magic)

Blah blah blah Koro~sensei is the demon king and e class is meant to kill him

The 3 transfer students (Karma, itona and Ritsu) are high level warriors

(Karma refers to himself as the 'red devil' which is why the title says red devil karma)

In the spin off Gakuho is the Pope and the big 5 are his loyal warriors.

Just go watch it all the episodes are on YouTube or somewhere

-------------

When you were 8

You were apart of the Royal Family, next to the throne to be exact

With that fact your parents were strict with you, giving you lessons, trapping you in your room during free time, constant guards around you, etc.

Because of that you got bored and ended up sneaking out often, it was bound to happen from how strict they were.

(Already have a rebellious phase, I'm so proud of you)

They started to notice and thought about giving you a personal guard to watch over you since they both knew you would not stop sneaking out, they thought someone your age yet able to protect you.

The Pope knew this since you attended his school (since it was the best magic school in the land) and decided to make a deal with your parents of making his son your personal guard

He was your age, he was talented, he is able to protect you, he's high in levels and magic. They had no reason to refuse.

And that's how Asano became the royal guard and your only friend

When you were 10

You giggled as you ran out the castle and into the field, Asano following you from behind

"Prince! You can't just run off like that" Asano shouted while trying to catch up to you

You giggled and carried on running of until you dumped into a cave

"See, you shouldn't be running of or you will get hurt" Asano said while rubbing your head were you hit the rocks

"Tha-" Asano looked behind him, his eyes widened and he covered your mouth

"Shhh"

You looked behind you to see a big dragon

Asano pulled out his sword but you stopped him

"Wait don't kill it" you whispered/shouted

"What?!? It's a gigantic dragon" he whispered/shouted back

"But it hasn't hurt anyone"

Asano sighed and put his sword back in his belt

You noticed the sword attacked to the big Dragons throat and you could feel a pain in your heart

"I think it's already dead... Poor thing"

"Yeah yeah that's sad, come on we need to get you back to the castle" he grabbed your arm and was about to drag you out until you heard a noise, you both looked back to see a baby dragon, it looked like a new born

"We need to go!"

"Hey baby"

"Why aren't you listening to me!!"

You got some food from your pocket and kneeled down so the baby dragon could walked up to you and eat it

"You can't feed a dragon! It will hurt you!"

"It's just a baby" at this point the dragon was sniffing your food before eating it in your hand

"We have to go! Why aren't you listening to me?!?"

The dragon climbed into your legs and licked your face making you giggle

"I think he likes me"

(Yes the dragon is a he)

"Can we keep him?" he turned your head to Asano

"We? No we can't take him"

"But his mother is dead"

"At birth babies leave their mothers he'll be fine on his own"

"Please" you gave him the puppy eyes

"*sigh* your explaining it when we get back to the castle"

You picked the baby dragon up and ran to Asano so you both could go home

"You know when your parents said you can have a Royal pet, I don't a dragon was what they meant"

You Giggled and you both went back to the castle

Timeskip (your both 14-15)

"This is your Prince (y/n) (L/n), he will be helping you with killing the demon king"

"You got royalty!" the whole class responded

(This is at episode 1 so Karma isn't introduced yet)

"Actually he asked to be apart of this, only the pope and royalty know the demon king is here"

You walked up to the demon king

(Btw at this point your dragon is about 5ft tall since it's been a couple of years)

"You don't look all that mean and scary, you look squishy"

The demon kings instant responce was to wrap his..... "Arms" around you

"Can we keep him?" the demon king asked Mr Karasuma

"the prince is not a pet!"

Timeskip to maybe month or so (cause I'm so lazy that sloths look up to me and say 'teach me your ways oh lazy one')

"This is the 5th time I've caught you sneaking out to go to that class full of bugs" Asano complained while dragging you by the hand down the mountain

"But-"

"There is no reason you should be hanging out with those bugs, you are royalty and if anyone catches you hanging around those misfits the Royal's family reputation will to down hill"

You rolled your eyes honestly not carrying

'No one will catch me anyway'

You felt someone grab you hand making your eyes widen in shock and making Asano stop and turn around

"Can you honestly blame little mr royalty over here, they are always cooped up inside the castle"

You looked to see non other then Karma

"Reframe from touching royalty without permission" Asano said gritting his teeth

Karma swung his arms around your shoulder to piss Asano off "or what?"

Asano gritted his teeth knowing he can't hurt someone in your presents without your order

"And just because I want to" Karma leaned close to you and kissing you and your lips making your eyes widen in surprise

Asano got mad and pushed Karma of you with you behind Asano

"You can't Just kiss royalty without consent"

Meanwhile you were flustered with one hand on your lips from the kiss

"Are you saying that out of respect or because you don't have the guts to kiss him yourself?" Karma teased

Asano blushed out of embarrassment

Everyone knows Asano doesn't like it when people say be was too scared to do something

So he softly but his hand on you cheek and kissed your lips but pulled away before you could process

And that was the start of your secret 'affair' with that Royal Guard and the Red Devil

I bet this was mega confusing for people that haven't seen Koro q
